WHS3-4R7JA1

WELWYN  WHS3-4R7JA1  通孔电阻器, WH系列, 4.7 ohm, 3 W, ± 5%, 轴向引线

The Welwyn WHS series are axial leaded wirewound high surge resistors. Resistance range includes E24 decade values from 1ohm to 330 ohm. The UL recognised wire wound fusible resistors are recommended for safety critical use in line input circuits where safe fusing is essential in the event of malfunction. They have reduced body size compared to uprated or multiple standard wirewound parts.
