CRS2010-FX-1000ELF is a high-power anti-surge chip resistor designed for pulse power applications, high-voltage applications, consumer electronics, telecommunications, and power supplies. The device features a 1 W power rating at 70°C, a maximum working voltage of 200 V, and a maximum overload voltage of 400 V, with an operating temperature range of -55°C to +155°C. It incorporates a resistive element on a ceramic substrate with tin-plated lead-free termination, providing RoHS compliance and excellent surge performance. The resistor exhibits superior reliability under thermal cycling and load-life conditions, with resistance change specifications of ±(1% + 0.05 O) after temperature cycling and ±(3% + 0.1 O) after 1000 hours of load life testing. This combination of high power handling, surge protection, and thermal stability makes it ideal for demanding applications requiring robust pulse power management and high-voltage circuit protection.
