Metal thin film resistor networks
■ RM series
Features
Thin film surface
mount resistors
● Ultra accuracy: relative resistance tolerance +/-0.01%, relative TCR
+/-1ppm/°C
● Ultra reliability: 10,000 hours of 85°C/85RH test or 10,000 of 155°C high
temperature exposure test causes less than+/-0.1% resistance drift
Applications
RM series
● Applications that require a precise relative resistance ratio such as
voltage dividers, and gain-setting circuits for amplifiers.
