■ Features ■ Applications ■ Model Designation ■ Rating High Power Low Resistance Chip Resistors HOKURIKU Specifications are subject to change without notice ・High power type, milliohm resistor product. Low resistance range covers from 10mΩ. ・Wide terminal made higher reliability of solder joint, compared to conventional chip resistor. ・Wide terminal made possible high power handling. (Rated power, WLCR64: 2W, WLCR50: 1W, WLCR32: 0.5W) ・High joint-strength against heat shock. ・Automotive electronics such as E.C.U., etc. ・Circuits requiring high resistance to vibration ・For current detection WLCR32 R 1 0 J V ①Model No. ②Resistance ③T o l e r a n c e ④Packaging (W) (%) (m Ω)( p p m / ℃) Voltage (V) Voltage (V) 10～33 ±500 36～91 ±350 100～910 ±200 F: ±1% 100 ～976 ±200 10～33 ±500 36～91 ±350 100～910 ±200 F: ±1% 100 ～976 ±200 10～33 ±500 36～91 ±350 100～910 ±200 F: ±1% 100 ～976 ±200 Operating Temperature Range : -55℃～＋155℃ 400WLCR64 2.0 J: ±5% 200 400 WLCR50 1.0 J: ±5% 200 400 WLCR32 0.5 J: ±5% 200 ①Model No. WLCR32 Symbol Tolerance(%) Symbol Packaging WLCR50 F ± 1.0 B Bulk WLCR64 J ± 5.0 V Paper taping (WLCR32) 10mΩ → R010 470mΩ → R47 102mΩ → R102 ③Tolerance ④Pckging 3 or 4 digit ②Resistance Embossed taping (WLCR50,WLCR64) (Example) E (Less than 100mΩ: all 4 digit Model No. WLCR32 WLCR50 WLCR64 Size Code INCH 1206 2010 2512 Size Code mm 3216 5025 6432
■ Dimensions ■ Structure ■ Surface Temperature For resistors operated in ambient temperature above70 ℃, power rating must be derated in accordance with the derating curve. ■ Surface Temperature Surface temperature rise is shown in this figure. Condition : Measured by soldering on glass cloth base material epoxy resin (t=1.6mm). ■ Packaging Refer "Dimension, Packaging, etc." HOKURIKU Specifications are subject to change without notice High Power Low Resistance Chip Resistors L c dW t Model No. L W c d t ＋0.15/-0.05 ② ③④⑤ ⑥ Symbol Material List ① Ceramic Substrate ② Conductor ③ Resistor ④ Over coat ⑤ Marking ⑥ Side Electrode 100 -55℃ 0℃ 70℃ 155℃ Power rating (%) Ambient Temperature(℃) 150 100 0 100 200 30050 Power rating (%) Surface temperature (℃) WLCR50WLCR64 WLCR32 Unit : mm
