High Power Type Wide Terminal Ultralow Resistance Chip Hokuriku Electric Industry Co.,Ltd [Model No.] WECR** [Features] ■As a ultralow resistor of starting from 5mΩ, this is excellent for current detection application. WECR32 ■By using resistor material of excellent temperature characteristic, TCR ±100ppm/℃ 100ppm/℃ is achieved in full range of 5mΩ～ mΩ～91mΩ 91mΩ WECR50 ■Synergy effect of double side resistor and wide side terminal structure suppresses heat generation from resistor element, making high power handling possible. WECR64 ■Due to wide side terminal structure, solder joints hold high reliability. ■Europe RoHS compliant product.
