The MMKP82 capacitor is a double-sided metallized polypropylene film capacitor with a unique three-layer internal structure:
Top layer——DMPET film (double-sided metallized polypropylene film)
Middle layer——PP base film (non-metallized "bare" film)
Bottom layer——MPP double-sided metallized film with margin
Due to its double-sided metallization process and specialized winding machinery, it offers superior high-voltage resistance, high-frequency performance, and high-current handling compared to standard CBB capacitors (single-sided metallization).
The MMKP82 capacitor functions similarly to the CBB81 but with enhanced performance, making it suitable for:
High-frequency, high-voltage pulse circuits
Household appliance power supplies, industrial frequency converters, and inverter power supplies
RC step-down circuits
SCR rectifier circuits and snubber circuits
Electronic ballasts and energy-saving lamps
Inverters, energy storage systems, and GaN PD fast chargers
Smaller size, saving space
Better resistance to high temperatures and moisture
Longer lifespan and higher stability
Lower loss and reduced internal temperature rise
Negative capacitance temperature coefficient
Excellent flame-retardant properties
Higher rated voltages (250V/400V/630V/1000V/1250V/1600V/2000V DC)
The MMKP82 capacitor is an upgraded version of the CBB81, offering superior performance at a slightly higher cost. It is widely used in:
High-voltage, high-frequency environments (e.g., switch-mode power supplies, inverters)
Pulse circuits (e.g., inverters, energy storage systems)
Fast-charging devices (e.g., GaN PD chargers)
Industrial power electronics (e.g., SCR rectification, snubber circuits)
Due to its double-sided metallized construction, the MMKP82 capacitor outperforms standard CBB capacitors in voltage resistance, high-frequency stability, and reliability, making it an ideal choice for high-performance circuits, especially in high-voltage, high-frequency, and pulse applications.
