Panasonic Unveils Thick-Film Resistors with Thin-Film Precision and Higher Power Density

The Panasonic launch news: ERJPC high-precision thick-film resistors that deliver accuracy levels previously only achievable with thin-film technology, offering customers higher power density and cost-effective performance. With a TCR (Temperature Coefficient of Resistance) as low as 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 Device Solution Business Division at Panasonic Industry, explains: “Many applications - such as Battery Management Systems (BMS), Electronic Control Units (ECUs), home appliances, and industrial and factory automation systems - require high precision components. Our thick film technology is a real alternative to thin film implementations. The new ERJPC thick-film series combines high-precision, environmental stability, while offering a new path towards 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 the ERJPC series RoHS-compliant and aligned with Panasonic’s global commitment to sustainability. Devices are fully compliant with AEC-Q200, enabling them to be used in automotive applications.
