Overview
The Bourns SRF3225TAC-110Y is a surface-mount common mode choke filter designed for automotive applications. It features an 11 µH inductance at 100 kHz and provides 550 Ohms impedance at 10 MHz. The component supports a maximum DC current of 300 mA with a DCR of 400 mOhms. It operates within a temperature range of -40°C to +125°C. The unit utilizes a ferrite core, measures 3.2 mm x 2.5 mm x 2.5 mm, and complies with AEC-Q200 standards.
Feature Summary
- AEC-Q200 qualified for automotive reliability requirements
- Shielded ferrite core construction for effective noise suppression
- Compact surface-mount footprint suitable for space-constrained PCB layouts
Applications
- Automotive electronic circuit protection
- Signal line filtering in vehicle infotainment systems
- Data bus interference suppression in automotive networks
Procurement Notes
Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm packaging configuration and compliance status. Ensure the selected variant matches the required AEC-Q200 qualification level for your target application. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring common mode noise reduction in automotive environments. The 300 mA current rating and low DCR make it suitable for sensitive signal lines rather than high-power paths. Verify that the 11 µH inductance value aligns with the specific frequency attenuation requirements of the target data bus or signal interface.
Part Context
This component belongs to the Bourns SRF3225TAC series of shielded common mode chokes. The series is engineered specifically for automotive electronics, offering robust performance under varying thermal conditions. The 3225 package size provides a balance between electrical performance and board space efficiency for modern vehicle electronic control units.
Replacement Considerations
Consult the official Bourns replacement guide for verified cross-references. Ensure any substitute maintains AEC-Q200 certification and identical physical dimensions for direct PCB compatibility.
