The 03DPDG3S is a two-stage, general-purpose EMI filter designed to suppress unwanted electrical noise. It operates at a rated voltage of 115/250VAC, a frequency of 50/60Hz, and has a current rating of 3A. Key internal components include a C1 capacitance of 0.33 µF, C2 of 10 µF, and inductors L1 and L2 with values of 6.5 mH and 4.5 mH respectively. The filter is rated for a line-to-ground Hipot of 2250VDC and a line-to-line Hipot of 1450VDC. Its two-stage design provides high insertion loss for both common and differential mode emissions, making it effective for applications needing robust noise filtering.
