Practical design notes for EV insulation monitoring, semiconductor ATE, ICT/PCB test, electrometer-grade low-leakage switching, hipot safety testers, medical equipment, PV inverters and battery-powered instruments.
Each note summarizes the application problem, switching topology considerations, candidate MiRelay product families and an engineering checklist. Values are guidance for selection only; final ratings must be confirmed against the exact product datasheet and the customer equipment validation plan.
Use high-insulation reed relays to connect, disconnect and verify insulation-monitoring paths without adding significant leakage or unstable capacitance to the measurement circuit.
Read application note →Reed and mercury-wetted reed relays can isolate high-voltage test resources while carrying controlled current pulses for power-device validation.
Read application note →Dense reed relay matrices support large ICT channel counts with fast switching, stable low-level signal behavior and long service life.
Read application note →High-insulation reed relays are preferred where switch leakage is comparable to the measured signal and where thermoelectric offsets must be controlled.
