VIP4‑1A‑06(B041Q0832) is a single‑phase chassis‑mounted EMI power filter developed for hardware engineers to solve conducted emission and ground‑leakage trade‑off challenges. Rated at 6A RMS for 115/250VAC 50/60Hz mains input, this single‑stage LC filter integrates common‑mode choke, X‑capacitor and low‑value Y‑capacitors. The optimized Y‑cap configuration achieves ultra‑low line‑to‑ground leakage current while maintaining adequate noise attenuation performance for both common‑mode and differential‑mode interference.

      The compact metal shielded case reduces external electromagnetic coupling to adjacent PCBA and wiring inside the enclosure. High insulation resistance and wide temperature scope guarantee stable electrical parameters under variable load and thermal conditions.

Highlights

‑ Carefully tuned LC circuit design, balances EMI filtering performance and ground‑leakage current for engineering‑level trade‑off
‑ 6A RMS continuous current rating, compatible with global single‑phase 115/250VAC 50/60Hz power grid
‑ Ultra‑low leakage current: max 0.3 mA @115VAC/60Hz; max 0.6 mA @250VAC/50Hz, reduces risk of ground‑fault tripping in end systems
‑ Single‑stage topology suppresses both common‑mode and differential‑mode AC‑line conducted noise
‑ Miniature metal shield housing, minimizes electromagnetic crosstalk to nearby sensitive circuits
‑ Insulation resistance ≥100 MΩ @500VDC, ensures dielectric safety for long‑time running equipment
‑ Operating temperature: ‑25℃ ~ +100℃, electrical characteristics remain consistent under thermal variation

Application

‑ R&D projects where ground‑fault protection or leakage‑current limitation is critical design index
‑ Electronic devices with high‑sensitivity PCB circuits vulnerable to power‑line EMI crosstalk
‑ New product schematic evaluation, prototype verification and pre‑compliance EMC lab testing
‑ Compact industrial control boards and embedded systems with limited internal installation space
‑ Power input filtering for instruments that cannot tolerate high ground leakage current
‑ Hardware comparative selection between different EMI filter models
