Procurement Notes

Verify the specific capacitance rank (S or T) required for your circuit design against the datasheet classification. Confirm that the 6.5V maximum reverse voltage rating aligns with your application's operating conditions. Ensure compatibility with the specified surface-mount footprint dimensions during PCB layout.

Selection Notes

Select the appropriate capacitance rank based on the target tuning range and Q-factor requirements. Verify that the operating voltage remains within the 6.5V limit to prevent damage. Consider the temperature stability characteristics shown in the capacitance ratio graphs when designing for varying ambient conditions.

Part Context

This component belongs to the SVC383 series of composite varactor diodes originally manufactured by SANYO Electric Co., Ltd. Semiconductor Company. These devices are engineered specifically for analog tuning applications where high Q and low voltage operation are critical. The product line emphasizes miniaturization for modern consumer electronics.

Replacement Considerations

Consult official distributors for current availability as this is a legacy SANYO product. Verify pinout compatibility and electrical specifications if considering alternative twin-varactor diodes from other manufacturers.
