ICM0603ER181V

Common Mode Chokes Overview

The Vishay Dale ICM0603ER181V is a single-channel common mode filter choke designed for surface mount technology. It features a ferrite core and operates within a temperature range of -40°C to +125°C. The component exhibits an impedance of 180 Ohms with a tolerance of 25% at a test frequency of 100 MHz. Its maximum DC resistance is specified at 80 mOhms. The device is housed in a compact 0603 (1608 metric) package, measuring 1.6 mm in length, 0.85 mm in width, and 1.25 mm in height.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for signal lines using a ferrite core structure.
• Designed for high-temperature reliability with an operational limit up to +125°C.
• Utilizes an unshielded configuration suitable for standard PCB mounting applications.

Common Mode Chokes Applications

• DC/DC Power Supplies
• Signal Line Filtering

Common Mode Chokes Procurement Notes

Verify the specific impedance value against the datasheet, as the model number suggests 180 Ohms while some listings may indicate variations. Confirm RoHS compliance status through official documentation. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, to align with assembly requirements. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Common Mode Chokes Selection Notes

Select this component when space constraints require a 0603 footprint for common mode filtering. Consider the 180 Ohm impedance rating for target noise frequencies around 100 MHz. Evaluate the 80 mOhms DC resistance to ensure minimal voltage drop in the circuit. Verify that the +125°C operating temperature meets the environmental conditions of the final application.

Common Mode Chokes Part Context

This component belongs to the Vishay Dale ICM0603 series of common mode chokes. It shares physical dimensions with other variants in the series but differs in impedance ratings. The series is characterized by its small form factor and suitability for dense PCB layouts. It serves as a passive electromagnetic interference suppression element in electronic circuits.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the ICM0603 series with matching 180 Ohm impedance. Verify package compatibility with existing footprints. Ensure thermal and electrical specifications meet or exceed original requirements before substitution.
