10M331KLF

Overview

The 10M331KLF is an unshielded wirewound axial lead inductor manufactured by Gowanda Electronics. It features a nominal inductance of 3.3 µH with a tolerance of ±10%. The component has a maximum DC resistance of 850 mΩ and a minimum quality factor of 45 at a test frequency of 7.9 MHz. It supports a maximum rated current of 270 mA and operates within a temperature range of -55 °C to +125 °C.

Feature Summary

• Unshielded wirewound construction for minimal magnetic interference
• Axial lead configuration for through-hole mounting
• High Q factor stability at specified RF frequencies

Applications

• Commercial off-the-shelf (COTS) electronic circuits
• Broadband RF signal processing systems
• Aerospace and defense instrumentation

Procurement Notes

Verify the specific RoHS compliance status and lead finish details against the manufacturer's latest documentation before procurement. Confirm that the axial lead spacing matches the target PCB footprint requirements. Ensure the 270 mA current rating meets the thermal dissipation needs of the final assembly environment.

Selection Notes

Select this component when an unshielded axial inductor is required for RF applications to prevent magnetic coupling issues. The 3.3 µH value and 850 mΩ resistance are suitable for low-power signal filtering. Consider the 45 minimum Q factor for high-frequency performance requirements in aerospace or medical contexts.
