Wide Terminal Type Chip Resistor Hokuriku Electric Industry Co.,Ltd 【Model Number】 WECR**/WLCR**/WCR** 【Features】 ■Due to wide side terminal, high power handling was achieved. (Compared to same size other type, 1～2 higher rank is possible） possible） ■Due to high power capability, number of resistors, its occupied area can be reduced. ■Due to wide side terminal structure, solder joints hold high reliability. ■Wide side terminal structure has effect of suppressing heat generation. ■１０ｍΩ～１ＭΩ, wide resistance range is covered. ■Europe RoHS compliant product. 【Dimensions】 (Unit: mm) Model No. WECR32 WLCR32 WCR32 WECR50 WLCR50 WCR50 WECR64 WLCR64 WCR64 L W t c d 3.20±0.15 1.60±0.15 0.55 +0.15/-0.05 0.30±0.20 0.50±0.20 * (0.30±0.20) 5.00±0.20 2.50±0.20 0.56±0.15 0.50±0.20 0.60±0.20 * (0.50±0.20) 6.30±0.20 3.20±0.20 0.56±0.15 0.50±0.20 * (0.60±0.20) 0.90±0.20 * (0.60±0.20) *: Dimensions in ( ) are of WECR series. 【Designation】 WCR３２ ① ①Model No. Model No. Size WECR32 1632 WECR50 2550 WECR64 3264 WLCR32 1632 WLCR50 2550 WLCR64 3264 WCR32 1632 WCR50 2550 WCR64 3264 - １０３ ② Ｊ ③ Ｖ ④ ②Resistance Value Marking Resistance 103 10KΩ 103＝10×10 ３ ＝10,000Ω＝10KΩ ③Resistance Tolerance Symbol Tolerance Ｆ ±1.0％ J ±5.0％ R10＝0.10Ω R is decimal point. * Design・specification are subject to change without prior notice.
