WS2M68R0J is a high surge withstand wirewound resistor from the Bourns WS Series, designed for applications requiring robust surge protection. This 2W resistor features a 68 O resistance value with 5% tolerance and a temperature coefficient of ±200 ppm/°C. It operates over a wide temperature range of -55°C to +200°C and is built on a low thermal resistant ceramic core with coating material meeting UL 94V-0 requirements. The resistor is designed to withstand surge conditions per IEC 61000-4-5 1.2/50 µs and has dimensions of 11.5 ± 1.0 mm (L) x 5.0 ± 1.0 mm (D). Common applications include smart meters, renewable energy systems, power supplies, chargers, and industrial equipment where surge withstand capability is critical.
