CRS2512-FX-1002ELF is a high-power anti-surge chip resistor from the Bourns CRS Series designed for demanding pulse power and high-voltage applications. This 2512-size resistor delivers 2 W power rating at 70°C with a maximum working voltage of 300 V and maximum overload voltage of 600 V, making it suitable for telecommunications, power supplies, and consumer electronics. The device features a wide resistance range from 1 ohm to 1 megohm with ±100 PPM/°C temperature coefficient and ±1% tolerance, operating reliably across -55°C to +155°C. Its compact dimensions (6.40 × 3.20 × 0.60 mm) and RoHS-compliant tin-plated termination enable easy integration into modern PCB designs. The anti-surge construction provides excellent protection against transient voltage spikes, making it ideal for power management circuits and surge protection applications.
