EAO has extended its Series 82 pushbutton switch line with an overmolded option and M12 connector. The new version is available for selected illuminated pushbuttons in the Series 82.  Illuminated versions are available with red, green, white, or blue LEDs. The switches offer complete front and rear IP67 protection for harsh operating environments. Examples include in the food & beverage industry where alkaline cleaning agents and corrosion severely affect HMIs, said EAO. Switches are also subjected to hard-to-remove dirt, fine dust, severe vibrations, and blunt impacts in heavy-duty and special-vehicles applications, requiring a very high level of resistance. The overmolded version can meet these strict requirements. These illuminated pushbuttons feature a housing made from SUS 316L stainless steel and a Tritan light guide that is resistant to cleaning agents. These design features provide protection against wear and ensure consistent clarity of both the dot and the ring illumination, said the company.

Flex Power Modules has expanded its PKU-D series of low-profile sixteenth-brick DC/DC converters with the PKU3913D, a 100-W rated part with an extended input range down to 30 V and regulated output of 12 V/8.3 A. The intended application is for nominal inputs of 48 V or 54 V with possible long cable lengths and consequent voltage drops such as microwave radio links, said the company. The input range  of 30 V to 60 V is compatible with PoE standard IEEE 802.3af (37-57 VDC). The PKU3913D is designed for high efficiency at lower input voltages, peaking at over 95%. The parts feature pre-bias, monotonic start-up capability, remote on/off, and an MTBF of 13.88 M hours at 40°C ambient according to Telcordia standards. Products are certified to IEC/EN/UL 62368-1 for 2250 VDC input-to-output isolation. Circuit protection functionality includes over-temperature, input under-voltage, and output over-voltage, over-current, and short circuits. The PKU3913D series is housed in a 33.02 × 22.86-mm footprint with a 11.3-mm height in the open-frame formats, with optional through-hole or SMT termination, or 12.7-mm high for the pinned version with optional base plate. Size and pin-out is industry-standard.

Hirose has added a waterproof panel-mount connector to its in-line product offering. The DF62WP wire-to-wire connector series offers an IP67 equivalent waterproof seal between the cable and socket (outside panel) or panel and plug (inside panel). The crimped contacts and wire can be easily inserted through the seals to complete the rugged cable assembly, said Hirose. Part of the SignalBee product family, the DF62WP wire-to-wire connector series offers a multi-row pin layout arranged in a grid pattern that significantly reduces the size of the diagonal diameter. It uses a highly reliable two-point contact design and is resistant to shock and vibration. The connectors measure 61.8 × 19.0 × 23.25 mm with a 2.2-mm pitch. Supporting #20, #22, #24 and #26 AWG, the DF62WP connector series is currently available with 15 total contacts configured in groupings of 3-, 4-, 6-, and 2-contacts, respectively. Key specs include a current rating of up to 5 A, a voltage rating of 250 VAC/DC, and a maximum of 30 mohms contact resistance. Mating is ensured for up to 30 full insertion/withdrawal cycles. The DF62WP Series has an operating temperature range of -40°C to 105°C and is Halogen-free as defined by IEC61249-2-21. Applications include consumer and home appliances, automatic ticket gates, food process machinery applications, LED lighting, motorized bicycles, medical devices, security systems, and robotic machinery.

Littelfuse, Inc. has introduced the Pxxx0S3N SIDACtor Protection Thyristor Series that protects exposed interfaces in industrial and ICT applications, including RS-485 data interfaces and AC/DC power supplies. The series provide equipment in harsh environments with increased protection from severe over-voltage transients and helps designers comply with regulatory requirements. These applications include AC and DC power lines in factory automation, power interfaces for energy storage systems, DC/AC inverters in solar energy systems, UPS/AC high-power distribution grid, and electric-vehicle charging systems. Available in a compact, DO-214AB (SMC) package, the Pxxx0S3N SIDACtor series delivers 3 kA (8/20) high-power surge protection with low thermal accumulation during long-term overvoltage events. Littelfuse said the Pxxx0S3N provides a much lower switching voltage (VS) than gas discharge tubes (GDT), and the on-state voltage (VT) is much lower than metal oxide varistors (MOV) and transient voltage suppressor (TVS) diodes. The Pxxx0S3N also is said to offer superior lower clamping when used with a series-connected MOV for power line protection.

NXP Semiconductors has launched a new family of RF power transistors for 32T32R active antenna systems, using its latest proprietary gallium nitride (GaN) technology. Complementing NXP’s existing portfolio of discrete GaN power amplifier solutions for 64T64R radios, the new series expands coverage to all cellular frequency bands from 2.3 to 4.0 GHz. NXP said it now offers the largest RF GaN portfolio for massive multiple input, multiple output (massive MIMO) 5G radios. The new 32T32R discrete solutions are said to deliver twice the power in the same package as 64T64R solutions, resulting in smaller and lighter weight 5G radios. “By combining 32 antennas instead of 64, coverage can be maintained more cost effectively, while maintaining the high-end 5G experience enabled by massive MIMO,” said NXP. The new series is designed for 10 W average power at the antenna, targeting 320-W radio units, with up to 58% of drain efficiency. It includes driver and final-stage transistors and leverages NXP’s highly linearizable RF GaN technology.

Stackpole Electronics, Inc. has improved the temperature coefficient of resistance (TCR) of the RMCW series of wide-terminal chip resistors. They offer an improved TCR of 200 ppm for resistance values from 1 to 10 ohms for better performance over a wide range of temperature. Wide-terminal chip resistors provide terminations on the long sides of the chip to provide better current handling and thermal resistance, resulting in lower PCB temperatures for a given chip size and power rating and better overall stability performance, said Stackpole. The RMCW series is available in resistance values from 1 ohm to 10 Mohms in 1% and 5% tolerances. Applications include power management, battery charging, motor controls, industrial machinery, and appliances. Pricing ranges from $0.016 to $0.115 each in full reel quantities, depending on tolerance and resistance value.

STMicroelectronics has introduced the L9908 integrated automotive three-phase gate driver unit (GDU) for brushless DC motors. The gate drivers operate in 12-V, 24-V, or 48-V systems and offer flexible input and output channels for a variety of applications in conventional and hybrid/electric vehicles. The devices offer a wide motor supply-voltage range from 4.5 V to 75 V, with the ability to tolerate -14 V to 95 V on motor-connection pins. The on-chip logic is supplied from an internally generated 3.3-V supply and digital I/Os are 3.3 V- and 5V-compatible. Dedicated source connections to the high-side and low-side FETs (field-effect transistors) of each half bridge let users configure the output channels independently to drive various types of loads, said ST. The devices also offer  separate pulse-width modulation (PWM) input pins that allow independent management of the pre-driver stages for different motor-control strategies. Safety features include SPI-programmable dead-time insertion with shoot-through diagnostic and protection, open-load detection, and short-to-ground and short-to-battery diagnostics. Other features include SPI-programmable temperature warning and SPI-readable junction-temperature measurement. Other diagnostics include ground-loss detection, over-voltage and under-voltage detection on the power supply pins and FET-driver supply, system-clock monitoring, SPI window watchdog, and a fault-status flag. The built-in diagnostics allow the devices for use in safety-related systems such as autonomous emergency braking (AEB) and advanced electronic power steering (EPS), simplifying certification according to ISO 26262. The AEC-Q100 qualified L9908 is available now in a thermally enhanced TQFP48 package. Pricing starts at $3.56 for orders of 1000 pieces.
