Product Overview

The CBB21/MPP series metallized polypropylene film capacitor is an epoxy-encapsulated, non-inductive wound type capacitor. It features a self-healing capability due to its metallized polypropylene film construction and a low loss design, resulting in minimal internal temperature rise. The capacitor is encapsulated with flame-retardant epoxy resin powder. It is widely used in DC blocking, coupling, decoupling, filtering, bypassing, and other high-frequency, DC, AC, and pulse circuits in electronic equipment.

Technical Specifications

General Electrical Characteristics

Maximum dV/dt Values

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.

Product Structure and Main Materials

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

Packaging Information

Carton Packaging Details:

• Includes manufacturer part number, number of packages, quantity per package, and Lot No.
• Capacitors are packed in transparent PVC bags for moisture and dust protection.
• RoHS environmental mark is applied.
• Other customer marking requirements can be accommodated.

Storage Conditions

• Prolonged exposure to air may degrade lead solderability.
• Avoid high temperature and high humidity environments.
• Recommended Storage Conditions (in original packaging):
• Temperature: Max 35
• Relative Humidity: Max 80%
• Storage Time: Maximum 12 months (based on production date marked on the packaging bag).

Usage Rules

• Usage Range:
• Do not exceed the upper limit category temperature during use.
• Avoid overload operation.
• Do not exceed the maximum pulse current during use.
• Handling Precautions:
• Avoid repeated squeezing at the lead root.
• Be mindful of the lead tip.
• Soldering:
• Solder heat can transfer to the capacitor core through lead terminals and encapsulation layers. Care must be taken to avoid degradation or damage due to high temperatures and prolonged soldering times.
• Wave Soldering: TP 110 for 120 seconds; Ts 120 for 45 seconds. For MPP capacitors with P 7.5mm and T 4mm, soldering time should be < 4 seconds.
• Soldering Iron: Tip temperature should not exceed 350, and soldering time should not exceed 3 seconds.
• Lead-type film capacitors are not suitable for reflow soldering.
• Ts: Maximum temperature the capacitor body can withstand during wave soldering.
• Tp: Maximum preheating temperature the capacitor body can withstand.

Maximum Effective Voltage vs. Frequency Curve

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