CTMMP73VCZF-4R7M

Fixed Inductors Overview

The CTMMP73VCZF-4R7M is a shielded surface-mount power inductor from Central Technologies, featuring a nominal inductance of 4.7 µH with a ±20% tolerance. It utilizes a metal mold construction and operates within a temperature range of -55°C to +125°C. The component has a maximum rated current of 9 A, which corresponds to an approximate temperature rise (ΔT) of 40°C. Its DC resistance is specified at 35 mΩ. Designed for general-purpose applications, it supports automated surface-mount assembly processes.

Fixed Inductors Feature Summary

• Metal mold construction provides robust shielding against electromagnetic interference.
• Surface-mount design facilitates efficient placement on printed circuit boards.
• High current handling capability suitable for demanding power supply circuits.

Fixed Inductors Applications

• Synchronous buck converter output filtering
• General-purpose power inductor applications

Fixed Inductors Procurement Notes

Verify the specific part number suffix to confirm RoHS compliance status, as manufacturing revisions may alter environmental certifications. Ensure that the required operating temperature range aligns with the component's specified limits of -55°C to +125°C. Confirm that the application current does not exceed the 9 A rating to prevent excessive thermal stress during operation.

Fixed Inductors Selection Notes

Select this component when a compact, shielded solution is required for high-current switching applications. The 4.7 µH value and 9 A rating make it appropriate for medium-power conversion stages. Consider the physical footprint compatibility with existing PCB layouts and verify that the 35 mΩ DC resistance meets the efficiency requirements of the target power supply design.

Fixed Inductors Part Context

This component belongs to the CTMMP73VCZF series of shielded power inductors manufactured by Central Technologies. The series offers various inductance values tailored for different power management needs. These components are designed to provide reliable performance in space-constrained electronic assemblies requiring effective magnetic shielding and stable electrical characteristics under load.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 4.7 µH inductance, 9 A current rating, and 35 mΩ DC resistance. Verify that any alternative component maintains the same surface-mount package dimensions and shielding type to ensure mechanical fit and electromagnetic compatibility without redesigning the surrounding circuitry.
