Product Overview

The CBB21/MPP series metallized polypropylene film capacitors are designed for electronic equipment applications. These capacitors feature a non-inductive winding structure with a flame-retardant epoxy resin powder encapsulation. They are suitable 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 low internal temperature rise.

Usage Rules

• Usage Range: Do not exceed the upper category temperature. Avoid overload. Do not exceed maximum pulse current.
• Handling Precautions: Avoid repeated squeezing at the lead root. Pay attention to the lead tips.
• Soldering: Solder heat can transfer to the capacitor core. Be mindful of potential damage from high temperatures and prolonged soldering times.
• Soldering Temperature Limits:
  • Wave Soldering (MPP Polypropylene Film Capacitors): TP 110 for 120 seconds; Ts 120 for 45 seconds. For P7.5mm, T4mm, wave soldering time < 4 seconds.
  • Soldering Iron: Tip temperature not exceeding 350, time not exceeding 3 seconds.
  • Film capacitors with leads are not suitable for reflow soldering.
