CRH0805F9R10P05Z 0805 9.1Ω 0.25W Ever Ohms Resistor Specification

CRH0805F9R10P05Z is a standard part number of high-power thick film chip resistors from EVER OHMS CRH series. It adopts 0805 (metric 2012) package, with a nominal resistance of 9.1Ω, a resistance tolerance of ±1%, and a rated power of 0.25W at 70℃ ambient temperature. While maintaining the same PCB footprint as conventional 0805 chip resistors, this model doubles the power handling capacity compared with standard CR series of the same size, serving as a key component for high-power margin design in space-constrained circuits.

Technology and Performance Features

CRH0805F9R10P05Z is manufactured with mature thick film printing technology. Using high-purity alumina ceramic as the substrate, it goes through multiple processes including resistive paste deposition, high-temperature sintering, laser trimming, and terminal electrode plating. Compared with conventional thick film resistors of the same package, this model achieves doubled power density without expanding layout space by optimizing the resistive film formula and electrode structure, which reduces the number of power resistors required in the circuit and supports miniaturization design of end products.

This resistor features reliable temperature stability and pulse impact resistance, with an operating temperature range from -55℃ to +155℃, adapting to environmental requirements of both industrial and consumer products. Fully compliant with RoHS and REACH directives, it is produced with lead-free manufacturing process and compatible with lead-free reflow soldering, meeting the green compliance standards of the electronics manufacturing industry.
