UPA1A332MHD

The UPA1A332MHD is a radial lead aluminum electrolytic capacitor in Nichicon’s UPA series, offering 3300 µF capacitance at a 10 V rating. Designed for general-purpose power filtering and switching power supply applications, it delivers low impedance and high ripple-current capability in a compact φ12.5 × 25 mm can.

Built for reliability in demanding thermal environments, the part is specified for operation from −55 °C to +105 °C and an endurance of 5000 hours at 105 °C for the φ12.5 case size. It is RoHS compliant and supplied in bulk/bag packing for volume production use.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) rated at 10 V for bulk energy storage and decoupling in low-voltage power rails.
• Low Impedance — Rated impedance of 44 mΩ supports low-loss filtering and improved transient response in power conversion circuits.
• High Ripple Current — Ripple current handling of 1.938 A at 120 Hz and 2.28 A at 10 kHz, enabling effective smoothing in both low- and high-frequency converter outputs.
• Thermal Endurance — 5000 hours rated life at 105 °C for the φ12.5 case size, supporting long-term reliability under elevated temperature stress.
• Wide Operating Temperature — Specified from −55 °C to +105 °C for use across industrial and commercial temperature ranges.
• Through-Hole Radial Package — Radial lead, polarized can with 5 mm lead spacing for simple through-hole assembly and robust mechanical mounting.
• Leakage & Loss Characteristics — Leakage current limited to 0.03CV or 4 μA (whichever is greater) after 1 minute at 20 °C; tan δ limits defined per rated voltage and capacitance per series datasheet.
• Compliance — RoHS compliant for use in regulated supply chains.

Typical Applications

• Switching Power Supplies — Output smoothing and bulk decoupling where low impedance and high ripple capability improve voltage stability and converter performance.
• Power Rail Decoupling — Bulk energy storage and transient suppression on low-voltage DC rails in embedded and industrial systems.
• Industrial Control Electronics — Filtering and energy buffering in control modules that require extended endurance at elevated temperatures.
• Consumer and Commercial Equipment — General-purpose power filtering in devices that benefit from compact, high-capacitance through-hole components.

Unique Advantages

• Compact, High-Capacity Package: 3300 µF in a φ12.5 × 25 mm radial can provides significant bulk capacitance while conserving board area.
• Low-Impedance Performance: 44 mΩ impedance reduces power loss and improves transient response in power conversion and decoupling roles.
• High Ripple Handling: Specified ripple currents at 120 Hz and 10 kHz support both low- and high-frequency filtering needs without undue stress on the capacitor.
• Long Endurance at Elevated Temperature: 5000-hour life at 105 °C for the φ12.5 case size supports reliability in thermally demanding applications.
• Through-Hole Robustness: Radial lead construction with 5 mm lead spacing simplifies assembly and provides durable mechanical mounting for heavier boards or vibration environments.
• Regulatory Compliance: RoHS-compliant construction simplifies integration into regulated production environments.
