The CHP1206-JW-101ELF is an ultra-high power chip resistor from the Bourns CHP Series, engineered for demanding power applications requiring high surge withstanding capability. This 1206-size resistor features a power rating of 0.75 W at 70°C with a maximum working voltage of 250 V (for 1 ohm to 1 megohm range) and maximum overload voltage of 500 V, utilizing thick film technology on a ceramic substrate with nickel and tin plating for robust performance. The device operates across a wide temperature range of -55°C to +155°C with a temperature coefficient of ±100 ppm/°C (for 10 ohms to 1 megohm at ±1% tolerance), and is RoHS compliant and halogen-free. It is commonly used in power supplies, digital meters, consumer electronics, LED lighting, and industrial control boards where high power dissipation and reliability are essential.
