#A914BYW-6R8M=P3

Overview

The #A914BYW-6R8M=P3 is a shielded surface-mount power inductor from Murata Electronics, designed for high-current applications. It features a wirewound construction with a ferrite core, housed in a compact 2020 (5.2mm x 5.2mm) package with a maximum height of 2.0mm. The component provides an inductance of 6.8 µH with a tolerance of ±20%. It supports a maximum DC current of 1.17 A and has a maximum DC resistance of 105 mOhms. The saturation current is rated at 1.0 A. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Shielded design minimizes electromagnetic interference and reduces sensitivity to nearby magnetic fields.
• Wirewound ferrite core construction ensures stable performance under varying load conditions.
• Compact SMD footprint facilitates automated assembly and space-efficient circuit board layouts.

Applications

• Power line chokes in portable electronic devices
• DC-DC converter input/output filtering
• General-purpose power supply filtering

Procurement Notes

Verify the specific suffix =P3 for packaging details, as it indicates tape and reel or cut tape availability depending on distributor stock. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as environmental declarations may vary by production batch. Check lead times carefully, as this component type may be subject to allocation or limited supply situations due to manufacturing constraints. Ensure the ordering quantity matches the minimum packaging requirements specified by the supplier.

Selection Notes

Select this component when a low-profile, shielded inductor is required for high-current DC-DC conversion circuits. The 6.8 µH value and 1.17 A current rating suit applications needing moderate energy storage with minimal size. Compare saturation current against peak load requirements to prevent performance degradation. Consider the 105 mOhm DCR impact on overall efficiency. Evaluate thermal management needs given the small package size and potential power dissipation.

Part Context

This part belongs to the A914BYW series of power inductors from Murata Electronics. The series is characterized by its shielded structure and suitability for space-constrained designs. Similar parts in the series include #A914BYW-150M=P3 and #A914BYW-4R7M=P3, which share the same package dimensions but differ in inductance and current ratings. The series is widely used in consumer electronics and industrial power supplies.

Replacement Considerations

Direct substitutes within the same series include #A914BYW-4R7M=P3 and #A914BYW-150M=P3, though inductance values differ. Cross-brand replacements require matching inductance, current ratings, and package dimensions. Verify that any alternative component meets the same shielding and temperature specifications to ensure circuit compatibility.
