Overview
The Yageo MF-25-B metal film resistor is a through-hole component designed for general-purpose and precision circuits requiring stable, low-noise resistance values. Operating over a -55°C to +155°C temperature range with minimal drift, this 20kΩ resistor meets strict accuracy requirements in analog signal conditioning, biasing networks, and feedback circuits. The 1,000-piece bulk pack delivers cost-effective stocking for contract manufacturers and maintenance teams.
