BLF082

Overview

The BLF082 is a two-channel LC EMI filter manufactured by TE Connectivity Corcom Filters. It features an inductance of 2µH and capacitance of 82pF per channel, rated for a current of 2.2 A. The component utilizes surface mount technology (SMD) packaging. Rated voltage specifications indicate operation at 56.6 VAC or equivalent DC levels. Attenuation performance reaches 20dB at 100MHz, providing effective suppression for high-frequency electromagnetic interference in compact electronic designs.

Feature Summary

• Dual-channel LC network configuration for simultaneous signal conditioning
• Surface mount design enabling automated assembly processes
• High-frequency attenuation characteristics for EMI suppression

Applications

• Signal line filtering in communication equipment
• Electromagnetic interference reduction in data processing units
• Noise suppression in sensitive analog circuitry

Procurement Notes

Verify the specific package dimensions and pinout configuration against the official datasheet before integration. Confirm that the 2.2 A current rating and 56.6 VAC voltage limit align with the target circuit requirements. Ensure compliance with RoHS directives if required by the end product specifications. Cross-reference the manufacturer part number to avoid confusion with similar LC networks.

Selection Notes

Select this component when dual-channel filtering is required in a compact form factor. The 2µH/82pF values are suitable for higher frequency applications where minimal impedance insertion is needed. Consider the SMD mounting style for space-constrained PCB layouts. Evaluate the 20dB attenuation at 100MHz against specific noise spectrum requirements to ensure adequate suppression without affecting desired signal integrity.
