Application and Installation Notes
Ceramic resonators serve as cost-effective timing components in radio frequency equipment where the extreme precision of quartz crystals is not required. This 450kHz resonator is typically used in intermediate frequency stages, clock generation circuits, or signal processing sections of Icom transceivers. The integrated capacitor design provides a complete oscillator solution in a single compact package, with the three-terminal configuration including ground, input, and output connections. Ceramic resonators offer advantages including faster startup time, greater shock resistance, and lower cost compared to crystal oscillators while still providing adequate frequency stability for many radio applications.
Professional installation by a qualified radio technician is essential for this component. Surface mount resonator replacement requires precision soldering equipment including a temperature-controlled soldering station with appropriate tip size, quality flux, and proper desoldering tools. The four-pad mounting configuration requires careful alignment to ensure all terminals make proper electrical and mechanical contact with the PCB. Excessive heat during soldering can damage the ceramic element or alter its resonant characteristics, so quick, controlled soldering technique is critical. After installation, proper circuit operation should be verified using oscilloscope or frequency counter to confirm oscillation at the correct frequency.
This component should be replaced when troubleshooting timing-related issues, audio processing problems, or receiver sensitivity degradation that may be traced to intermediate frequency circuits. Symptoms of resonator failure can include loss of audio, distorted reception, frequency instability, or complete loss of receiver function. Always use genuine Icom replacement parts to maintain factory specifications and ensure reliable operation. This resonator replaces earlier part number 6070000210, providing updated specifications or improved reliability.
Ideal for authorized Icom service centers, professional radio repair technicians, and communications equipment maintenance facilities servicing commercial, public safety, and aviation radio systems.
