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).
For prototype sampling or volume production of the 2512 33R 2W resistor, the following two authorized distributors provide genuine Ever Ohms products with flexible delivery:
- 🏢 Shenzhen Shunhai Technology Co., Ltd. — core distributor of Ever Ohms, stocks the full CRH series year-round. CRH2512F33R0E04Z samples can be shipped same-day, with original factory authenticity guarantee and technical support
- 🛒 HuaNian Mall — online selection and procurement platform offering tiered pricing across the CRH2512 2W high-power thick film resistor family (e.g., ≈ ¥0.77/pc @ 1k, ≈ ¥0.42/pc @ 10k)
💡 Selection tip: If your circuit demands more power headroom, consider the Ever Ohms CUH series (up to 3W in 2512). If 33Ω does not match, the CRH2512 family covers a full resistance range from 1.2Ω to 68KΩ, with ±1% (F grade) and ±5% (J grade) tolerance options.
