Product Description

FERRTX's LFU series common mode inductors are engineered to effectively eliminate electromagnetic interference (EMI) and ensure compliance with global EMC standards like FCC and CISPR. These versatile noise suppression components combine high isolation voltage with an advanced magnetic design to suppress both common-mode (CM) and differential-mode (DM) noise in a single compact package.

Technical Advantages & Features

Dual-Mode Noise Suppression: Effectively mitigates both CM and DM noise, ensuring clean power delivery and regulatory compliance.
High Isolation Voltage: Withstands up to 2500VAC between windings (LFUR17 series), ensuring reliability and safety in high-noise environments.
High Current Ratings: Support applications from 0.3A to 3.0A across the series, suitable for a wide range of power levels.
Low Resistance & Temperature Rise: Optimized windings ensure high efficiency and minimal energy loss.
Robust Construction: Excellent mechanical strength and wave soldering compatibility for reliable PCB mounting.
Wide Operating Temperature Range: Stable performance from -50°C to +110°C (LFU26/28).

Applications

Our common mode chokes are ideal for:

Switch-Mode Power Supplies (SMPS): Especially in 100W to 500W range for consumer and industrial electronics.
LED Lighting Drivers: Enhances reliability and eliminates flicker in LED power supplies and ballasts.
EMI/EMC Filters: Serves as a core component in filter designs to meet stringent electromagnetic compatibility requirements.
