CM0805C221R-10

Overview

The CM0805C221R-10 is a two-line common mode choke manufactured by Laird-Signal Integrity Products. It features an impedance of 220 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 300 mA. The component has a maximum DC resistance of 400 mOhms. It utilizes a surface mount installation style within a 0805 (2012 metric) package, measuring 2 mm in length, 1.2 mm in width, and 1.2 mm in height. The device operates reliably within a temperature range of -40°C to +125°C.

Feature Summary

Provides common mode noise suppression for dual signal lines
Designed for surface mount integration on printed circuit boards
Constructed as an unshielded component for standard EMI filtering applications

Applications

Signal line EMI filtering
Common mode noise suppression in electronic circuits
High-frequency interference reduction in compact devices

Procurement Notes

Verify the manufacturer designation against official Laird-Signal Integrity Products documentation to ensure authenticity. Confirm that the specific part number matches the required electrical parameters, including the 220 Ohm impedance and 300 mA current rating. Check RoHS compliance status through the provided datasheet links. Ensure the packaging format aligns with assembly requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring common mode noise attenuation for two signal lines. The 0805 footprint suits space-constrained layouts. Verify that the 300 mA current rating meets the operational load without saturation. Ensure the operating temperature range covers the intended environmental conditions. Compare the 400 mOhm DC resistance against power loss constraints in the target application design.

Part Context

This component belongs to the CM series of common mode chokes from Laird-Signal Integrity Products. It is categorized under inductors, chokes, and coils within the broader filter component family. The product serves as a passive electromagnetic interference suppression element, distinct from ferrite beads which typically handle single-line differential mode filtering.
