Thermometrics NTC Thermistors
Surface Mount Devices (SMD)
Thermometrics Surface Mount Devices (SMD) Series of NTC Thermistors are intended for temperature measurement, control and compensation. They are suitable for standard soldering techniques and availabe in a range of sizes, including 0402, 0603, 0805 and 1206.
- Temperature measurement, control and compensation
- Standard soldering techniques
- Nickel barrier tin-plated terminations for soldering
- High sensitivity to changes in temperature
- Wide operating temperature range -40°C to 125°C
- Rugged construction
- Excellent solderability without “tombstoning”
- Glass-coated ceramic between electrodes for improved stability
- Supplied in tape-and-reel packaging
- Available in other material systems
