Overview
The Bourns SRF4530A-101Y is a surface-mount common mode choke designed for signal line protection. It features an inductance of 100 µH at 100 kHz and offers high impedance of 7.5 kOhms at 10 MHz. The component supports a maximum DC current of 200 mA with a maximum DC resistance of 1.5 Ohms. Rated for automotive applications under AEC-Q200 standards, it operates within a temperature range of -55°C to +150°C and utilizes a ferrite core construction.
Feature Summary
- Bifilar wound construction on a ferrite drum core for high impedance over broad frequency ranges
- Automotive-grade reliability certified to AEC-Q200 standards
- Wide operating temperature range suitable for harsh environments
Applications
- Signal line filtering in automotive electronics
- Common mode noise suppression in data communication interfaces
- Protection of sensitive circuits against electromagnetic interference
Procurement Notes
Verify the specific suffix 'A' indicates automotive qualification and AEC-Q200 compliance. Confirm package dimensions match the 1812 footprint requirements. Ensure the 200 mA current rating aligns with circuit design limits. Check RoHS status for environmental compliance. Validate supplier authenticity through authorized distribution channels.
Selection Notes
Select this component when high impedance at 10 MHz is required for signal integrity. The 1.5 Ohm DCR minimizes voltage drop in low-current signal paths. The wide temperature range ensures stability in automotive under-hood applications. Compare with SRF4532 series if larger packages are permissible for thermal management.
Part Context
This part belongs to the Bourns SRF4530A series of common mode chokes. The series includes variants with different inductance values such as 51 µH and 11 µH. All parts share similar bifilar winding technology and ferrite core materials. The series targets compact designs requiring effective noise suppression in limited space.
Replacement Considerations
Direct substitutes include other SRF4530A series variants like SRF4530A-510Y or SRF4530A-110Y if inductance differences are acceptable. Cross-series replacement with SRF4532 models requires verification of package size compatibility.
