UPA1A102MPD3

The UPA1A102MPD3 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPA series. It is a radial-lead, polarized capacitor rated 10 V with 1000 µF capacitance and a ±20% tolerance.

Engineered for switching power supplies and general-purpose power filtering in compact electronic designs, this part combines low impedance and high ripple-current capability with long endurance at elevated temperature to support robust power-rail decoupling and smoothing.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance at a rated voltage of 10 V with a tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 98 mΩ for efficient AC filtering and energy storage in power circuits.
• High Ripple-Current Performance — Low-frequency ripple current 930 mA at 120 Hz and high-frequency ripple current 1.24 A at 10 kHz to handle switching ripple across a wide spectrum.
• Loss Characteristics — Dissipation factor (tan δ) of 0.19 (measured at 20°C, 120 Hz) for predictable AC loss behavior.
• Leakage Current — Leakage current specified at 300 µA for controlled standby leakage in power applications.
• Long Endurance — Rated life of 4000 hours at 105°C for sustained operation under elevated-temperature conditions.
• Compact Radial Package — φ10 × 16 mm can with 5 mm lead spacing and radial-lead mounting for through-hole PCB assemblies.
• Wide Operating Temperature — −55°C to +105°C operating range to cover a broad set of environmental conditions.
• Compliance & Availability — RoHS compliant and in mass production; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Switching Power Supplies — Smoothing and bulk energy storage to reduce output ripple and support transient load changes.
• General-Purpose Power Filtering — Decoupling and filtering on low-voltage rails in compact electronic equipment.
• Compact and Embedded Systems — Space-efficient radial can (φ10×16 mm) suited to designs where board real estate and reliable ripple performance are required.

Unique Advantages

• Effective Noise and Ripple Suppression: Low impedance (98 mΩ) combined with defined tan δ delivers predictable AC filtering performance for power-stage decoupling.
• High Ripple Handling: Specified ripple currents of 930 mA (120 Hz) and 1.24 A (10 kHz) let you design for both low- and high-frequency switching environments.
• Compact, Through-Hole Form Factor: φ10×16 mm radial can with 5 mm lead spacing provides a small footprint while retaining through-hole mechanical robustness.
• Endurance at Elevated Temperature: 4000-hour rating at 105°C supports long-term reliability in thermally demanding applications.
• Controlled Leakage and Loss: Defined leakage current (300 µA) and tan δ (0.19) help maintain predictable standby and AC behavior in power designs.
• Regulatory Compliance: RoHS compliance for environmental and regulatory alignment in modern production environments.
