CM3822R151R-00

Overview

The CM3822R151R-00 is a discontinued surface mount common mode choke manufactured by Laird-Signal Integrity Products. It features six independent lines designed for power line filtering applications. The component provides an impedance of 150 Ohms at a test frequency of 100 MHz and supports a maximum DC current rating of 5 Amperes. Its direct current resistance (DCR) is specified at 20 milliohms. The device utilizes a vertical package with flat leads, suitable for automated surface mount assembly processes.

Feature Summary

• Six-line configuration for multi-phase or multi-circuit noise suppression
• High current handling capability for power line applications
• Surface mount design for compact PCB integration

Applications

• Power line EMI filtering in electronic equipment
• Multi-channel signal integrity protection
• Common mode noise suppression in industrial systems

Procurement Notes

This specific part number is officially obsolete and no longer manufactured. Verification of availability should focus on the designated replacement model, CM3822R151R-10, which serves as the direct substitute. Ensure that procurement sources explicitly confirm the active status of the replacement variant rather than the discontinued original code to avoid fulfillment errors.

Selection Notes

Designers requiring this electrical specification must select the active successor model, CM3822R151R-10. The replacement maintains identical functional parameters including the six-line architecture, 150 Ohm impedance, and 5A current rating. Verify that the updated suffix corresponds to current manufacturing standards and compliance requirements before finalizing the bill of materials.

Part Context

This component belongs to the Laird CM series of common mode chokes, engineered for high-current power line filtering. The six-line topology distinguishes it from standard single or dual-line variants, offering integrated noise suppression for complex power distribution networks within a single surface mount footprint.

Replacement Considerations

The official direct replacement is CM3822R151R-10. This substitute retains the same electrical characteristics and physical form factor, ensuring compatibility with existing footprints and circuit designs without requiring schematic modifications.
