Overview
The Bourns SRF4530AG-201Y is a two-line surface mount common mode choke designed for automotive applications. It features an inductance of 200 µH with a tolerance of -30% to +50%. The component has a maximum DC resistance of 4.5 mΩ and a rated DC current of 100 mA. It operates within a temperature range of -55°C to +150°C and holds AEC-Q200 qualification. The physical dimensions are 4.50 mm x 3.20 mm x 3.00 mm.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- High operating temperature capability up to 150°C
- Low DC resistance design for minimal power loss
- Compact surface mount footprint
Applications
- Automotive electronic circuit protection
- Common mode noise suppression in vehicle systems
- Signal line filtering in harsh thermal environments
Procurement Notes
Verify the specific suffix 'Y' corresponds to the required tape and reel packaging configuration. Confirm that the 100 mA current rating meets the application's continuous load requirements. Ensure the -55°C to +150°C temperature range aligns with the intended operational environment. Cross-reference the AEC-Q200 certification status if strict automotive compliance is mandated by the system design specifications.
Selection Notes
Select this component when a compact, high-temperature common mode choke is required for automotive use. The 200 µH inductance provides effective noise filtering for low-current signal lines. The low DCR minimizes voltage drop across the filter. Consider the 50V rating for compatibility with standard automotive logic and sensor voltages.
Part Context
This part belongs to the Bourns SRF4530AG series of common mode chokes. The series is characterized by its small 1812-like footprint and robust construction suitable for automated assembly. The AG designation typically indicates automotive-grade qualification and enhanced thermal performance compared to standard industrial variants.
Replacement Considerations
Direct substitutes must match the 200 µH inductance, 100 mA current rating, and 4.5x3.2x3.0 mm package. Verify equivalent AEC-Q200 certification and -55°C to +150°C temperature range. Check for compatible DC resistance values to ensure similar insertion loss characteristics.
