Overview
The Bourns SRF4530A-510Y is a surface-mount common mode choke from the SRF4530A series, designed for high impedance filtering. It features an inductance of 51 µH at 100 kHz and a DC current rating of 230 mA. The component exhibits a maximum DC resistance (DCR) of 1 Ohm and provides an impedance of 3.5 kOhms at 10 MHz. Constructed with a ferrite drum core, it measures 4.5 mm in length, 3.2 mm in width, and 3 mm in height.
Feature Summary
- Bifilar wound construction on a ferrite drum core for effective noise suppression
- High impedance performance across a broad frequency range
- Automotive grade reliability compliant with AEC-Q200 standards
Applications
- Automotive electronic circuit protection
- Common mode noise filtering in data lines
- Signal integrity enhancement in compact modules
Procurement Notes
Verify the specific suffix '510Y' to confirm the 51 µH inductance value, as the SRF4530A series includes variants with different ratings. Ensure the procurement documentation explicitly states AEC-Q200 compliance if automotive qualification is required. Cross-reference the physical dimensions against the footprint requirements to guarantee compatibility with the intended PCB layout.
Selection Notes
Select this component when a low-profile, high-impedance filter is needed for sensitive signal lines. The 230 mA current rating suits low-power applications. Consider the bifilar winding structure for superior common mode rejection compared to standard chokes. Verify that the 1 Ohm DCR meets the voltage drop constraints of the target circuit design.
Part Context
This part belongs to the Bourns SRF4530A series of common mode chip inductors. These components are engineered for surface mount technology and are characterized by their small form factor and robust magnetic properties. The series is widely utilized in environments requiring reliable electromagnetic interference suppression.
Replacement Considerations
Direct substitutes include other SRF4530A series parts such as SRF4530A-101Y or SRF4530A-220Y, provided the inductance and current ratings align with the circuit requirements. Verify pinout and dimensional compatibility before substitution.
