It features a compact 1616 (4040 metric) surface-mount package designed for high-current applications. The component provides an inductance of 0.5 µH with a tolerance of ±20%. It supports a saturation current of 3.15 A and has a DC resistance of 30 mΩ. The device operates reliably within a temperature range of -55°C to +125°C.

Fixed Inductors Feature Summary

• Shielded wirewound construction utilizing magnetic resin sealing
• Compact 1616 surface-mount footprint for space-constrained designs
• High current handling capability suitable for power supply circuits

Fixed Inductors Applications

• DC-DC converter output filtering
• Point-of-load regulation stages
• General-purpose power supply input/output chokes

Fixed Inductors Procurement Notes

Verify the specific suffix 'R50M' corresponds to the required 0.5 µH value and ±20% tolerance during procurement. Confirm that the 1616 package dimensions align with the target PCB layout. Ensure the operating environment remains within the specified -55°C to +125°C range to maintain performance integrity. Cross-reference the datasheet for precise thermal derating curves if ambient temperatures are elevated.

Fixed Inductors Selection Notes

Select this component when a low-profile, shielded inductor is required for high-current DC-DC conversion. The 3.15 A saturation current makes it suitable for loads demanding significant ripple current handling. The 30 mΩ DC resistance helps minimize conduction losses in efficient power architectures. Consider the 1616 package size against available board real estate and soldering capabilities.

Fixed Inductors Part Context

This part belongs to the CTLV4012ASF series of shielded power inductors from Central Technologies. The series offers various inductance values and current ratings within the same 1616 footprint. It is designed to replace older unshielded designs where electromagnetic interference suppression is critical. The magnetic resin encapsulation provides mechanical stability and environmental protection.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0.5 µH, 1616 package shielded inductors with comparable current ratings. Verify pin compatibility and thermal characteristics before substitution. Alternative parts must meet or exceed the 3.15 A saturation current and 30 mΩ DC resistance specifications.
