VIP4‑1B‑20 EMI Power Line Filter 20A 115‑250VAC Terminal Block Connection Common‑Mode Differential‑Mode Noise Filter For Sensitive AC Equipment

Product Overview

VIIP VIP4‑1B‑20 B041T1252 Single‑Phase AC EMI Power Line Filter

VIP4-1B-20 (B041T1252) Terminal Mount EMI Power Filter. High quality EMI filter with 20A 115/250VAC single phase EMC power line filtering for AC power supply systems.

The Single Phase EMI Filter is a high-performance AC filter engineered to suppress electromagnetic interference in single-phase power systems. Rated at 115/250VAC and 50/60Hz with a robust 20A current capacity, it features exceptionally low leakage current (max 0.6mA) for enhanced safety and efficiency. RoHS compliant and free from hazardous substances, it delivers reliable high-frequency noise attenuation to protect connected devices from malfunctions and EMI-induced damage.

Its compact, terminal-mount design ensures easy integration into industrial machinery, automation equipment, and power supply units—making it a dependable choice for improving EMC performance and system stability across a wide operating temperature range of -25°C to +100°C.

Frequently Asked Questions

Q1: Do you supply samples of VIP4-1B-20 terminal block EMI filter for our EMC performance test?

Yes, we can provide VIP4-1B-20 samples for customer EMC testing.

Q2: What environmental compliance certificates does VIP4-1B-20 power filter have? Does your factory pass ISO9001 certification?

Our VIP4-1B-20 EMI filter fully complies with RoHS & REACH standards for global export. Our manufacturing factory holds ISO9001 quality management certification, all products pass complete internal safety tests and we can offer official certification documents upon request.

Q3: What are the rated voltage, rated current and leakage current parameters of VIP4-1B-20 single-phase filter?

Rated voltage: 115/250VAC, max 20A RMS at 115VAC; Operating frequency 50/60Hz. Max leakage current 0.3mA@115VAC/60Hz, 0.6mA@250VAC/50Hz, suitable for most industrial automation equipment.

Q4: What's the hipot test and insulation resistance standard of VIP4-1B-20? How about its common & differential mode insertion loss?

The filter withstands 1-minute high-pot test; insulation resistance ≥100MΩ under 500VDC between input/output and ground. It achieves excellent insertion loss in 0.15~30MHz under 50Ohm system, effectively suppressing both common mode and differential mode power interference.

Q5: Do you only make terminal block type filters? What other installation styles of EMI filters do you produce?

Besides terminal block type, we manufacture IEC socket, DIN rail mounted, bolt connection and wire lead EMI power filters.
