IFLN1812CZER582N

Common Mode Chokes Overview

The Vishay Dale IFLN1812CZER582N is a surface-mount common mode choke designed for high-impedance noise suppression. It features an inductance of 100 µH and a DC resistance maximum of 2 Ohms. The component provides an impedance of 5.8 kOhms at 100 MHz and supports a maximum DC current of 200 mA. Operating within a temperature range of -55°C to +150°C, it utilizes a ferrite core in an unshielded SMD-4 package measuring 4.5 mm x 3.2 mm x 2.8 mm.

Common Mode Chokes Feature Summary

• High impedance performance for effective common mode noise attenuation
• Robust thermal stability suitable for demanding operating environments
• Compact surface-mount footprint optimized for space-constrained PCB layouts

Common Mode Chokes Applications

• DC to DC power supply circuits
• Signal line filtering
• Electromagnetic interference suppression

Common Mode Chokes Procurement Notes

Verify the specific impedance value and tolerance against the official datasheet before integration. Confirm that the 200 mA current rating meets the circuit requirements. Ensure the unshielded design does not interfere with adjacent components or sensitive traces on the board layout.

Common Mode Chokes Selection Notes

Select this component when high impedance at 100 MHz is required for noise reduction. The 1812 package size offers a balance between performance and board space. Consider the unshielded nature if magnetic coupling with nearby inductors is a concern. Verify compatibility with standard reflow soldering profiles.

Common Mode Chokes Part Context

This part belongs to the IFLN-1812CZ series of common mode chokes from Vishay Dale. The series is characterized by ferrite core construction and surface-mount packaging.
