Overview
The Bourns SRF0602-820Y is a surface-mount common mode filter choke designed for signal line applications. It features an inductance of 82 µH with a tolerance of ±50% and a maximum DC current rating of 300 mA. The component exhibits a minimum impedance of 220 Ohms within the 3 MHz to 850 MHz frequency range and a maximum DC resistance of 20 mOhms. Housed in a compact 0602 package measuring 6.5 mm x 3.6 mm x 1.65 mm, it operates reliably between -40°C and +105°C.
Feature Summary
- Suppresses electromagnetic interference (EMI) and radio frequency interference (RFI) noise on signal lines
- Utilizes ferrite core material for effective high-frequency filtering performance
- Designed for surface mount technology (SMD/SMT) PCB integration
Applications
- Signal line filtering in electronic circuits
- EMI/RFI suppression in data transmission interfaces
- Noise reduction in compact consumer electronics
Procurement Notes
Verify the specific ordering suffix against official Bourns documentation to ensure correct electrical characteristics. Confirm that the requested quantity aligns with standard factory packaging configurations. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when space-constrained designs require a common mode choke with 82 µH inductance and 300 mA current handling. Ensure the operating environment remains within the specified -40°C to +105°C temperature range. Verify that the 0602 footprint matches the target PCB layout constraints and that the impedance profile meets the required noise suppression specifications for the application frequency.
Part Context
This component belongs to the Bourns SRF0602 series of common mode chokes. The series offers various inductance values in a standardized miniature footprint, allowing designers to scale filtering requirements while maintaining consistent mechanical dimensions and mounting profiles across different product variants within the same family.
Replacement Considerations
Consult official Bourns substitution guides for verified alternatives. Ensure any replacement maintains identical inductance, current ratings, and physical dimensions to preserve circuit integrity and PCB compatibility.
