Product Description
High-Performance Compact Common Mode Choke for Power Line Noise Filtering
The LFUR17 Series is a high-performance line of Common Mode Chokes designed for next-generation power electronics requiring efficient noise reduction and stable inductance. As a key component within the broader family of EMI Filters, RFI Filters, and LC Noise Suppression Filters, the LFUR17 Series offers a compact form factor with excellent electrical performance for a wide range of switching power supplies and consumer electronic devices.
Engineered with optimized magnetic core materials, the LFUR17 Series delivers high inductance with low resistance, allowing improved filtering efficiency without excessive power loss. The components support high pulse-handling capability and feature an industry-leading inductance/current ratio, ensuring reliable suppression of common-mode noise across a broad frequency spectrum.
These chokes are designed for wave soldering, offering ease of assembly and consistent thermal stability. With inductance options ranging from 3.3 mH to 100 mH, low DCR, and IDC ratings up to 2.5 A, the LFUR17 Series provides outstanding performance for AC/DC converters, LED ballasts, chargers, adapters, and other compact switching power systems.
Key Features
- High Inductance & Low DCR Ensures strong noise attenuation while minimizing power loss in switching circuits.
- High Pulse-Handling Capability Suitable for power converters operating under dynamic load conditions.
- Optimized for LC Noise Suppression Works seamlessly within EMI Filters and RFI Filters for superior EMC performance.
- Industry-Leading Inductance/Current Ratio Stable impedance characteristics across wide-band frequency ranges.
- Compact, SMD-Friendly Structure Designed for wave soldering and high-volume automated assembly.
- Reliable Temperature Performance Operating temperature: -40°C to +85°C Recommended not to exceed 125°C core temperature under worst-case conditions.
