VPG Foil Resistors 303143 Series of Ultra-High-Precision Resistors Now Available With S-311-P-813-Compliant “R” Screening Option to Reduce Time to Market
MALVERN, Pa. Sept. 08, 2015 — VPG Foil Resistors announced today that its Vishay Foil Resistors (VFR) brand’s 303143 Series of ultra-high-precision through-hole Z-Foil resistors is now available with an “R” screening option in compliance with NASA’s S-311-P-813 specification for leaded radial resistors. Offering a faster lead time to meet the market’s growing need for S-311-P-813-screened resistors in space system electronic circuits, devices ordered with the “R” option are submitted to the full test protocol (Group A, B, and C testing) for a shortened load-life testing period of 2,000 hours instead of 10,000 hours.
“The 303143 Series features the low TCR of Bulk Metal® Z-Foil technology in combination with the superior reliability provided by the S-311-P-813 screening method to deliver unmatched performance, lot-to-lot uniformity, and ultimately a higher level of reliability,” said Hero Faierstain, VFR Application Engineering Senior Manager. “As NASA continues to contract with third-party companies to develop electronics for use in space, the demand for resistors compliant to S-311-P-813 specifications will continue to increase. Not only are 303143 Series resistors the only such devices in the market to meet this demand, but the availability of the ‘R’ option greatly reduces the time to market as time needed for lot qualification is significantly shorter.”
303143 Series resistors feature low TCR of ±0.2 ppm/°C typical from –55°C to +125°C, 25°C ref.; tight tolerances to ±0.005%; and excellent load-life stability of ±0.005%. Optimized for critical avionics, military, and space (AMS) applications, the 303143 Series offers a resistance range from 10 Ω to 100 kΩ, with any conceivable ohmic value within this range — to six digits — available with no additional cost or lead time effect. The resistors feature rated power to 0.3 W at +125°C, a rise time of 1 ns with effectively no ringing, a thermal stabilization time of < 1 s (within 10 ppm of steady state value), current noise of ≤0.010 μVrms/V of applied voltage (< -40 dB), thermal EMF of 0.05 μV/°C typical, and a typical voltage coefficient of < 0.1 ppm/V.
Offering the utmost in ESD immunity, the devices withstand electrostatic discharges of at least 25 kV for increased reliability, and offer a non-inductive (< 0.08 μH), non-capacitive design. 303143 Series resistors provide drop-in replacements for previous-generation S102C/K devices, and matched sets are available upon request. Non-flight units are also available with the “U” option (100% Group A screening only).
