IV. Product Advantages
4.1 Leading Power Density
The most prominent advantage of this 2512 20K 2W resistor is its high power density. Standard 2512 package thick film resistors typically offer only 1W rated power. Through optimized thick film paste formulation, ceramic substrate thermal pathways, and multi-layer electrode structure design, the CRH series achieves 2W rated power—doubling the power capacity within the same package size.
For PCB designers, this means double the power handling capacity without increasing board area. It can directly replace two 1W resistors in parallel, saving approximately 50% of PCB space. The power density of this resistor’s resistive layer can reach 70W/cm².
4.2 Excellent Temperature Stability
This 2512 20K 2W resistor features a temperature coefficient of ±100ppm/℃, maintaining stable resistance across the wide temperature range of -55℃ to +155℃. Through thick film paste and electrode process optimization, the CRH series exhibits long-term resistance drift significantly lower than conventional CR series resistors.
4.3 High Reliability
EVER OHMS CRH series employs a metal-glaze thick film process with tin-nickel plated electrodes that enhance sulfurization resistance. The products demonstrate reliable performance under short-term overload, IR reflow soldering, and temperature cycling conditions. EVER OHMS has obtained ISO 9001 and IATF 16949 (automotive quality management system) certifications.
4.4 Cost Competitiveness
Thick film technology can reduce production costs by 40%–60% compared to thin film processes. The EVER OHMS CRH series achieves a balance of “automotive-grade reliability + thick film-level cost”, with bulk purchase costs offering significant advantages over comparable Japanese brands.
4.5 Environmental Compliance
The product complies with the EU RoHS Directive (2011/65/EU) and does not contain REACH SVHC substances.
