Voltage-Variable Capacitance (Tuning) Diodes CODI's voltage variable capacitor (VVC) product line is one of the broadest, high - quality lines in the industry. CODI offers VVCs with low leakage, ultra - high Q, high reverse voltage, very high capacitance, high capacitance to - voltage change ratio, and precise reproducible tracking of capacitance to voltage change. These characteristics make the CODI line of VVCs ideal for tuning, modulation and LINE HIGHLIGHTS High Q * High Voltage * Low Leakage JAN-JAN-TX QUALIFIED * High QO * High Voltage harmonic generation, especially when matched characteristics are required to assure CAP Qa Device CAP fe} Device tracking, or when matched and graded sets are required as in voltage variable delay lines.
