MIL-PRF-83401-Qualified Single-in-Line Thin Film Resistor Network

Vishay Intertechnology, Inc. introduced a MIL-PRF-83401-qualified (cage code 57489) through-hole, single-in-line thin film resistor network. Featuring low absolute TCR of ± 25 ppm/°C, TCR tracking of 5 ppm/°C, and tight ratio tolerances to ± 0.05 %, the M83401 will outperform all the requirements of MIL-PRF-83401 R, V, and H characteristics. The resistor network released today offers three to nine resistors and is available in 6-, 8-, and 10-pin low-profile configurations in isolated (G) and pin one common (C) schematic styles. The type RZ070, RZ080, RZ090, RZ210, RZ220, and RZ230 device features 100 % burn-in screening for increased reliability in demanding military applications.

The M83401 features Vishay Dale Thin Film's patented SPM passivated Tamelox film for very low noise of < - 30 dB, voltage coefficient of < 0.1 ppm/V, power ratings from 0.06 mW to 0.120 mW per element (0.18 W to 1.0 W per package), and a wide resistance range of 100 ohms to 200 kohms per resistor. The device operates over a temperature range of - 55 °C to + 125 °C. Offering a low 4.95 mm (0.197 in) maximum seated height, the resistor network features a rugged, molded thermoset plastic construction with gold-plated copper alloy leads. The leads are attached to the metallized alumina substrates by thermocompression bonding. The M83401 is also available in a commercial version: the C83401.

Samples of the M83401 and C83401 resistor networks are available now. Production lead times are 12 to 14 weeks for standard orders. Pricing for U.S. delivery only starts at $4 to $5 per piece and varies by pin count.
