Anti-surge resistors with high ESD tolerance

October 13, 2015 // By Graham Prophet
Panasonic Automotive & Industrial Systems’ anti-surge resistors feature capacitive-coupled isolation for high-temperature and small size requirements: in an 0402 case size and with rated power of 0.2W, ERJ-PA2 series resistors offer space savings without compromising on rated power specifications.

ESD voltage of 3.0 kV provides very high circuit reliability. A TCR of 100 ppm and a tolerance of down to ±0.5% result in very stable resistance and circuit operation. Panasonic adds that, “the ERJ-PA2 series anti-surge resistors use a metal glaze thick film resistive element and three layers of electrodes making them very reliable. The ESD surge characteristics of the products are superior to standard metal film resistors.” They are rated for -55°C up to +155°C for use in automotive/transportation applications, industrial electronics, as well as consumer electronics.
