SV275K10BL1 is a lead-style epoxy-coated square varistor from Bourns' SV Series designed for medium voltage transient protection. This device features a nominal voltage (Vn) of 430 V at 1 mA with a clamping voltage (Vc) of 680 V, providing robust protection for AC power networks and telecommunications applications. The varistor offers a maximum energy handling capability of 58 J (10/100 µs pulse), a maximum peak current of 3500 A (8/20 µs), and a typical capacitance of 500 pF at 1 kHz. With an operating temperature range of -40°C to +85°C, straight leads, and availability in bulk or tape-and-reel packaging, the SV275K10BL1 delivers high current and energy handling capabilities with low clamping voltage, making it ideal for protecting sensitive electronic equipment from transient overvoltages in power distribution and telecommunications systems.
