39KΩ Resistance High-Power Thick Film Chip Resistor
,2W Rated Power 2512 Chip Resistor
,±1% Tolerance CRH Series Resistor
CRH2512F39K0E04Z is a typical part number from Ever Ohms' CRH series high-power thick film chip resistors, specifying a 2512 package, 39KΩ resistance, ±1% tolerance, 2W rated power, and ±100PPM temperature coefficient. While standard 2512 thick film resistors are limited to 1W, this 2512 39K 2W resistor doubles the power density in the same footprint through optimized thick film paste and electrode structure — making it an ideal choice for power supply feedback, voltage divider sampling, and current limiting circuits that demand higher power margins.
- CRH: Ever Ohms high-power thick film chip resistor series code
- 2512: Imperial package size, metric 6.35×3.20mm
- F: Tolerance ±1% (F grade)
- 39K0: Nominal resistance 39KΩ
- E04Z: TCR ±100PPM/℃, Z denotes lead-free environmentally compliant tape packaging
Thus, the "2512 39K 2W" engineers refer to corresponds precisely to original part number CRH2512F39K0E04Z.

Standard 2512 thick film resistors are capped at 1W. The CRH series achieves 2W through:
- Upgraded thick film paste: Ruthenium oxide paste sintered at 850℃, thicker resistive layer, shorter thermal path
- Tri-layer electrodes: Silver/nickel/tin electroplating for superior thermal conduction and solder joint reliability
- Alumina ceramic substrate: Higher thermal conductivity than standard substrates, better temperature rise control
For the 39KΩ mid-high resistance value, 2W power means ample margin even at the 200V maximum working voltage. Even in 85℃ high-temperature environments, operating at 60% derating (≤1.2W), resistance drift remains well controlled — suitable for long-term full-load industrial power supplies and automotive electronics.
The 2512 39K 2W resistor combination of "mid-high resistance + high power margin" makes it common in:
- SMPS feedback networks: 39K is a standard pull-up divider value; 2W margin absorbs inrush surges, avoiding thermal failure of ordinary 1W parts
- Inverters & servo drives: Bleeder circuits, gate drive dividers
- Automotive BMS & on-board chargers: Bus voltage sensing, pre-charge current limiting
- Industrial PLC & telecom power: Signal division, pull-up/pull-down, buffering
- LED drivers & renewable energy inverters: Feedback compensation, voltage detection
💡 Selection tip: In high-temperature environments (>85℃), keep operating power below 60% of rated (i.e., ≤1.2W). Reserve ≥10mm² copper foil heat-sinking area at the pads and add 2-3 thermal vias.
