Overview
The AWCU00453226513TT2 is a surface-mount common mode choke from Pulse Electronics, designed for automotive applications. It features an inductance of 51 µH at 100 kHz and offers an impedance of 2.8 kOhms at 10 MHz. The component supports a maximum DC current of 200 mA with a maximum DC resistance of 1 Ohm. It operates within a temperature range of -50°C to +150°C and holds AEC-Q200 qualification. The physical dimensions are 4.5 mm x 3.2 mm x 2.6 mm.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- High-temperature operation up to 150°C
- Ferrite core construction for signal line filtering
Applications
- Automotive CAN bus systems
- 100 Base-T1 Ethernet interfaces
- Signal line noise suppression
Procurement Notes
Verify the specific suffix TT2 against official datasheets to confirm package type and reel specifications. Ensure compatibility with automated SMD placement equipment given the 4.5x3.2mm footprint. Confirm RoHS3 compliance status if required by local regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.
Selection Notes
Select this component when designing for automotive environments requiring high thermal stability and compact form factors. The 51 µH inductance is suitable for standard CAN bus frequencies. Consider the 200 mA current rating against circuit load requirements. The unshielded design may require layout considerations for EMI sensitivity compared to shielded alternatives.
Part Context
This part belongs to the AWCU series of common mode chokes manufactured by Pulse Electronics. The series is specifically engineered for automotive data communication lines. It shares the same 4.5x3.2mm footprint family with other variants offering different inductance values, allowing for standardized PCB footprints across multiple designs.
Replacement Considerations
AWCU00453226510XG0: Similar 51 µH inductance but differs in impedance (3.5 kOhms) and packaging suffix. Verify pinout and mechanical height compatibility before substitution.
