Application and Installation Notes
Wire-wound inductors are critical components in radio frequency circuits where precise inductance values and high quality factors are required. This 22nH inductor is typically used in RF matching networks that optimize power transfer between circuit stages, in filtering applications that suppress unwanted frequencies or harmonics, or in tuning circuits that set resonant frequencies. The low inductance value suggests application in VHF or UHF frequency ranges where even small inductance values have significant effect on circuit behavior. The ceramic core provides stable performance across the wide temperature ranges encountered in mobile and portable radio equipment.
Professional installation by an experienced RF technician is strongly recommended for this component. Surface mount inductor replacement requires specialized skills and equipment including a temperature-controlled soldering station, precision tweezers, proper flux, and ideally a hot air rework station for clean removal of the original component. The extended mounting tabs must make solid electrical and mechanical contact with the PCB pads. Take extreme care not to damage the delicate copper windings during handling or installation. After replacement, RF performance must be verified using appropriate test equipment such as network analyzers, power meters, or spectrum analyzers to ensure proper impedance matching and filtering characteristics.
This inductor should be replaced during troubleshooting of RF-related issues including poor transmit power output, high VSWR readings, spurious emissions, receiver desensitization, or impedance mismatch symptoms. Physical damage to the wire windings, broken solder connections, or thermal stress can cause inductance drift or complete component failure. Always use genuine Icom replacement parts as inductance tolerance, quality factor, and self-resonant frequency are critical parameters that must match original specifications for proper radio operation.
Ideal for authorized Icom service centers, professional RF technicians, and communications equipment repair facilities specializing in commercial two-way radio maintenance and alignment.
