Panasonic’s new ERJPC high-precision thick-film resistors achieve accuracy levels that were once only possible with thin-film technology, delivering both higher power density and cost-effective performance. With a temperature coefficient of resistance (TCR) as low as 25 ppm/K and tight tolerances of ±0.1% and ±0.5%, these resistors offer twice the power density of comparable thin-film solutions.
Clara Lagomarsini, Product Manager of the Device Solution Business Division at Panasonic Industry, says: “Applications like Battery Management Systems (BMS), Electronic Control Units (ECUs), home appliances, and industrial automation demand high-precision components. Our thick-film technology provides a compelling alternative to thin-film designs, combining precision, environmental stability, and long-term cost efficiency.”
ERJPC series thick film resistors feature up to twice the power rating of thin film resistors – 0.2W in the 0603 case size product and 0.25W in the 0805 packaged units. This higher power density enables designers to replace thin-film components with smaller-case ERJPC resistors, saving up to 50% footprint while significantly reducing costs. Long-term stability is another common issue that the new devices address. By combining high accuracy and low TCR, ERJPC thick film resistors achieve a total tolerance that is significantly better than conventional thick film resistors and approaches thin film level performance.
Panasonic Industry has developed the new ERJPC series of thick-film high-precision resistors by using advanced materials and optimized structures. The new series is manufactured with lead-free materials, making ERJPC series RoHS-compliant and aligned with Panasonic’s global commitment to sustainability. Devices are fully compliant to AEC-Q200, enabling them to be used in automotive applications.
