Vishay Intertechnology SMD Polymer PTC Thermistors Deliver Fast Resettable Overcurrent Protection While Improving Efficiency

MALVERN, Pa., June 30, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has extended its overcurrent protection portfolio with the introduction of six new surface-mount polymer positive temperature coefficient (PTC) thermistor series designed to save board space and increase efficiency in computer, industrial, and consumer applications.

The Vishay BCcomponents PPTC0603E3, PPTC0805E3, PPTC1206E3, PPTC1210E3, PPTC1812E3, and PPTC2920E3 series provide resettable overcurrent protection in low voltage circuits for computer USB-C ports; power over Ethernet (PoE) applications for computer peripherals and telecom equipment; battery-powered industrial tools and consumer devices and appliances; industrial automation systems; and home automation heating controls.

For these applications, the thermistors combine high holding current to 5.0 A with fast trip times down to 50 ms, while low resistance down to 5 mΩ reduces voltage drop and improves efficiency. To minimize board space requirements, the devices are offered in six compact case sizes from 0603 to 2920, with low heights ranging from 0.3 mm to 2 mm.

RoHS-compliant and halogen-free, the PPTC0603E3, PPTC0805E3, PPTC1206E3, PPTC1210E3, PPTC1812E3, and PPTC2920E3 series are compatible with lead (Pb)-free soldering processes up to 260 °C. SPICE and 3D models of the thermistors are available to support designers during development.
