Thin Film Resistor Chips Offer T Reliability Level

Vishay extends its E/H MIL-PRF-55342-qualified thin-film, surface-mount resistor chips in the 0505, 1005, 1505, 0705, 1206, and 1010 case sizes to offer a "T" reliability level for space applications. Qualification on larger cases sizes is pending. The resistors were verified in qualification for the American Society for Testing and Materials (ASTM E-595) standard test method for total mass loss and collected volatile condensable materials from outgassing in a vacuum environment. Other features include a passivated Nichrome resistive element, power ratings to 500 mW, a noise figure of less than -25 dB, low voltage coefficient of less than 0.1 ppm/V, absolute TCRs down to ± 25 ppm/°C, tolerances down to 0.1 %, and a resistance range from 10 Ω to 1.69 MΩ depending on case size and characteristics. Pricing ranges from $5 to $15 per piece. VISHAY INTERTECHNOLOGY, INC., Malvern, PA. (619) 336-0860.
