With a TCR (temperature coefficient of resistance) of only 25 ppm/K and tight tolerance options down to ±0.1% and ±0.5%, the new devices provide twice the power density of thin-film solutions.
Clara Lagomarsini, Product Manager of the Device Solutions Division at Panasonic Industry, explains: “Many applications—such as battery management systems (BMS), electronic control units (ECUs), household appliances, and industrial and manufacturing automation systems—require high-precision components. Our thick-film technology is a true alternative to thin-film implementations. The new ERJPC thick-film resistor series combines high precision and environmental stability, while offering a new path to long-term profitability.”
The ERJPC series thick-film resistors offer up to twice the power rating of thin-film resistors: 0.2 W in the 0603 size product and 0.25 W in the 0805 packaged units. This higher power density allows designers to replace thin-film components with smaller-case ERJPC resistors, saving up to 50% of space and significantly reducing costs.
Long-term stability is another common problem addressed by new devices. By combining high accuracy and low TCR, ERJPC thick-film resistors achieve significantly better overall tolerance than conventional thick-film resistors and approach the performance of thin-film resistors. Panasonic Industry has developed the new ERJPC series of high-precision thick-film resistors using advanced materials and optimized structures. The new series is manufactured with lead-free materials, making the ERJPC series RoHS compliant and consistent with Panasonic's global commitment to sustainability. The devices fully comply with the AEC-Q200 standard, enabling their use in automotive applications.
