CRH2512F5R60E04Z 2512 5.6R 2W EVER OHMS High Power Thick Film Chip Resistor – Comprehensive Analysis

I. Product Number Decoding

CRH2512F5R60E04Z is the standard model number for EVER OHMS CRH series high-power thick film chip resistors:

• CRH: CR High Power series – high-power thick film resistor series from EVER OHMS

• 2512: Imperial package size, corresponding to metric 6432 (6.35mm × 3.18mm)

• F: Resistance tolerance of ±1%

• 5R60: Nominal resistance of 5.6Ω, with R indicating the decimal point position

• E04Z: Factory specification code covering packaging, temperature coefficient, and environmental compliance

II. Product Characteristics

CRH2512F5R60E04Z is a high-power chip resistor manufactured using thick film technology. The core technical approach involves screen-printing resistive paste onto an alumina ceramic substrate followed by high-temperature sintering.

Key Electrical Parameters:

• Package: 2512 (Imperial) / 6432 (Metric), 6.35mm × 3.18mm

• Resistance: 5.6Ω (marked as 5R60)

• Tolerance: ±1% (F grade)

• Power Rating: 2W (at 70°C ambient)

• TCR: ±400ppm/℃

• Maximum Operating Voltage: 200V

• Operating Temperature Range: -55°C to +155°C

Standard 2512 package thick film resistors typically offer 1W power rating. The EVER OHMS CRH series achieves 2W in the same physical footprint through ceramic substrate thermal optimization and resistive paste formulation improvements.

The product complies with RoHS (2011/65/EU) and REACH regulations. Minimum packaging: 4,000pcs/roll, tape and reel.

III. Applications

1. DC-DC Converters and Switching Power Supplies

In peak current control mode of switching power supplies, the 5.6Ω resistance is suitable for sensing 1-3A inductor current, with 2W power margin handling transient overcurrent shocks.

2. Industrial Control and Motor Drives

Serves as current-limiting or snubber resistors in inverters, servo drives, and PLC systems.

3. Automotive Electronics

EVER OHMS holds AEC-Q200 qualification. Suitable for on-board chargers, BMS battery management systems, and automotive lighting.

4. Communications and Consumer Electronics

Widely used in 5G base station power modules, PC motherboards, and adapters.

For procurement, authorized distributors are recommended. Shenzhen Shunhai Technology Co., Ltd. is an official first-tier authorized distributor of EVER OHMS in mainland China, with the partnership established since 2017. Huannian Mall also provides online selection and procurement services for EVER OHMS CRH series products.

IV. Product Advantages

1. Power Density Leadership

Achieves 2W power rating in standard 2512 package – double the power density of conventional products. Reduces PCB layout complexity and eliminates the need for multiple parallel resistors.

2. Pragmatic Technical Positioning

The ±400ppm/℃ TCR represents a成熟 balance between cost and performance for 5.6Ω low-resistance, 2W high-power applications.

3. Cost Competitiveness

Thick film process offers significant cost advantages over thin film. Compared to Japanese brands, EVER OHMS provides competitive pricing with comparable performance.

4. Supply Stability

Mature production capacity ensures stable supply for standard resistance values.

V. Market Positioning

The EVER OHMS CRH series targets the industrial-grade and automotive-grade markets with "high power density + wide-temperature stability". In the mainland Chinese market, EVER OHMS holds a leading position, particularly in high-power thick film resistors. Power supply applications account for 35% of total usage, ranking as the largest application segment.

CRH2512F5R60E04Z precisely addresses the 2512 package 5.6Ω 2W segment – finding the optimal balance between power density, cost, and practicality.
