What is Precision Resistors?

Writer:Microhm Page View:Date:2018-06-04

Resistance tolerance, TCR, resistance components distribution and other indicators do not exceed a certain standard. When the resistance value is above 1Ω, tolerance is ±0.5% generally. When it below 1Ω, the tolerance is ±1% normally. The tolerance of Microhm's high precision resistors can be 0.05%, 0.1%.Precision resistors are widely used in aerospace, medical devices, automotive electronics, communication products and instrumentation because of their stable performance.


Standards of precision resistors:

1. High precision

2.Low TCR

3. Low parasitic parameter
