ICM1812ER201V

Common Mode Chokes Overview

The ICM1812ER201V is a common mode choke manufactured by Vishay / Dale, designed for surface mount technology (SMD) applications. It features a ferrite core and operates within a temperature range of -40°C to +125°C. The component has an impedance of 200 Ohms with a tolerance of 25% at a test frequency of 100 MHz. It supports a maximum DC current of 200 mA and exhibits a maximum DC resistance of 50 mOhms. The physical dimensions are 4.5 mm in length, 3.2 mm in width, and 2.8 mm in height, conforming to the 1812 package style.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for differential signal lines
• Utilizes a ferrite core material for effective high-frequency filtering
• Designed for direct PCB mounting via standard SMD terminations

Common Mode Chokes Applications

• DC/DC power supply circuits
• Data line protection
• RF interference suppression

Common Mode Chokes Procurement Notes

Verify the specific impedance value and tolerance against the official Vishay datasheet before procurement. Confirm that the operating temperature range and current ratings align with the target circuit requirements. Ensure compatibility with the 1812 footprint during layout verification.

Common Mode Chokes Selection Notes

Select this component when a 200 Ohm impedance at 100 MHz is required for common mode noise reduction. Consider the 200 mA current rating and low DC resistance to minimize voltage drop. The 1812 package size offers a balance between performance and board space efficiency for dense layouts.

Common Mode Chokes Part Context

This part belongs to the ICM1812 series of common mode chokes from Vishay / Dale. The series provides various impedance options within the same 1812 footprint, allowing designers to select appropriate filtering characteristics without changing the mechanical design of the printed circuit board.

Common Mode Chokes Replacement Considerations

Check for other parts in the ICM1812 series with similar impedance values. Verify pinout and dimensional compatibility before substituting with components from other manufacturers.
