High precision thin film wraparound chip resistor delivers tight TCR

Vishay Intertechnology has launched a new high precision thin film wraparound chip resistor for industrial, medical, defence, and aerospace applications. The Vishay Sfernice P2TC provides a tight TCR of ±2ppm/C over more extensive resistance and temperature ranges — and in more case sizes with higher power ratings — than comparable devices.

Offered in five case sizes from 0402 to 2010, the device offers a wide resistance range of 100Ohm to 3.05MOhm, with tolerances down to ±0.01%; operates over a wide temperature range of -55C to +155C; and provides a high power rating to 1W. Together with very low noise of <-35dB, a low voltage coefficient of <0.01ppm/V, and load-life stability of ±0.05% typical for 2,000 hours at +70C, the resistor's specifications exceed the requirements of MIL-PRF-55342G.

The device is optimised for precision applications needing low noise and high stability over time and temperature. End products will incorporate instrumentation, defence and avionics guidance systems, load cell electronics in weighing systems, and operational amplifiers for test and measurement equipment.

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