Overview
The AWCU00201212121M02 is a surface-mount common mode choke from Pulse Electronics, designed for automotive CAN bus systems. It features an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 20%. The component supports a maximum DC current of 400 mA and has a maximum DC resistance of 300 mOhms. It operates within a temperature range of -50°C to +150°C. The physical dimensions are 2.05 mm in length, 1.25 mm in width, and 1.2 mm in height, utilizing SMD/SMT termination on a PCB mount.
Feature Summary
- Designed specifically for automotive CAN bus system applications
- Utilizes ferrite core material for effective noise suppression
- Unshielded construction suitable for standard signal line filtering
Applications
- Automotive CAN bus systems
- Signal line filtering
- Common mode noise suppression in vehicle electronics
Procurement Notes
Verify the specific manufacturing date code and RoHS compliance status directly with the supplier or manufacturer before procurement. Confirm that the AEC-Q200 qualification requirements align with your specific automotive application standards. Ensure the storage conditions maintain the integrity of the ferrite core and solderability of the SMD terminals during handling.
Selection Notes
Select this component when space-constrained automotive designs require a compact footprint of 2.05 x 1.25 mm. The 120 Ohm impedance rating is appropriate for high-frequency noise attenuation in CAN bus networks. Consider the 400 mA current rating to ensure it meets the operational load without saturation. Verify compatibility with automated pick-and-place equipment due to the small SMD package size.
Part Context
This part belongs to the AWCU series of common mode chokes manufactured by Pulse Electronics. The series is characterized by its suitability for harsh automotive environments, offering wide operating temperature ranges. It serves as a specialized passive component for protecting sensitive communication lines against electromagnetic interference in modern vehicle architectures.
Replacement Considerations
Check for direct substitutes within the AWCU series with identical impedance and current ratings. Verify mechanical compatibility with existing PCB footprints if considering alternative manufacturers. Ensure any replacement maintains the same thermal performance and automotive qualification standards.
