CR0805-FX-51R1ELF is a thick film chip resistor from Bourns' CR Series designed for general-purpose and precision circuit applications. This 0805-format resistor features a resistance value of 51.1 O with ±1% tolerance, a maximum working voltage of 150 V, and a power rating of 1/8 W at 70 °C. The device operates reliably across a wide temperature range of -55 °C to +155 °C with a temperature coefficient of ±100 ppm/°C, and incorporates a three-layer termination process with nickel barrier for excellent solderability and leaching prevention. The resistor is RoHS compliant, available in paper tape and reel packaging (5,000 pcs per reel), and is well-suited for consumer electronics, industrial control systems, and precision measurement circuits where stable resistance and compact form factor are required.
