Devices Offer Lower R25 Values of 1 kΩ and 1.5 kΩ, in Addition to a 5 kΩ Value for IGBT and Power MOSFET Modules in EVs and HEVs
MALVERN, Pa., April 11, 2022 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it 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 +25 °C (R25). The AEC-Q200 qualified devices are now available with lower R25 values of 1 kΩ and 1.5 kΩ, in addition to a new 5 kΩ value optimized for the protection of IGBT and power MOSFET modules in electric (EV) and hybrid electric (HEV) vehicles.
Fully glass coated and protected, the enhanced thermistors offer tolerances down to ± 1 % for both their R25 and beta (B25/85) values for precise temperature sensing, protection, and compensation over a wide temperature range of -40 °C to +150 °C. Smaller than MELF resistors, while offering easier mounting and greater resistance to bending, the NTCS0603E3.....T and NTCS0805E3.....T series will be used in automotive buck / boost converters, LED modules, and battery packs; EV charging infrastructure; inverters for windmills and solar panels; and office equipment.
Featuring an SMD construction with NiSn terminations, the NTC thermistors are suitable for wave or reflow soldering. RoHS-compliant and halogen-free, the devices are delivered on punched paper tape on reels in packages of 4,000 units.
