UPA1A102MPD

The UPA1A102MPD is a miniature radial aluminum electrolytic capacitor from Nichicon’s UPA series designed for switching power supply and general-purpose power applications. It combines low impedance, compact radial-can packaging, and high ripple-current capability to support dense power designs.

Key electrical characteristics include 1 mF capacitance at 10 V, low impedance (88 mΩ), and rated operation across –55°C to +105°C, with RoHS compliance for environmental assurance.

Key Features

• Capacitance and Voltage: 1 mF capacitance rated at 10 V, with ±20% tolerance (at 120 Hz, 20°C) for predictable filtering and energy storage.
• Low Impedance: Specified impedance of 88 mΩ for reduced ripple voltage and improved transient response in power rails.
• High Ripple Current Handling: Rated ripple current of 915 mA at 120 Hz and 1.22 A at 10 kHz to support switching supply ripple and decoupling needs.
• Thermal and Lifetime Performance: Operating temperature range –55°C to +105°C with a rated life of 3000 hours at 105°C, supporting reliable operation under elevated temperature stress.
• Radial Can Package: Radial lead mounting, 3.5 mm lead spacing and compact footprint (L: 2 cm × D: 0.8 cm) for through-hole PCB assemblies.
• Leakage Current Specification: Leakage current after one minute at 20°C is specified as not more than 0.03CV or 4 µA, whichever is greater.
• Regulatory Compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies: Low impedance and high ripple-current capability make it suitable for output filtering and bulk decoupling in switch-mode regulators.
• General Power Filtering: Compact radial-can form and 1 mF capacitance support smoothing and energy storage in a variety of compact power modules.
• Industrial and Commercial Electronics: Robust temperature range and rated lifetime at 105°C provide reliable performance in elevated-temperature environments common to industrial equipment.

Unique Advantages

• Compact, High‑Performance Package: Small radial-can dimensions deliver 1 mF capacitance and low impedance without a larger footprint, aiding PCB space savings.
• Improved Ripple Handling: Measured ripple current ratings at both low (120 Hz) and high (10 kHz) frequencies enable effective suppression of switching noise across common regulator frequencies.
• Temperature and Lifetime Confidence: Rated for –55°C to +105°C with a specified 3000 hours at 105°C, helping designs meet durability expectations under thermal stress.
• Predictable Leakage Behavior: Clear leakage current specification (0.03CV or 4 µA threshold) simplifies power-loss and standby-current budgeting.
• RoHS Compliant: Meets applicable RoHS directives, supporting regulatory needs for commercial and industrial products.
