Ever Ohms CRH2512F4K70E04Z 2512 Chip Resistor 4.7KΩ 2W Rated Power ±1% Tolerance

2512 4.7K 2W Resistor Explained: Ever Ohms CRH2512F4K70E04Z High-Power Thick Film Chip Resistor

When you shop for passive components, the 2512 4.7K 2W resistor shows up often in power supplies, lighting, and industrial control boards. The part covered here, Ever Ohms CRH2512F4K70E04Z, belongs to the CRH series of high-power thick film chip resistors. It delivers 2W rated power in a 2512 package — twice what a standard 2512 thick film resistor can handle. This article walks through the part number, specs, applications, and market position.

Part number breakdown

CRH2512F4K70E04Z follows Ever Ohms naming rules in five sections:

• CRH: high-power thick film resistor series, with higher power density than the standard CR series;
• 2512: case size, 6.30 × 3.20 × 0.55 mm;
• F: ±1% resistance tolerance;
• 4K70: 4.7 kΩ, marked 4701 in the four-digit EIA code;
• E04Z: packaging and environmental code, embossed tape reel, lead-free, RoHS compliant.

So CRH2512F4K70E04Z is a 2512, 4.7 kΩ, 2 W, ±1% lead-free thick film resistor.

Key specs

Rated power is 2 W, maximum working voltage is 200 V, and the operating temperature range is −55 °C to +155 °C. At 4.7 kΩ the temperature coefficient is ±100 ppm/°C, so divider and sampling circuits stay stable under thermal drift. The thick film process, alumina ceramic substrate, and improved electrode structure open up the heat path — long-term reliability holds at full 2 W load. The part is RoHS and lead-free certified, so it fits directly into export-oriented designs.

Typical applications

The 2512 4.7K 2W resistor fits circuits that need both power and a small footprint:

• dummy loads, discharge resistors, and startup dividers in switch-mode power supplies;
• current limiting and sensing in LED drivers;
• precharge and bleed circuits in inverters and motor drives;
• power resistor slots in home appliances and power tool modules.

These boards are space-limited but run hot. A standard 2512 resistor at 1 W often leaves too little headroom; moving to the 2 W grade keeps the temperature rise in check and improves end-product reliability.

Why choose it

The value of CRH2512F4K70E04Z is simple: same footprint, double the power. You do not rework the layout or change the placement process — swap it in and the power margin goes up. Ever Ohms' mature supply chain keeps lead times short and batch consistency tight, and pricing sits in the mainstream range.

Market position and brand

Ever Ohms (天二科技) is a long-established Taiwanese chip resistor maker. The CRH series targets the mid-to-high-end high-power thick film segment, sitting between domestic commodity resistors and Japanese brands such as KOA and ROHM on price-performance. In power, lighting, and appliance supply chains, the CRH2512 is a common 2 W surface-mount resistor choice.
