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
