The ESR25 is a 1/4 anti-surge thick film chip resistor with a power rating of 1/2W (MCR25 1/4W). It offers superior anti-surge performance compared to the MCR series. The resistor features a highly reliable ruthenium oxide dielectric that provides resistance to the elements. It is approved by ISO-9001 and ISO/TS 16949 certification and complies with the RoHS directive. The ESR25 resistor is suitable for automotive, LCD monitor, projector, power supply, charger, inverter, and other applications.
