UPS2A3R3MDD

The UPS2A3R3MDD is a miniature radial aluminum electrolytic capacitor in Nichicon's UPS series, optimized for low-impedance power applications. It delivers 3.3 µF capacitance at a 100 V rating in a compact φ5 × 11 mm can and is intended for general-purpose use including switching power supply designs.

Key attributes include a wide operating temperature range (−55°C to 105°C), RoHS compliance, and construction suited to space-constrained power filtering and decoupling tasks.

Key Features

• Capacitance and Tolerance — 3.3 µF nominal capacitance with a tolerance of −20% to +20% (±20% at 120 Hz, 20°C), providing predictable filtering performance.
• High Voltage Rating — Rated to 100 V, allowing use in higher-voltage rails and power-supply stages where elevated DC bias is present.
• Low Loss — Tangent of loss angle (tanδ) of 0.08 measured at 20°C, 120 Hz, supporting efficient energy handling with lower dissipation.
• Ripple Current Performance — Specified low-frequency ripple current of 9.86 mA at 120 Hz and high-frequency ripple current of 58 mA at 10 kHz, useful for both mains-frequency and switching-frequency ripple suppression.
• Leakage Current — Leakage current specified at 9.9 µA, enabling reliable DC filtering with minimal bleed.
• Temperature and Endurance — Rated for operation from −55°C to +105°C with an endurance rating of 2000 hours at 105°C.
• Compact Radial Package — Radial-lead can measuring φ5 × 11 mm with 2.0 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Polarized — Conventional polarized aluminum electrolytic design for DC power applications.
• RoHS Compliant — Manufactured in compliance with RoHS standards.

Typical Applications

• Switching Power Supplies — Local decoupling and output filtering in compact switch-mode power supply circuits where miniature low-impedance capacitors are required.
• Power Rail Decoupling — Smoothing and transient suppression on higher-voltage DC rails up to 100 V.
• Space-Constrained Power Modules — Fits compact, densely populated PCBs thanks to its φ5 × 11 mm footprint and radial-lead mounting.

Unique Advantages

• Compact Footprint: The φ5 × 11 mm can and radial lead form factor minimize board area for power-filtering components.
• High Voltage Capability: 100 V rating supports higher-voltage DC applications without series stacking.
• Temperature Robustness: Specified operation from −55°C to +105°C enables use across a wide thermal range.
• Measurable Ripple Handling: Defined ripple current values at both 120 Hz and 10 kHz help designers size capacitors for expected operating frequencies.
• Predictable Loss and Leakage: Low tanδ (0.08) and 9.9 µA leakage provide transparent electrical characteristics for power-budget planning.
• RoHS Compliance: Meets environmental regulatory requirements for restricted substances.
