Fixed Inductors Procurement Notes

Verify RoHS compliance status as historical data indicates non-compliance; confirm current manufacturing specifications directly with API Delevan. Check for specific ordering suffixes that may alter electrical parameters or packaging. Ensure the required tolerance and current ratings align with the target application constraints before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a precise 5.6 µH inductance is required with minimal deviation. The unshielded design necessitates careful layout to prevent magnetic coupling with nearby components. Verify that the 195 mA current rating meets the peak load requirements of the circuit to avoid saturation or overheating issues during operation.

Fixed Inductors Part Context

This part belongs to the 1025 series of fixed inductors manufactured by API Delevan. These components are characterized by their molded construction and axial leads, designed for through-hole applications. The series is known for providing consistent performance in radio frequency environments where stability and reliability are critical factors.

Fixed Inductors Replacement Considerations

The 2510-38F is a surface mount variant with different physical dimensions and electrical characteristics (3.9 µH). Direct substitution requires verifying footprint compatibility and ensuring the inductance value matches the circuit design requirements.
