Fixed Inductors Procurement Notes

Verify the specific suffix 'M' indicates the required ±20% tolerance during procurement. Confirm that the operating voltage does not exceed the manufacturer's rated limits. Ensure the footprint matches the 12.5 x 12.5 mm dimensions on the PCB layout. Request the official datasheet to validate thermal performance under expected load conditions before finalizing orders.

Fixed Inductors Selection Notes

Select this component when a high inductance value is required for effective ripple reduction in power conversion stages. The shielded construction makes it suitable for applications sensitive to magnetic coupling. Consider the 1.0 A RMS current rating against the circuit's continuous load requirements. Evaluate the physical size constraints to ensure compatibility with the available board space.

Fixed Inductors Part Context

This part belongs to the CTSLF1255TF series of shielded power inductors from Central Technologies. The series offers various inductance values tailored for different power management needs. These components are designed to replace older unshielded designs where EMI suppression was insufficient. The model number indicates specific electrical characteristics within the broader product family.

Fixed Inductors Replacement Considerations

Direct substitutes include other 680 µH shielded SMD inductors with comparable current ratings. Verify that alternative parts match the 12.5 x 12.5 mm footprint to avoid rework. Check if competitor components offer similar DCR values to maintain efficiency levels.
