PIM4R7M1004A3

Fixed Inductors Overview

The PIM4R7M1004A3 is a shielded molded power inductor from Meritek Electronics Corporation, designed for high-current applications. It features a fixed inductance of 4.7 µH with a maximum DC resistance (DCR) of 19 mΩ. The component utilizes a metal alloy powder core and a shielded structure to minimize electromagnetic interference. It supports a saturation current of 8.8 A and a RMS current rating of 6.5 A. The device is available in an 1004 metric surface-mount package, suitable for automated assembly processes.

Fixed Inductors Feature Summary

• Shielded molded construction reduces magnetic flux leakage and EMI
• High saturation current capability for stable performance under load
• Low DC resistance minimizes conduction losses
• Metal alloy powder core ensures thermal stability

Fixed Inductors Applications

• Point-of-load (POL) voltage regulation modules
• DC-DC converter input/output filtering
• High-density power supply designs
• Portable electronic device power management

Fixed Inductors Procurement Notes

Verify the specific suffix 'A3' against the manufacturer's latest datasheet to confirm packaging and tape-and-reel specifications. Ensure compatibility with reflow soldering profiles defined in the component's thermal characteristics. Confirm RoHS compliance status as per the most recent environmental declaration provided by Meritek Electronics Corporation.

Fixed Inductors Selection Notes

Select this component when low profile and high current density are required. The 1004 package size offers a compact footprint for space-constrained boards. Evaluate the 19 mΩ DCR against system efficiency targets. Consider the 8.8 A saturation limit relative to peak load currents to prevent inductance drop-off.

Fixed Inductors Part Context

This part belongs to the PIM series of molded power inductors from Meritek. The series is characterized by high current handling and low loss. The '4R7' designation indicates the nominal inductance value. The '1004' refers to the case size dimensions in millimeters. These components are engineered for modern switching power supplies requiring reliability and miniaturization.

Fixed Inductors Replacement Considerations

Cross-reference with other 4.7 µH, 1004 package inductors from different manufacturers if supply constraints exist. Verify that substitute parts meet or exceed the 19 mΩ DCR and 8.8 A saturation current requirements. Ensure physical dimensions and terminal configurations are compatible with existing PCB footprints.
