Product Overview

The CBB21/MPP series metallized polypropylene film capacitors (impregnated type) are designed for electronic equipment with flame-retardant epoxy encapsulation. These capacitors feature a non-inductive winding structure with metallized polypropylene film and tinned copper wire or tinned copper-clad steel wire leads. They are widely used for DC blocking, coupling, decoupling, filtering, bypassing, and other high-frequency, DC, AC, and pulse circuits. Key advantages include excellent self-healing properties, low loss, and minimal internal temperature rise, all housed in a flame-retardant epoxy resin powder coating.

General Electrical Characteristics

Maximum Pulse Rise Time (dV/dt)

Note: If the actual working voltage (U) is lower than the rated voltage (UR), the capacitor can operate at a higher dV/dt. The allowable dV/dt value should be multiplied by UR/U.

Detailed Electrical Characteristics and Test Methods

Usage Rules

• Usage Range:
• Do not exceed the upper category temperature during use.
• Avoid overload operation.
• Do not exceed the maximum pulse current during use.
• Operational Precautions:
• Avoid repeatedly squeezing the base of the leads.
• Pay attention to the tips of the leads.
• Soldering: Solder heat can transfer to the capacitor core through the lead terminals and encapsulation layer. Therefore, be cautious of capacitor electrical characteristic degradation or damage caused by high temperatures and prolonged soldering.
• Confirmed Solder Temperature Range:
• (1) Wave Soldering for MPP Polypropylene Film Capacitors: TP 110 for 120 seconds; Ts 120 for 45 seconds. For P 7.5mm, T 4mm, wave soldering time < 4 seconds.
• (2) When using an iron soldering, the iron tip temperature should not exceed 350, and the soldering time should not exceed 3 seconds.
• (3) Film capacitors with leads are not suitable for reflow soldering.
• Ts: Maximum temperature the component body can withstand during wave soldering.
• Tp: Maximum temperature the component body can withstand during the preheating stage.

Maximum Effective Voltage vs. Frequency Curve

Note: The typical values in the curve are tested under conditions of sinusoidal voltage, ambient temperature 85, and internal temperature rise T=10.
