33 kΩ 2W High Power Thick Film Chip Resistor with ±1% Tolerance in 2512 Package

CRH2512F33K0E04Z is a 2512 33K 2W resistor from the CRH series of EVER OHMS (Tian Er Technology). It belongs to the high-power thick film chip resistor family, designed for applications that demand high power dissipation in a compact SMD footprint.

• CRH: High-power thick film chip resistor series
• 2512: EIA package size (metric 6432)
• F: Resistance tolerance ±1%
• 33K0: Nominal resistance 33 kΩ
• E04Z: Power rating and packaging code, corresponding to 2W

Based on EVER OHMS official CRH series datasheet:

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.
