Product Overview
Precision Metal Film Resistors are high-performance resistive components designed for high-precision and high-stability circuits.
This series of products utilizes advanced vacuum deposition technology to form a uniform metal film layer on a high-purity ceramic substrate, thereby achieving extremely low temperature coefficients (25ppm, 50ppm, 100ppm) and high-precision resistance tolerances (±0.25%, ±0.5%, ±1%, ±5%).
These resistors possess excellent temperature stability and low noise characteristics, maintaining outstanding electrical performance even in harsh operating environments, making them ideal for instrumentation, precision control, and measurement circuits.
