What are DCR (Dynamic Contact Resistance) and SCR (Static Contact Resistance), and why does TOWARD measure its value during testing? - FAQs | Bright Toward Industrial Co., LTD.

To ensure a stable resistance throughout the operation of TOWARD’s Reed Relays, not only do we measure the resistance value when the relay is entirely on, but we also measure its dynamic contact resistance (DCR) and static contact resistance (SCR). Dynamic contact resistance refers to the variation in contact resistance during the period in which contacts closed but have not reached a stable point and are still in motion; in other words, the resistance value when the contacts are still bouncing after closing. Static contact resistance (SCR) refers to the resistance value after stable contact closure is achieved. Manufacturer of Opto-MOSFET Solid State Relays, Reed Relays, and RF MEMS Switches. We mainly serve the Semiconductor Testing, ATE, BMS (Battery Management Systems), industrial machinery and Electric Vehicle industries.
