SRF4532TA-901Y

Overview

The Bourns SRF4532TA-901Y is a shielded common mode choke designed for surface mount applications. It features an inductance of 3.2 uH and provides an impedance of 900 Ohms at 100 MHz. The component supports a maximum DC current of 2.3 A with a maximum DC resistance of 70 mOhms. Housed in a compact 1812 (4.5x3.2x2.8 mm) package, it operates within a temperature range of -55 C to +125 C. This ferrite core device is rated for 50 VDC and meets automotive reliability standards.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• High current handling capability suitable for power line filtering
• Automotive-grade reliability certification ensures durability in harsh environments

Applications

• EMI suppression in automotive electronic systems
• Noise filtering for high-speed data lines
• Common mode noise reduction in power supply circuits

Procurement Notes

Verify the specific suffix Y against the manufacturer's latest datasheet to confirm impedance tolerance and packaging configuration. Ensure the ordering part number matches the required AEC-Q200 qualification status if automotive compliance is mandatory. Cross-reference the impedance value at 100 MHz with circuit simulation requirements before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a 1812 footprint with high current capacity. The 900 Ohm impedance at 100 MHz targets specific frequency bands for noise attenuation. Evaluate the 2.3 A saturation current against peak load conditions to prevent performance degradation. Consider the shielded design for sensitive layouts where magnetic field leakage must be contained.

Part Context

This part belongs to the SRF4532TA series of common mode chip inductors from Bourns. The series offers various impedance values ranging from 90 Ohms to 2800 Ohms at 100 MHz. These components are engineered for EMI suppression in compact electronic designs requiring robust shielding and high current ratings.

Replacement Considerations

Consult the official Bourns SRF4532TA series datasheet for direct substitutes with identical impedance and current ratings. Verify pin compatibility and thermal characteristics before integrating alternative components into existing PCB layouts.
