MPMT1001AT5

MPMT1001AT5 Description

The MPMT1001AT5 from Vishay is a high-precision thin-film resistor network designed for demanding voltage division and signal conditioning applications. This dual-resistor network features two 500 Ω resistors with an ultra-tight tolerance of 0.1% and a low temperature coefficient of ±25 ppm/°C, ensuring stable performance across a wide temperature range of -55°C to +125°C. Encased in a molded SOT-23 package, it offers a compact footprint (3.05 mm × 2.5 mm × 1.12 mm) with gull-wing terminations for reliable surface-mount assembly. The device is rated for 0.2 W (1/5 W) total power dissipation and supports 100 V maximum voltage, making it suitable for precision analog circuits.
