Product Number Interpretation
CRH2512J18R0E04Z is the complete model number of the high-power thick film chip resistor from EVER OHMS (Tian'er Technology) under the CRH series. "CRH" represents the power-enhanced thick film resistor series, which improves power rating compared to the original CR series; "2512" indicates the package size; "J" denotes ±5% tolerance; "18R0" signifies 18Ω resistance; "E04Z" relates to packaging or series subdivision.
Product Characteristics
Key parameters of the CRH2512J18R0E04Z 2512 18R 2W resistor:
- Type: Thick film resistor
- Package: 2512
- Resistance: 18Ω
- Tolerance: ±5%
- Power Rating: 2W
- Operating Voltage: 200V
- Temperature Coefficient: ±100ppm/℃
- Operating Temperature: -55℃~+155℃
The most notable feature is its power density. Standard 2512 package resistors typically offer 1W or 0.75W, while this component achieves 2W within the same footprint. The ±100ppm/℃ TCR ensures stable resistance across the -55℃ to +155℃ range.
Applications
Based on its high voltage and temperature resistance, the CRH2512J18R0E04Z 2512 18R 2W resistor is widely used in switching power supply snubber circuits, industrial frequency converter braking circuits, high-brightness LED driver boards, automotive electronics and BMS systems, DC-DC converters and power modules, as well as telecom base station and server power supplies.
