Procurement Notes
Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the 400 mA current rating and 50 VDC voltage limit align with your circuit requirements. Ensure the surface mount package dimensions match your PCB footprint design to avoid mechanical interference.
Selection Notes
Select this component when a 500 µH inductance value is required for common mode noise filtering. Consider the 400 mA current handling capability and low DC resistance for efficiency. Evaluate the surface mount form factor against available board space and assembly capabilities compared to through-hole alternatives.
Part Context
This part belongs to the Bourns SRF1306 series of EMI filter circuits. The series offers various inductance values ranging from 35 to 1000 μH, allowing designers to tailor noise suppression characteristics. These components are designed for general-purpose line filtering and EMI control in compact electronic devices.
Replacement Considerations
Other parts within the SRF1306 series may serve as substitutes if different inductance values are acceptable. Verify pinout compatibility and physical dimensions before replacing. Consult the manufacturer's selection guide for equivalent components with similar current and voltage ratings.
