CAP-XX DMT220mF supercapacitor - compact pulsed energy in surface mount

The CAP-XX DMT220mF supercapacitor is a state-of-the-art SMD-class solution designed for integration into space-constrained devices that require fast pulsed energy delivery. Thanks to DMR (Dual Mount Reflowable) technology, this supercapacitor can be safely assembled using a standard reflow soldering process, significantly simplifying the manufacturing process and reducing assembly costs.

Key features:

• capacitance: 220 mF - optimum energy support for short duration pulses
• voltage rating: 2.7 V
• low ESR: 180 mΩ (typical) - efficient power delivery with low resistance
• dimensions: only 21 × 14 × 2.3 mm - ideal for miniature devices
• SMD housing with reflow soldering: simplified PCB mounting
• operating temperature range: -40°C to +85°C - proven reliability in industrial environments
• high durability: more than 500,000 charge and discharge cycles
