0.33UF 1200V High Voltage Capacitor For ZVS Induction Heating 31mm Pitch

Description

Overview

This 0.33µF 1200V high-voltage capacitor is designed for high-frequency power electronics and resonant applications, including ZVS induction heating circuits. Its 31 mm lead pitch makes it suitable for common ZVS induction-heater PCB layouts.

The capacitor is a non-polarized film-type component intended for applications where high voltage and high-frequency operation are required. Similar 0.33µF/1200V MKPH induction-heater capacitors are available with a 31 mm lead spacing.

Key Features

• Capacitance: 0.33µF
• Rated voltage: 1200V
• MKPH high-voltage film capacitor
• 31 mm lead pitch

• Suitable for ZVS induction heating systems
• Through-hole mounting
• Compact construction for high-power electronics

Technical Specifications

Commercially available versions of this component are specifically marketed for induction cookers/furnaces and are offered in 0.33µF, 1200V, 31 mm-pitch configurations.

Applications

• ZVS induction heating circuits
• Induction heater resonant tanks
• High-frequency power converters
• Resonant switching circuits
• Induction cookers
• Induction furnaces
• High-voltage AC circuits
• RF/high-frequency power applications

ZVS Induction Heater Application

This capacitor is particularly suitable for use as part of the resonant capacitor bank in ZVS induction-heater designs. Multiple capacitors can be connected in parallel when a higher total capacitance or current capability is required.

For example, a ZVS design using six 0.33µF capacitors in parallel provides approximately:

6 × 0.33µF = 1.98µF

This configuration should be selected according to the particular induction coil, operating frequency, supply voltage, and resonant-tank design.

What’s Included

• 1 × 0.33µF 1200V High-Voltage MKPH Film Capacitor
• Lead pitch: 31 mm

Notes

• This is a non-polarized capacitor and can be installed in either orientation.
• The 1200V rating is a maximum rated voltage, not an indication that the capacitor should routinely be operated at its limit.
• For ZVS induction heating, capacitor selection should consider RMS current, pulse current, operating frequency, and thermal conditions, not voltage and capacitance alone.
• 31 mm lead pitch should be checked against the PCB footprint before assembly.
