Vishay Intertechnology has extended its NTCS0603E3.....T and NTCS0805E3.....T series of Automotive Grade, glass protected NTC thermistors in the 0603 and 0805 case sizes with new electrical resistance values at +25C (R25). The AEC-Q200 qualified devices are now offered with lower R25 values of 1kOhm and 1.5kOhm, in addition to a new 5kOhm value optimised for the protection of IGBT and power MOSFET modules in EV and HEV vehicles.
Fully glass coated and protected, the enhanced thermistors provide tolerances down to ±1% for their R25 and beta (B25/85) values for precise temperature sensing, protection, and compensation over a broad temperature range from -40C to +150C. Smaller than MELF resistors, while providing easier mounting and greater resistance to bending, the series will be employed in automotive buck/boost converters, battery packs and LED modules; EV charging infrastructure; inverters for windmills and solar panels; and office equipment.
Providing an SMD construction with NiSn terminations, the NTC thermistors are ideal for wave or reflow soldering. The devices are RoHS-compliant and halogen-free.
