The ERJP series offers high-power and anti-surge chip resistors. Panasonic designed the serpentine pattern of the resistive element to decrease electric field strength per unit length and to disperse heat. Panasonic also developed the resistive paste that is superior for surge, pulse, and ESD tolerance characteristics. The ERJP series offers twice the power rating of conventional chip resistors at equal case size. And this product has higher pulse and ESD tolerance.
