Vishay introduces new high-precision thin-film resistors

     Vishay Intertechnology introduces new high-precision thin-film resistors for industrial, medical, defense and aerospace applications. Compared to competing devices, the Vishay Sfernice P2TC has an extended resistance and temperature range, a TCR up to ± 2 ppm/C, multiple form factors and increased power ratings.

     The device includes five dimensions from 0402 to 2010, with resistance values of 100 W to 3.05 MW and tolerances as low as ± 0.01 %; Operating temperature -55°C to +155°C; Rated power up to 1 W. The resistance noise is lower than -35 dB, the voltage coefficient is less than 0.01 ppm/V, and the typical value of the resistance offset rate under the condition of +70 °C for 2,000 hours is ± 0.05%, which is better than the technical requirements of MIL-PRF-55342G.

     The P2TC is suitable for precision applications requiring low noise and high stability under time and temperature conditions. Final products include instruments, defense and avionics navigation systems, load sensors for weighing systems, and operational amplifiers for test and measurement equipment.
