CRS0805-FX-1001ELF is a high-power anti-surge chip resistor designed for pulse power and high-voltage applications. It features a 0.25 W power rating at 70°C, a maximum working voltage of 150 V, and a maximum overload voltage of 300 V, with an operating temperature range of -55°C to +155°C. The resistor offers a resistance value of 100 ohms (1001 in the part number represents 100 × 10¹ ohms) with ±1% tolerance and ±100 PPM/°C temperature coefficient. Its compact 0805 form factor (2.00 × 1.25 mm) and lead-free tin-plated termination make it suitable for consumer electronics, telecommunications, and power supply applications where surge protection and reliability are critical.
