CRH2512F33R0E04Z 2512 33R 2W Ever Ohms Resistor – Technical Overview

I. Product Overview

The CRH2512F33R0E04Z is a representative model from Ever Ohms Technology’s CRH series of high-power thick film chip resistors. Ever Ohms, established in 1988 and headquartered in Kaohsiung, Taiwan, is a specialized manufacturer of chip resistors and resistor arrays, certified to ISO-9001, IATF16949, and other international standards, with core products compliant to AEC-Q200 automotive grade requirements.

This model features a standard 2512 package (metric dimensions 6.35mm × 3.20mm), with a resistance of 33Ω (33R), tolerance of ±1%, rated power of 2W, and temperature coefficient of ±100ppm/℃. In the part number, “CRH” denotes the Ever Ohms high-power thick film chip resistor series, “2512” indicates the package size, “F” signifies ±1% tolerance, “33R0” represents 33Ω resistance, and “E04Z” corresponds to 2W power rating and tape packaging.

II. Key Technical Specifications

This 2512 33R 2W resistor operates across a temperature range of -55℃ to +155℃ with a working voltage of 200V, making it suitable for diverse temperature environments and voltage conditions. The product complies with EU RoHS Directive (2011/65/EU) and is free of REACH SVHC substances (1907/2006/EC).

III. Features and Core Advantages

1. High Power Density

The CRH2512F33R0E04Z delivers 2W rated power in a 2512 package, significantly outperforming conventional 1W thick film resistors in the same package size. This allows it to handle greater current loads within limited PCB area, making it ideal for high-power-density applications.

2. Excellent Temperature Stability

The ±100ppm/℃ low temperature coefficient ensures minimal resistance variation across a wide temperature range, guaranteeing circuit stability and consistency under varying operating conditions.

3. Wide Temperature Adaptability

The -55℃~+155℃ operating temperature range covers the vast majority of industrial and automotive electronics applications, maintaining stable performance even under high-low temperature cycling conditions.

4. High Reliability

Thick film technology combined with Ever Ohms’ stringent quality management systems ensures long-term stable operation. Ever Ohms is certified to ISO9001 and IATF16949 automotive quality management systems.

5. Environmental Compliance

The product complies with EU RoHS and REACH regulations, free of hazardous substances, meeting major global market environmental access standards.
