Overview
The SRF4530A-510YH is a two-line common mode choke manufactured by Bourns Inc., designed for signal line filtering in electronic circuits. It features an inductance of 51 µH and a rated current of 230 mA. The component exhibits a common mode impedance of 3.5 kOhm at 10 MHz. It is housed in a horizontal surface mount package with four PC pads, measuring 4.5 mm in length, 3.2 mm in width, and 3 mm in height. The device operates within a temperature range of -55°C to +150°C, including temperature rise.
Feature Summary
- Provides effective common mode noise suppression for signal lines
- Qualified for automotive applications under AEC-Q200 standards
- Constructed with halogen-free materials for environmental compliance
Applications
- Automotive signal line filtering
- Electronic circuit noise suppression
- Common mode interference reduction in compact modules
Procurement Notes
Verify the specific suffix 'H' against official Bourns documentation to confirm exact mechanical and material specifications. Ensure compatibility with AEC-Q200 requirements if used in automotive contexts. Confirm RoHS3 compliance status through the manufacturer's latest datasheet before integration into production designs.
Selection Notes
Select this component when high common mode impedance is required at 10 MHz for low-current signal lines. The 230 mA rating suits sensitive data interfaces rather than power delivery. The horizontal footprint allows for space-constrained layouts where vertical chokes are unsuitable.
Part Context
This part belongs to the Bourns SRF series of shielded inductors and common mode chokes. The series is characterized by its compact surface mount design and suitability for high-frequency noise attenuation. The SRF4530A variant specifically targets automotive and industrial applications requiring robust EMI performance.
Replacement Considerations
Cross-reference with other Bourns SRF4530A variants or equivalent automotive-grade common mode chokes from other manufacturers. Verify that substitute parts match the 51 µH inductance, 230 mA current rating, and 3.5 kOhm impedance at 10 MHz.
