UPA0J102MPD

The UPA0J102MPD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon's UPA series, designed for high‑reliability power filtering in switching power supplies and general‑purpose circuits. It delivers low impedance and high ripple‑current capability in a compact, polarized radial can package.

Key value propositions include lower impedance than the UPW series, a small case footprint (L: 1.5 × D: 0.8 cm), and RoHS compliance for environmentally conscious designs.

Key Features

• Electrical Performance — 1 mF capacitance with a 6.3 V rated voltage and impedance of 124 mΩ, suitable for power‑filtering and decoupling tasks.
• High Ripple Current — Rated ripple current of 645 mA at 120 Hz and 860 mA at 10 kHz, supporting effective smoothing under switching conditions.
• Compact Radial Can — Radial, can‑style package with 3.5 mm lead spacing and radial lead mounting for through‑hole PCB layouts.
• Reliability & Lifetime — Operates across −55 °C to +105 °C with a rated lifetime of 3000 hours at 105 °C for the φ8 case size.
• Polarized Construction — Polarized electrolyte design for standard DC filtering applications.
• Manufacturing & Compliance — Part of Nichicon’s UPA series with RoHS compliance (2011/65/EU, (EU)2015/863).
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20 °C for predictable performance in designed circuits.
• Leakage Current Specification — After 1 minute at rated voltage and 20 °C, leakage current not more than 0.03CV or 4 μA, whichever is greater (series characteristic).

Typical Applications

• Switching Power Supplies — Provides low‑impedance bulk and output filtering where high ripple current handling and compact size are required.
• General Purpose Power Filtering — Suited for DC smoothing and decoupling in a wide range of electronic equipment.
• Power Conversion Modules — Useful in compact converter designs needing reliable ripple suppression and thermal endurance.

Unique Advantages

• Low Impedance at Size — 124 mΩ impedance combined with a small case footprint reduces board area without sacrificing filtering effectiveness.
• High-Frequency Ripple Capability — 860 mA rated ripple current at 10 kHz supports modern switching frequencies and minimizes voltage ripple under load.
• Extended Temperature Range — Wide operating range from −55 °C to +105 °C enables use across diverse environmental conditions.
• Designed for Long High‑Temperature Life — 3000‑hour endurance at 105 °C (φ8 case) for sustained reliability in thermally demanding applications.
• RoHS Compliant — Meets regulatory requirements for restricted substances to support environmentally conscious manufacturing.
• Through‑Hole, Easy Integration — Radial lead spacing (3.5 mm) and can package simplify PCB layout and assembly for through‑hole designs.
