TDK Corp. has developed new chip NTC thermistors that are designed for conductive adhesion mounting. The automotive-grade devices are used for temperature sensing and compensation, measuring without direct contact in automotive applications including anti-lock braking systems (ABS) and inside the transmission or engine.
The NTCSP series, certified by AEC-Q200, uses silver palladium alloy (AgPd) termination, which enables conductive adhesion mounting. This makes the NTC thermistors suited for applications where soldering is difficult, said TDK.
The NTCSP devices are available in 10 kΩ, 47 kΩ, and 100 kΩ types with dimensions of 1.0 × 0.5 mm and 1.6 × 0.8 mm. With a wide operating temperature range from -55°C to 150°C, the NTCSP series can be used in a variety of temperature measurement and compensation roles in low- to high-temperature ranges.

TDK also offers a web-based tool for calculating the resistance/temperature (R/T) characteristics of the current portfolio of EPCOS NTC thermistors. The NTC R/T Calculation 5.0 tool enables R/T characteristics to be individually calculated and manipulated by adjusting the temperature range and the resistance tolerance and selecting the desired temperature intervals, said TDK. In addition, users can now tell which products are not recommended for new designs. The results can be supplied as PDF files or exported in spreadsheet-compatible csv format.
