Product Overview

The CBB21/MPP series metallized polypropylene film capacitors are designed for electronic equipment, featuring an epoxy encapsulated, non-inductive winding structure. These capacitors are suitable for DC blocking, coupling, decoupling, filtering, bypassing, and other high-frequency, DC, AC, and pulse circuits. They offer excellent self-healing properties, low loss, and low internal temperature rise, with a flame-retardant epoxy resin powder coating.

Technical Specifications

General Electrical Characteristics

Maximum Pulse Rise Rate (dV/dt)

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

Product Structure and Main Materials

Note: All raw materials and finished products comply with RoHS environmental requirements.

Electrical Characteristics Testing

Usage Rules

• Scope of Use: Do not exceed the upper limit category temperature. Avoid overload. Do not exceed the maximum pulse current.
• Handling Precautions: Avoid repeatedly squeezing the lead wire root. Be mindful of the lead wire tip.
• Soldering: Solder heat can transfer to the capacitor core through lead terminals and encapsulation layers. Be cautious of capacitor electrical characteristic degradation or damage caused by high temperatures and prolonged soldering.
• Soldering Temperature Ranges:
  • 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
  • Soldering Iron: Tip temperature not exceeding 350, time not exceeding 3 seconds.
  • Lead film capacitors are not suitable for reflow soldering.
• Ts: Maximum temperature the capacitor body can withstand during wave soldering.
• Tp: Maximum temperature the capacitor body can withstand during the preheating stage.

Maximum Effective Voltage vs. Frequency Curve

Note: Curve values are typical and tested under conditions of sinusoidal voltage, ambient temperature 85, and internal capacitor temperature rise T = 10.
