CRS0805-FW-1R00ELF is a high-power anti-surge chip resistor designed for pulse power and high-voltage applications. This 0805-sized resistor features a 1 O resistance value with ±1% tolerance and ±100 PPM/°C temperature coefficient, delivering 0.25 W power rating at 70°C with a maximum working voltage of 150 V and maximum overload voltage of 300 V. The device operates reliably across a wide temperature range from -55°C to +155°C and incorporates a lead-free tin-plated termination that is RoHS compliant. It is well-suited for telecommunications, power supplies, and consumer electronics applications where surge protection and thermal stability are critical performance requirements.
