Technical Characteristics & Applications
In a 2512 package, standard chip resistors typically offer 1W power rating. The CRH2512F4R70E04S doubles this to 2W. For a 4.7Ω resistor, 2W power rating translates to approximately 0.65A continuous current capability – about 40% higher than standard 1W resistors (≈0.46A). This makes it suitable for power supply input stages handling surge currents, DC-DC converters, LED drivers, and motor control boards.
The resistor utilizes thick film technology with an alumina ceramic substrate and a resistive element made from ruthenium and glass paste sintered at high temperatures. The TCR of ±400ppm/℃ reflects a practical design approach for high-power applications where the resistor operates under elevated temperatures.
Model Number Decoding
Ever Ohms follows a structured naming convention:
