VIP1-1B-03(B011X0423) Product Introduction

VIP1-1B-03(B011X0423) is a single stage single phase AC EMI power filter with rated 3A RMS current and 115/250VAC rated voltage for 50/60Hz mains power. It adopts an optimized single stage filtering circuit and achieves ultra low leakage current performance with maximum value of 2uA at 115VAC 60Hz and 5uA at 250VAC 50Hz, making it well suited for medical and precision electronic equipment. This filter passes one minute high voltage hipot test including 2000VAC line to ground and 500VDC line to line. Its insulation resistance exceeds 100M ohm under 500VDC. It can operate stably within temperature range from minus 25 degree Celsius to plus 100 degree Celsius and provides good common mode noise attenuation in the 50 ohm test system. The product meets RoHS and REACH environmental requirements and helps end products fulfill EMC compliance requirements.

Purpose

This AC EMI power filter is installed at the AC power inlet of electronic devices to purify the input power. It suppresses common mode and differential mode conducted electromagnetic interference on power lines bidirectionally. It blocks external noise from power grid entering sensitive equipment and prevents internal switching noise of the device from feeding back to the mains. It effectively reduces power line interference and helps equipment pass EMC related certification tests to guarantee stable and safe operation.

Application Range

• Medical and monitoring equipment: patient monitors, portable diagnostic devices and other medical precision instruments
• Laboratory measuring instruments and analytical test equipment
• Industrial automation control devices and small power industrial power supplies
• Precision household appliances and office automation equipment
• Low power LED drivers and security monitoring power supply modules

5 General FAQs for EMI Filters

FAQ 1

Q: What is leakage current of EMI filter and why ultra low leakage current matters for medical devices A: Leakage current refers to the tiny current flowing from circuit to ground. For medical equipment contacting human body ultra low leakage current avoids electric shock risk and satisfies strict medical safety standards.

FAQ 2

Q: What is hipot test for power EMI filter A: Hipot test is high voltage safety test to verify dielectric strength of filter insulation material. This model can withstand 2000VAC line to ground and 500VDC line to ground for one minute without breakdown.

FAQ 3

Q: What is insertion loss of EMI filter A: Insertion loss represents the noise attenuation capacity of filter. Higher dB value means better suppression effect on high frequency electromagnetic noise on AC power lines.

FAQ 4

Q: Can this EMI filter work for both 50Hz and 60Hz power grids A: Yes this filter is designed for 50 60Hz AC mains supply and can be used for power systems of different countries and regions worldwide.

FAQ 5

Q: What factors will reduce EMI filter filtering performance A: Improper installation including long input output cable poor grounding and bundled input output wires will greatly weaken noise suppression effect of the EMI filter.
