Precision resistors offer high-temp stability

Precision resistors offer high-temp stability

The FRSM series ultra-high-precision Z1-Foil wraparound chip resistors offer a load-life stability of ±0.0025% (25 ppm) at 70°C and rated power for 2,000 hours. The resistors also provide stability of ±0.005% for 10,000 hours with low typical TCR of ±0.05 ppm/°C from 0° to 60°C and ±0.2 ppm/°C from –55° to 125°C, 25°C ref, a power TCR (ΔR due to self-heating) of 5 ppm at rated power, and tight tolerances to ±0.01%.

The noise-free devices come in six chip sizes from 0603 to 2512, have an ESD protection of 25 kV or more and feature a value range of 5 Ω to 125 kΩ. The resistors have power ratings to 750 mW at 70°C, a 1.0-ns rise time with effectively no ringing, a ≤1-s thermal stabilization time, current noise of 0.010 µVrms/V of applied voltage (≤–40 dB), and a voltage coefficient of ≤0.1 ppm/V.
