Vishay Intertechnology Thin Film Wraparound Chip Resistor Offers Power to 1 W, Resistance From 39 Ω to 900 kΩ in Four Small Case Sizes

Available in Case Sizes From 0402 to 1206, High Precision Device Enables Miniaturization and Increases Reliability

MALVERN, Pa. — May 16, 2022 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new high precision thin film wraparound chip resistor for industrial, military, and aerospace applications. In addition to offering the widest resistance value range on the market, the Vishay Sfernice PEP delivers higher power ratings in smaller case sizes than competing devices, which enables miniaturization and increases reliability by reducing the mechanical stress on solder joints.

The resistor released today is available in four case sizes from 0402 to 1206 and features a high power rating to 1 W in the 1206 case size (without cooling under the PCB). The PEP offers a wide resistance range from 39 Ω to 900 kΩ, with tolerances down to ± 0.05 %, and operates over a broad temperature range of -55 °C to +155 °C. Combined with very low noise of < -35 dB, a low voltage coefficient of < 0.01 ppm/V, and load-life stability of ± 0.1 % typical for 2,000 hours at +70 °C, the device’s typical specifications exceed the requirements of MIL-PRF-55342G.

The PEP is optimized for precision applications requiring low noise and high stability over time and temperature. End products will include instrumentation, military and avionics guidance systems, automatic test equipment, industrial appliances, and operational amplifiers for test and measurement equipment.

RoHS-compliant, halogen-free, and Vishay Green, the device is sulfur-resistant per the ASTM B809-95 humid vapor test.

Why Measure C02 Indoor Air Quality?

Sponsored by Mouser Electronics and Sensirion

The amount of carbon dioxide in the air can be a key indicator in indoor air quality and improving our indoor air quality can have a slew of benefits including increased energy efficiency, increased cognitive performance, and also the reduction of the risk for viral infection. In this episode of Chalk Talk, Amelia Dalton chats with Bernd Zimmermann from Sensirion about the reasons for measuring carbon dioxide in our indoor spaces, what this kind of measurement looks like, and why Sensirion’s new SCD4 carbon dioxide sensors are breaking new ground in this arena.
