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

CRH2512F33R0E04Z is a standard part number in the CRH series of high-power thick film chip resistors from Ever Ohms Technology (EVER OHMS). This 2512 33R 2W resistor comes in a 2512 package (metric 6432, body size 6.35 × 3.20 × 0.55 mm), with a nominal resistance of 33Ω (33R), rated power 2W, tolerance ±1%, TCR ±100ppm/℃, and an operating temperature range of -55℃ to +155℃.

Data source:

The CRH series achieves 2W rated power in the standard 2512 footprint — twice the power of conventional 1W 2512 thick film resistors — by using a high-thermal-conductivity alumina ceramic substrate combined with ruthenium-based thick film resistor paste fired at 850℃.

• At 70℃, the resistor runs at full 2W. Above 70℃, power derates linearly to zero at 155℃
• For long-term reliability, keep continuous dissipation below 70% of rated power (≤1.4W)
• At 2W load, current ≈ 0.246A and voltage drop ≈ 8.1V — well within the 200V maximum working voltage
• Three-layer termination (Ag/Ni/Sn) is compatible with reflow and wave soldering

• Power supplies: SMPS RC snubber circuits, LED drive current limiting, DC-DC feedback dividers
• Industrial control: VFDs, servo drives for sampling and voltage division
• Consumer appliances: Air conditioners, refrigerators main control boards
• Telecom: Base station power, server power distribution
• Measurement: Electricity meters, navigation equipment signal conditioning

The LCSC catalog lists application fields as consumer appliances, household appliances (AC, fridge), computer motherboards, communication devices (mobile, fax), power equipment (power supply, lighting), and measurement instruments (meters, navigation).
