Overview
The 15M222KLF is a fixed inductor manufactured by Gowanda Electronics, classified as an unshielded molded wirewound component with axial leads. It features a nominal inductance of 22 µH and a tolerance of 10%. The device has a maximum DC resistance of 2.5 Ohms and a rated DC current of 175 mA. Its self-resonant frequency is specified at 30 MHz, with a Q-factor of 75. The unit operates within a temperature range of -55 °C to +125 °C and complies with RoHS standards.
Feature Summary
- Unshielded molded wirewound construction for RF applications
- Axial lead configuration for through-hole mounting
- High Q-factor of 75 at nominal inductance
Applications
- RF coil circuits
- Filter networks
- Tuning applications
Procurement Notes
Verify the specific suffix 'LF' indicates lead-free compliance against the manufacturer's current datasheet. Confirm that the axial package style matches the target PCB layout requirements. Ensure the 175 mA current rating meets the circuit's operational demands without saturation.
Selection Notes
Select this component when an unshielded axial inductor is required for RF or general-purpose filtering. The 22 µH value and 30 MHz self-resonant frequency suit specific frequency ranges. Consider the 2.5 Ohm DC resistance impact on circuit efficiency during design.
Part Context
This part belongs to Gowanda Electronics' line of molded unshielded RF coils. It is distinct from surface mount variants like the SMRF series. The product is designed for precision electronic applications requiring stable inductance values in RF and microwave contexts.
Replacement Considerations
Cross-reference with other Gowanda axial inductors such as the 15M222K (non-LF) if lead-free status is not critical. Verify equivalent parameters from other manufacturers only if electrical characteristics match exactly.
FAQ
