Capacitance (pF) 120 Max. Capacitance (pF) 1400 Mounting Leaded CAPACITANCE RANGE 120 pF to 1.4 nF per single disc CERAMIC DIELECTRIC R4000 (Y5U) RATED VOLTAGE • 8.0 kVDC per single disc • 10 kVDC per single disc DESCRIPTION Voltage multipliers are AC/DC power conversion devices, comprised of diodes and capacitor stacks, that produce a high potential DC voltage from a lower voltage AC source. Multipliers consist of multiple stacks of up to 14 stages. Each stage is comprised of one diode and one capacitor. A high-frequency generator supplies the input AC voltage via a ferrite transformer. Output DC voltage up to 100 kV or higher can be produced, depending on the number of stages. The most common type of voltage multiplier is the half-wave multiplier, also called the Villard cascade. Another multiplier is the full-wave, also called the Delon circuit. Vishay has the product lines to offer customized voltage multiplier sets: • Build up to 14 stages or more • Circuits are completely assembled and soldered with HV diodes / resistors and screwed connections Please contact us. Our design team will work with you to find an individually solution.
