Metal thin film resistor networks
■
RM series
Features
●
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
Thin film surface
mount resistors
Applications
●
Applications that require a precise relative resistance ratio such as
voltage dividers, and gain-setting circuits for amplifiers.
