LWW0402JT40N

Fixed Inductors Overview

The LWW0402JT40N is a fixed surface-mount inductor manufactured by Stackpole Electronics Inc. It features an inductance of 40 nH with a tolerance of ±5%. The component utilizes a ceramic core and wire-wound construction, housed in a compact 0402 (1005 metric) package. It has a maximum DC resistance of 300 milliohms and a rated current of 400 mA. The self-resonant frequency is 2.48 GHz, with a Q factor of 24 measured at 250 MHz. Operating temperature range spans from -40°C to 125°C.

Fixed Inductors Feature Summary

• Wire-wound construction on a ceramic core for stable RF performance
• Unshielded design suitable for general RF applications
• Compact 0402 surface-mount footprint

Fixed Inductors Applications

• RF circuit impedance matching networks
• High-frequency signal filtering
• Inductive coupling components in RF modules

Fixed Inductors Procurement Notes

Verify the specific inductance value against the datasheet before procurement, as suffixes may indicate different values within the series. Confirm that the 400 mA rated current and 300 milliohm DCR meet the target circuit requirements. Ensure the unshielded nature does not cause interference in dense layouts. Check RoHS compliance status if required by project specifications.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-self-resonant-frequency solution is needed in a small form factor. The 40 nH value suits high-frequency applications where parasitic effects must be minimized. Consider the unshielded topology for cost-sensitive designs or where magnetic shielding is handled externally. Verify thermal management capabilities within the specified operating temperature range.
