LLQBA321818T151K

Fixed Inductors Overview

The LLQBA321818T151K is a fixed wire-wound ferrite inductor manufactured by Taiyo Yuden. It features a 150 µH nominal inductance with a ±10% tolerance. The component has a maximum DC current rating of 105 mA and a maximum DC resistance of 4.16 Ohms. It operates within a temperature range of -40°C to +105°C and utilizes a 1207 (3218 metric) surface-mount package.

Fixed Inductors Feature Summary

• Semi-shielded wire-wound construction for reduced electromagnetic interference
• Ferrite core design optimized for power applications
• Surface-mount compatibility with standard PCB assembly processes

Fixed Inductors Applications

• Power supply filtering circuits
• DC-DC converter input/output stages
• General-purpose RF inductor applications

Fixed Inductors Procurement Notes

Verify the specific suffix 'LLQBA' against official Taiyo Yuden documentation, as standard series nomenclature typically uses 'LB'. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the supplier provides valid traceability documents matching the exact part number designation.

Fixed Inductors Selection Notes

Select this component when a 150 µH inductance value is required with a 105 mA current limit. The semi-shielded design aids in managing magnetic fields in dense layouts. Verify that the 4.16 Ohm DC resistance aligns with system efficiency requirements and thermal management capabilities.

Fixed Inductors Part Context

This part belongs to the broader category of fixed chip inductors from Taiyo Yuden. Similar variants in the LB series include different inductance values such as 15 µH or 100 µH. The LLQBA prefix may indicate a specific packaging or internal variant configuration distinct from the standard LB3218 series.

Fixed Inductors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source data. Cross-reference with other 1207 package 150 µH inductors only if electrical parameters match exactly.
