Overview
The Bourns SRF2012-501YA is a two-channel common mode choke designed for surface mount technology. It features a ferrite core and operates within a temperature range of -40°C to +125°C. The component provides an impedance of 500 Ohms at 100 MHz with a tolerance of 35%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 500 mOhms. The physical dimensions are 2.0 mm x 1.2 mm x 1.45 mm, housed in a shielded package compliant with AEC-Q200 standards.
Feature Summary
- Provides effective EMI suppression for data and signal lines through common mode filtering.
- Constructed with a ferrite core and shielded design to minimize electromagnetic interference.
- Complies with AEC-Q200 automotive qualification standards for reliability.
Applications
- EMI suppression in automotive electronic systems
- Signal line filtering in data transmission circuits
- Common mode noise reduction in compact electronic devices
Procurement Notes
Verify the specific suffix 'A' in the part number SRF2012-501YA to confirm AEC-Q200 automotive compliance and exact impedance tolerance. Ensure the ordering documentation matches the required package type, such as Tape & Reel, and confirms the active product status before finalizing procurement.
Selection Notes
Select this component when space-constrained designs require a shielded common mode choke with AEC-Q200 certification. The low profile and small footprint suit high-density PCB layouts. Verify that the 300 mA current rating meets the circuit's operational requirements and that the 500 Ohm impedance aligns with the target noise frequency spectrum.
Part Context
This component belongs to the Bourns SRF2012 Series of common mode chip inductors. The series offers various impedance values tailored for different filtering needs. The SRF2012-501YA specifically targets applications requiring robust noise suppression in automotive and industrial environments while maintaining a compact form factor.
Replacement Considerations
Consider the SRF2012A-501YA as a confirmed substitute variant within the same series. Both parts share identical electrical characteristics and form factors. Verify compatibility with existing PCB footprints and ensure the replacement maintains the required AEC-Q200 qualification status.
