High-Precision Thin Film Wraparound P2TC Chip Resistor for High Stability in Low Noise and Precision Applications
Vishay Sfernice P2TC is the latest high-precision thin-film wraparound chip resistor released by Vishay Intertechnology for industrial, medical, military, and aerospace applications. With a tight TCR of ± 2 ppm/°C over wider resistance and temperature ranges, this new device is available in five case sizes from 0402 to 2010 with higher power ratings compared to the competing devices.
The device offers a wide resistance range of 100 Ω to 3.05 MΩ with tolerances down to ± 0.01%; operates over a broad temperature range of -55 °C to +155 °C; and offers a high power-rating to 1 W. Combined with very low noise of < -35 dB, a low voltage coefficient of < 0.01 ppm/V, and load-life stability of ± 0.05% typical for 2,000 hours at +70 °C, the resistor’s specifications exceed the requirements of MIL-PRF-55342G.
Optimized for precision applications requiring low noise and high stability over time and temperature, the P2TC helps in instrumentation, military and avionics guidance systems, load cell electronics in weighing systems, and operational amplifiers for test and measurement equipment. The device is RoHS-compliant, halogen-free, Vishay Green, and sulfur-resistant per the ASTM B809-95 humid vapor test. The samples and production quantities of the P2TC resistor are available from the company websites and come with lead times of 16 weeks.
