The new Panasonic ERJPC high precision thick-film resistors series 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 25ppm/K and tight tolerance options down to ±0.1% and ±0.5%, the new devices provide twice the power density than 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 combine 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 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.
