Overview
The Bourns SRF3225TAC-510Y is a surface-mount common mode choke designed for automotive applications. It features a ferrite core and bifilar winding within a 3.2 mm x 2.5 mm x 2.5 mm package. The component provides an inductance of 51 µH at 100 kHz and achieves a common mode impedance of 2.6 kΩ at 10 MHz. It supports a maximum DC current of 200 mA with a maximum DC resistance of 700 mΩ. Rated for voltages up to 80 V, it operates reliably between -55°C and +150°C and complies with AEC-Q200 standards.
Feature Summary
- Automotive-grade reliability certified under AEC-Q200 standards
- Shielded construction utilizing a ferrite core and bifilar winding
- Compact surface-mount footprint suitable for space-constrained PCB layouts
Applications
- Automotive electronic circuit protection
- Common mode noise suppression in data lines
- Signal integrity enhancement in vehicle communication systems
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm electrical characteristics and compliance status. Ensure the ordering code matches the required inductance and current ratings for the target application. Cross-reference datasheets from authorized distributors to validate package dimensions and terminal configurations before integration into production designs.
Selection Notes
Select this component when designing circuits requiring robust noise filtering in automotive environments. The 200 mA current rating and low DC resistance make it suitable for sensitive signal lines rather than high-power paths. Confirm that the 80 V voltage rating exceeds the system's operational peaks. The wide temperature range ensures stability across diverse climatic conditions encountered in vehicle operations.
Part Context
This part belongs to the Bourns SRF3225TAC series of automotive-grade common mode chokes. The series is engineered for high-performance noise suppression in compact form factors. These components are specifically optimized for protecting electronic modules in modern vehicles against electromagnetic interference while maintaining signal fidelity.
Replacement Considerations
Consult official substitution lists for verified equivalents. Generic replacements may not match the AEC-Q200 certification or precise impedance curves required for automotive safety systems.
