- E04Z: Power rating and packaging code, corresponding to 2W
Based on EVER OHMS official CRH series datasheet:
| Parameter | Specification |
|---|---|
| Brand | EVER OHMS |
| Type | High-power thick film chip resistor |
| Package | 2512 (6.3 × 3.2 × 0.65 mm) |
| Resistance | 33 kΩ |
| Tolerance | ±1% (F grade) |
| Rated Power | 2W (at 70℃ ambient) |
| TCR | ±100 ppm/℃ |
| Operating Temp. | -55℃ to +155℃ |

The 2W rated power is defined under 70℃ continuous full-load conditions. Above 70℃, power must be derated linearly according to the manufacturer's derating curve, reaching 0% at 155℃.
The CRH2512F33K0E04Z 2512 33K 2W resistor employs:
- Substrate: High-purity alumina ceramic for superior thermal conductivity
- Resistive element: Ruthenium-based thick film paste, sintered at 850℃
- Terminations: Multi-layer copper alloy with tin plating, sulfur-resistant
- Protection: Glass釉 coating against moisture and dust
Compared to standard CR series resistors of the same footprint, the CRH series delivers 30%~50% higher power capacity, achieving 2W in a 2512 package and eliminating the need for parallel resistor arrays.
Per datasheet formula E = √(P × R):
For 33 kΩ / 2W: E = √(2 × 33000) ≈ 257 V. Both the power limit and voltage limit must be observed in circuit design.
- Power supplies & DC-DC converters: Feedback divider, current limiting
- Battery Management Systems (BMS): Balancing resistors, sense dividers
- Industrial control: PLC input dividers, signal conditioning
- Automotive electronics: AEC-Q200 compliant grades available
- Telecom equipment: Bias circuits for RF power amplifiers
At 33 kΩ with 2W rating, a single resistor can sustain approximately 7.8 mA continuous current, suitable for most medium-high voltage divider and buffer stages.
