AWCU00201212671M02

Overview

The AWCU00201212671M02 is a surface-mount common mode choke manufactured by Pulse Electronics. It features a ferrite core and an unshielded design suitable for automotive applications. The component has a 140 mA maximum DC current rating and a maximum DC resistance of 600 mOhms. Impedance is specified at 670 Ohms with a tolerance of 20%. Physical dimensions are 2.0 mm x 1.2 mm x 1.2 mm. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Designed for signal line filtering in automotive environments
• Utilizes a compact horizontal surface mount package
• Constructed with a ferrite core material

Applications

• Automotive CAN Bus systems
• Signal line protection
• Common mode noise suppression

Procurement Notes

Verify the specific impedance value against official datasheets, as conflicting public records list either 120 Ohms or 670 Ohms. Confirm AEC-Q200 qualification status directly with the manufacturer. Ensure the selected variant matches the required DC current rating of 140 mA for the target circuit design.

Selection Notes

Select this component for space-constrained automotive PCB layouts requiring low-profile filtering. The 0805 footprint allows for dense assembly. Verify thermal performance at the maximum operating temperature of 150°C. Ensure the unshielded nature does not interfere with nearby sensitive components.

Part Context

This part belongs to the AWCU series of automotive-grade common mode chokes from Pulse Electronics. These components are engineered specifically for high-reliability automotive data bus applications. The series emphasizes small form factors to accommodate modern vehicle electronics packaging requirements.
