The 03NB4 is a power entry module that combines an IEC connector, a double fuse holder, and an EMI filter into one compact, easy-to-install unit. It is rated for a current of 3A at both 115VAC and 250VAC, operating at a frequency of 50/60Hz. This model is designed without a power switch and features an inductance (L) of 2.5 mH, a line-to-line capacitance (Cx) of 0.1 uF, and line-to-ground capacitance (Cy) of 2200 pF. With UL, CSA, and VDE approvals, the 03NB4 provides effective EMI filtering for a wide range of electronic equipment.
