CRM2512-FX-4422ELF is a high-power current sense chip resistor manufactured by Bourns using thick-film technology, designed for precision current sensing in power supplies, stepper motor drives, and snubber applications. The device features a power rating of 0.25 W at 70°C, an operating temperature range of -55°C to +155°C, and a resistance tolerance of ±1% with a temperature coefficient of ±100 PPM/°C. The resistor exhibits excellent stability under load life testing with less than 1% resistance change after 1000 hours at rated voltage, and maintains performance through thermal shock cycles with less than 0.5% resistance change. This RoHS-compliant component is ideal for applications requiring low-resistance values with high precision and reliability in demanding thermal environments.
