• High self-resonant frequency capability suitable for RF circuits
• Compact 01005 surface-mount footprint for dense PCB layouts

Fixed Inductors Applications

• RF filtering in wireless communication modules
• Impedance matching networks in mobile devices
• Signal conditioning in high-frequency circuitry

Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct shielding and tolerance specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity. Ensure storage conditions align with the component's humidity sensitivity classification.

Fixed Inductors Selection Notes

Select this component when a shielded inductor is required in a 01005 package for RF applications. The 18 nH value and 3.2 GHz self-resonant frequency make it suitable for higher frequency bands. Consider the 140 mA current rating and 2.8 Ohm DCR for power handling constraints. Compare against unshielded alternatives if EMI suppression is not a primary design constraint.

Fixed Inductors Part Context

This part belongs to TDK's MLG-Q series of multilayer chip inductors, which are engineered for high-frequency performance. The series offers various inductance values in small form factors, catering to the miniaturization trends in consumer electronics and telecommunications. The MLG-Q designation typically indicates specific shielding or performance characteristics distinct from other MLG sub-series.

Fixed Inductors Replacement Considerations

Consult the official TDK replacement guide for direct equivalents. Verify that any substitute matches the 18 nH inductance, 01005 package dimensions, and shielding type. Ensure the alternative component meets the same electrical parameters, including Q factor and self-resonant frequency, for circuit compatibility.
