LSQBA201212T220K

Fixed Inductors Overview

The LSQBA201212T220K is a fixed wire-wound ferrite inductor from Taiyo Yuden, designed for surface-mount applications. It features a semi-shielded construction within an 0805 (2012 metric) package measuring 2.0 mm x 1.25 mm x 1.2 mm. The component provides an inductance of 22 µH with a tolerance of ±20%. It supports a maximum DC current of 80 mA and exhibits a DC resistance of 1.7 Ohms. The device operates reliably within a temperature range of -40°C to +105°C.

Fixed Inductors Feature Summary

• Semi-shielded wire-wound ferrite design reduces electromagnetic interference.
• Compact 0805 footprint suitable for space-constrained PCB layouts.
• Optimized for power supply circuit noise suppression.

Fixed Inductors Applications

• Power supply circuits for digital still cameras (DSC)
• Noise suppression in hard disk drives (HDD)
• Anti-noise measures for LCD televisions
• Mobile phone power management systems

Fixed Inductors Procurement Notes

Verify the specific suffix 'K' against the manufacturer's official datasheet to confirm packaging configuration and tape-and-reel specifications. Ensure the selected variant matches the required 22 µH inductance and 80 mA current rating for the target application. Cross-reference the RoHS compliance status and lead-free soldering compatibility prior to final procurement approval.

Fixed Inductors Selection Notes

Select this component when a compact, semi-shielded inductor is required for low-current power filtering. The 0805 size offers a balance between current handling and board area efficiency. Consider the 1.7 Ohm DC resistance impact on voltage drop and the 80 mA saturation limit. This part is appropriate for general consumer electronics where moderate shielding is sufficient to mitigate magnetic field leakage.

Fixed Inductors Part Context

This model belongs to the LSQB series of wire-wound ferrite inductors manufactured by Taiyo Yuden. The series is engineered specifically for anti-noise measures in portable electronic devices. The LSQB line utilizes a semi-shielded structure to minimize external magnetic fields while maintaining a small profile. These components are widely used in mobile phones, PCs, and game equipment for power line stabilization.

Fixed Inductors Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any alternative maintains the 22 µH value, 0805 dimensions, and similar current ratings. Ensure thermal characteristics and shielding requirements align with the original design constraints before substitution.
