VIP4-2A-06(B042W0956) is a single-phase AC power EMI filter rated for 6A RMS current and 115/250VAC voltage, compatible with standard 50/60Hz mains power. It adopts a dual-stage circuit built with twin common-mode chokes and safety X/Y capacitors. The filter delivers strong suppression of common-mode and differential-mode conducted noise on AC input lines, helping electronic devices pass EMC tests such as EN55014 and GB9254. It features low leakage current, insulation resistance above 100MΩ and reliable high voltage withstand capability after one-minute hipot test. Its operating temperature covers -25℃ to +100℃, offering stable performance in various working environments. The product complies fully with RoHS and REACH environmental directives.

Purpose

This EMI power filter is used to purify the AC power input of electrical equipment. It isolates external electromagnetic interference from the power grid and restrains internal noise generated by the device from returning to the mains network. It effectively solves the problem of conducted interference exceeding limits, stabilizes power supply quality, prevents abnormal operation caused by power noise, and supports customers to complete EMC certification smoothly.

• Power supply products: AC-DC switching power supplies, industrial power supplies, battery chargers and power adapters
• Industrial control equipment: PLC controllers, servo drives, industrial measuring instruments
• Commercial electronic devices: office automation machines, security monitoring power supplies, LED lighting drivers
• Precision testing equipment: non-invasive auxiliary medical devices, laboratory measurement instruments

5 New EMI Filter FAQs

FAQ 1

Q: What is the difference between common mode noise and differential mode noise? A: Common mode noise appears on both power lines against ground, while differential mode noise exists between live and neutral lines. This filter can suppress both types of interference.

FAQ 2

Q: What will affect the filtering performance of this EMI filter? A: Installation layout, wire length, grounding condition and surrounding wiring will influence noise attenuation. Short ground wire and proper placement can maximize filtering effect.

FAQ 3

Q: Can this filter work continuously under full 6A rated current? A: Yes, it can run continuously at rated 6A RMS within the specified temperature range. Overload should be avoided to prevent overheating.

FAQ 4

Q: Why do we need to do hipot test for EMI filters? A: Hipot test verifies the dielectric strength of the filter. It ensures the insulation material can withstand high voltage and avoid electric safety risks during operation.

FAQ 5

Q: Does this EMI filter contain any restricted hazardous substances? A: No. All raw materials and components are carefully selected to satisfy RoHS and REACH requirements for global market sales.
