Chip Resistors Set Stability Bar At ±0.0025%

The FRSM series Z1-Foil wrap-around chip resistors exhibit a load-life stability of ±0.0025% (25 ppm) at +70°C and typical TCRs of ±0.05 ppm/°C from 0°C to +60°C and ±0.2 ppm/°C from -55°C to +125°C, +25°C reference. With ESD protection of 25 kV and tolerances as low as 0.01%, six chip sizes are available from 0603 to 2512 with a resistance range from 5Ω to 125 kΩ. Other features include power ratings to 750 mW at +70°C, a rise time of 1.0 ns with effectively no ringing, thermal stabilization time of less than 1s, current noise of 0.010 μVrms/V of applied voltage (less than -40 dB), and a voltage coefficient of less than 0.1 ppm/V. Pricing starts at $4.32. VISHAY INTERTECHNOLOGY, INC., Malvern, PA. (619) 336-0860.
