Ametherm has extended the capabilities of its ACCU-Curve series of interchangeable NTC thermistors with the new ACL-011. The devices feature insulated tinned-copper leads to ensure the most accurate temperature sensing with no unintended conduction between leads, said the company. Applications include long-term stability and reliability for high-accuracy temperature sensing, control, and compensation in medical, industrial, and automotive applications.
The thermistors offer interchangeability over a broad temperature range and eliminate the need to individually calibrate or provide circuit compensation for part variability, according to the company. As less-expensive alternatives to RTD probes and thermocouples, the devices deliver the tight tolerances required for accurate temperature measurement in medical instrumentation and can be potted in a variety of housings for temperature compensation circuits in industrial and automotive applications.
Key specs include:
- Resistance at 25°C 50 kΩ ±1% tolerance
- Dissipation constant 3 mW/°C min
- Operating temperature range of –40°C to 125°C
- Thermal time constant 12 s
- Beta (25°C/50°C) = 3,950 K
- Max. power rating 50 mW
- Insulated tinned copper leads
The ACL-011 is available directly or through distributors such as Digi-Key and Mouser. Samples and production quantities are available now with lead times of 12 weeks for large orders. Volume pricing starts at $1.37 per piece for U.S. delivery.
