UPS2A2R2MDD

The UPS2A2R2MDD is a miniature, low-impedance aluminum electrolytic capacitor in a radial lead can package from Nichicon’s UPS series. It is a polarized component with a rated capacitance of 2.2 µF and a rated voltage of 100 V, designed for compact power-electronic assemblies.

Targeted for switching power supplies and general-purpose electronic applications, this part combines a small footprint and 2 mm lead spacing with a wide operating temperature range (−55 °C to +105 °C) and specified ripple current ratings to address dense power layouts and thermal stress environments.

Key Features

• Electrical rating — 2.2 µF capacitance at 100 V with ±20% tolerance and polarized construction for DC power applications.
• Miniature radial can package — Radial lead mounting with 2 mm lead spacing and compact dimensions (L: 1.1 × D: 0.5 cm) for high-density board layouts.
• Low-impedance design — Specified ripple current of 7.48 mA at 120 Hz and 44 mA at 10 kHz to meet switching-power supply ripple-handling requirements.
• Wide temperature range — Rated for operation from −55 °C to +105 °C to support a broad set of environmental conditions.
• High-temperature endurance — Lifetime specified as 2000 hours at 105 °C, supporting designs with elevated operating temperatures.
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Suited to switching-regulator circuits where low impedance and rated ripple current are required for stable operation.
• General-Purpose Power Electronics — Useful across general-purpose designs that require a compact polarized capacitor with a 100 V rating.
• High-Density Power Modules — Small can size and radial lead format enable placement in tight layouts for compact power converters and modules.

Unique Advantages

• Compact footprint: Small overall dimensions (1.1 × 0.5 cm) and 2 mm lead spacing reduce board area and help optimize PCB real estate.
• High-voltage capability: 100 V rating provides margin for higher-voltage DC rails within compact power designs.
• Ripple-ready performance: Specified ripple currents at 120 Hz and 10 kHz support switching environments and help maintain stability under dynamic loads.
• Extended temperature range: −55 °C to +105 °C operation accommodates a wide variety of environmental conditions.
• Specified high-temperature lifetime: 2000 hours at 105 °C offers predictable end-of-life planning for higher-temperature applications.
• Regulatory compliance: RoHS conformity simplifies selection for designs with restricted substances requirements.
