AWCU00453226223TM2

Overview

The AWCU00453226223TM2 is a single-channel common mode choke manufactured by Pulse Electronics, designed for automotive applications. It features a ferrite core and surface-mount (SMD/SMT) termination style within the AWCU series. Key electrical parameters include an inductance of 22 µH measured at a test frequency of 100 kHz, a maximum DC current rating of 310 mA, and a maximum DC resistance of 600 mOhms. The component operates within a temperature range of -55°C to +150°C and holds AEC-Q200 qualification. Its physical dimensions are 4.5 mm x 3.2 mm x 2.8 mm.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Ferrite core construction for effective noise suppression
• Compact surface-mount design suitable for space-constrained PCBs

Applications

• Automotive CAN bus systems
• Common mode noise filtering in vehicle electronics
• Signal line protection in automotive control units

Procurement Notes

Verify the specific suffix TM2 against official Pulse Electronics documentation to confirm packaging configuration and compliance status. Ensure the procurement channel sources genuine components with traceable manufacturing data. Cross-reference the AEC-Q200 certification details directly with the manufacturer's latest datasheet to validate automotive grade specifications before integration into production designs.

Selection Notes

Select this component when designing automotive circuits requiring robust common mode noise attenuation with high thermal stability. The 310 mA current rating and low DCR make it suitable for sensitive signal lines where power loss must be minimized. Verify that the 4.5x3.2mm footprint aligns with the target PCB layout constraints and that the operating temperature range meets the specific environmental requirements of the installation site.

Part Context

This part belongs to the AWCU series of common mode chokes from Pulse Electronics, specifically engineered for the automotive sector. The series emphasizes compact form factors and high reliability under harsh conditions. As an AEC-Q200 certified component, it adheres to strict quality and performance standards required for critical vehicle electronic systems, distinguishing it from general-purpose industrial filters.

Replacement Considerations

Consult official Pulse Electronics substitution guides or equivalent automotive-grade common mode chokes with matching inductance, current ratings, and footprint dimensions. Verify compatibility with existing PCB footprints and ensure any substitute maintains AEC-Q200 certification if automotive reliability is required.
