LWW0402GT12N

Fixed Inductors Overview

The LWW0402GT12N is a general-purpose RF inductor manufactured by Stackpole Electronics Inc. It features a ceramic core and wirewound construction within a 0402 (1005 metric) surface-mount package. The component provides an inductance of 12 nH with a tolerance of ±2%. It has a maximum DC resistance of 120 mΩ and a rated current of 640 mA. The unit operates within a temperature range of -40°C to 125°C.

Fixed Inductors Feature Summary

• Wirewound construction utilizing a ceramic core for stable performance
• Designed specifically for RF applications requiring high Q factors
• Unshielded design suitable for compact surface-mount layouts

Fixed Inductors Applications

• RF circuit impedance matching networks
• High-frequency signal filtering stages
• General purpose inductive components in consumer electronics

Fixed Inductors Procurement Notes

Verify the specific suffix 'G' indicates the ±2% tolerance variant, distinct from standard 'J' tolerance parts. Confirm the manufacturer datasheet for the exact self-resonant frequency and Q factor curves at target operating frequencies. Ensure the 0402 footprint matches the PCB land pattern dimensions precisely to avoid assembly defects.

Fixed Inductors Selection Notes

Select this component when precise low-nanohenry inductance is required for RF tuning. The ±2% tolerance offers tighter control than standard ±5% parts. Consider the 640 mA current rating against peak circuit loads. The unshielded nature requires layout consideration to minimize electromagnetic interference with adjacent traces.

Fixed Inductors Part Context

This part belongs to the LWW series of fixed inductors from Stackpole Electronics. The series includes various packages and values tailored for different power and frequency requirements. The 0402 form factor allows for high-density mounting on printed circuit boards used in modern portable devices.

Fixed Inductors Replacement Considerations

LWW0402JT12N: Offers similar electrical characteristics but with ±5% tolerance instead of ±2%. Verify if the looser tolerance meets the design requirements for the specific application.
