CRH1206F4R70P05S 1206 4.7R 0.5W Ever Ohms Resistor Overview
Product Overview
The CRH1206F4R70P05S is a high-power thick film chip resistor from Ever Ohms, belonging to the CRH series. It comes in a 1206 imperial package (3216 metric) with a resistance of 4.7Ω (4.7R), ±1% tolerance, 0.5W rated power, and a temperature coefficient of ±400ppm/℃. In the 1206 footprint, standard thick film resistors typically offer 0.25W, while the CRH series doubles this to 0.5W through process optimization, delivering higher power density for space-constrained PCB designs.
Ever Ohms, founded in 1988, is one of the few manufacturers possessing thick film, thin film, and metal plate process technologies. The CRH series serves as its high-power thick film line, positioned above the standard CR series.

Technical Features
The primary advantage of the CRH series lies in its improved power density, achieved through optimized ceramic substrate thermal paths, resistor paste composition, and electrode heat dissipation structures. For the 1206 package, the 0.5W capability provides more headroom for derating in continuous power applications such as feedback dividers and current sensing. The thick film construction offers good thermal shock resistance, and the ±1% tolerance is suitable for circuits requiring consistent resistance values.
Applications
-
Secondary feedback dividers in switching power supplies
-
Current sensing front-ends with op-amp conditioning
-
Industrial control and DC-DC converters
-
Consumer electronics and communication equipment
Selection Notes
The ±400ppm/℃ TCR should be evaluated for precision or wide-temperature applications. Derating based on ambient temperature and thermal conditions is recommended for continuous 0.5W operation. When ordering, verify the "CRH" prefix in the part number to distinguish it from standard CR series resistors in the same package size.
