Overview
The Bourns SRF4532TA-601Y is a shielded automotive common mode choke designed for EMI suppression and noise filtering. It features a ferrite core in an 1812 (4.5x3.2x2.8mm) surface-mount package. Key electrical parameters include an impedance of 600 Ohms at 100 MHz, an inductance of 1.7 uH, and a maximum DC current rating of 2.5 A. The component operates within a temperature range of -55°C to +125°C and has a maximum DC resistance of 60 mOhms.
Feature Summary
- Shielded construction minimizes magnetic field interference
- Automotive-grade reliability compliant with AEC-Q200 standards
- Compact surface-mount footprint suitable for high-density PCB layouts
Applications
- EMI suppression in automotive electronic systems
- Noise filtering for data lines and power circuits
- Signal integrity protection in vehicle infotainment units
Procurement Notes
Verify the specific suffix 'Y' corresponds to the required tape-and-reel packaging configuration. Confirm that the 600 Ohm impedance value aligns with the target frequency requirements for the intended EMI suppression application. Ensure the 2.5A current rating meets the circuit's peak load demands without saturation.
Selection Notes
Select this component when a compact, shielded common mode choke is required for automotive environments. The 1812 package size offers a balance between performance and board space. Consider the 600 Ohm impedance characteristic for effective high-frequency noise attenuation. Verify thermal stability requirements against the specified operating temperature range.
Part Context
This part belongs to the SRF4532TA series of common mode chip inductors from Bourns. The series is engineered for automotive applications requiring robust EMI performance. The 4532 metric dimensions define the standard footprint for this family of shielded components.
Replacement Considerations
Cross-reference with other SRF4532TA variants such as SRF4532TA-901Y for different impedance needs. Ensure substitute parts maintain the same 1812 package dimensions and AEC-Q200 automotive qualification status.
