Des résistances à couche épaisse aussi précises que des modèles à couche mince
松下工业推出的ERJPC系列厚膜电阻，在精度上达到了与薄膜电阻相当的水平，同时功率密度提升一倍并降低了成本，为设计人员的小型化需求开辟了新可能。这一技术突破标志着厚膜电阻性能的显著提升。
传统上，薄膜电阻因其高精度和稳定性，常用于精密电路，但成本较高且功率密度有限。而厚膜电阻虽成本较低、功率处理能力较强，精度却通常不及薄膜电阻。ERJPC系列通过材料与工艺创新，成功融合了两者的优势。
该系列电阻的精度可达±0.5%，温度系数低至±50 ppm/°C，与许多薄膜电阻规格持平。其功率密度实现翻倍，有助于在更小空间内实现相同功耗，或同等体积下承载更高功率。成本方面，相比同精度薄膜电阻，ERJPC预计可降低约20-30%。
松下工业表示，此产品适用于电源管理、汽车电子、工业控制及测量设备等领域，尤其适合空间受限但要求高精度与高可靠性的应用。公司已开始提供样品，预计今年下半年量产。
业内专家认为，这一进展可能改变电阻市场的竞争格局，促使更多厂商研发高性能厚膜技术，并加速电子设备的小型化趋势。
Panasonic Industry has launched its ERJPC series of thick-film resistors, achieving precision levels comparable to thin-film resistors while doubling power density and reducing costs. This advancement offers designers new opportunities for miniaturization in electronic circuits.
The ERJPC series bridges a traditional performance gap: thick-film resistors are typically cost-effective and robust but less precise than thin-film alternatives. Panasonic's innovation lies in a refined thick-film material and manufacturing process that delivers a tolerance of ±0.5% and a temperature coefficient of resistance (TCR) of ±50 ppm/°C. These specifications match the precision of many standard thin-film resistors.
A key advantage is the doubled power density. For a given footprint, ERJPC resistors can handle approximately twice the power of conventional thick-film types, allowing for more compact power designs or improved thermal performance. Combined with the inherent cost benefits of thick-film production, this creates a compelling alternative for applications where space, power, and budget are constrained.
The series is initially available in the 0603 and 0805 case sizes, with resistance values ranging from 10 ohms to 1 megohm. Target applications include power supplies, automotive electronics, industrial controls, and consumer devices where reliable, precise resistance in a small package is critical.
By equating thick-film precision with thin-film standards while enhancing power handling, the ERJPC series provides a practical solution for engineers seeking to miniaturize designs without compromising performance or significantly increasing component costs.
