UPA1C122MPD

The UPA1C122MPD is a miniature, high‑reliability aluminum electrolytic capacitor in Nichicon’s UPA series, supplied in a radial‑lead can. Designed for power applications, it targets switching power supplies and general‑purpose power circuitry that require low impedance and elevated ripple handling in a compact footprint.

With a 1.2 mF capacitance at 16 V, low impedance and rated endurance at elevated temperature, this part delivers stable filtering and energy buffering where space is limited and long operating life is required.

Key Features

• Capacitance & Voltage — 1,200 µF nominal capacitance at a rated voltage of 16 V with a tolerance of −20% to +20%.
• Low impedance — Specified impedance of 70 mΩ supports effective smoothing and transient handling in power rails.
• High ripple current capability — Rated ripple currents of 1.266 A at 120 Hz and 1.49 A at 10 kHz for improved performance in switching environments.
• Loss factor (tan δ) — tan δ = 0.16 measured at 20°C, 120 Hz, matching the part’s 16 V rating.
• Wide temperature and endurance — Operating range −55°C to +105°C with a lifetime/endurance rating of 4000 hours at 105°C.
• Compact radial package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm), radial‑lead mounting for through‑hole assembly; available in bulk or bag packing (no terminal forming).
• Leakage current — Specified leakage current of 576 µA.
• Regulatory status — RoHS compliant and in mass production.

Typical Applications

• Switching power supplies — Low impedance and high ripple current make this capacitor suitable for output smoothing and bulk decoupling in switching regulators.
• General‑purpose power circuits — Reliable energy storage and filtering for a variety of board‑level power tasks where space is constrained.
• Compact electronic modules — Small φ10×20 mm footprint supports use in compact or space‑restricted designs requiring elevated temperature endurance.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 1.266 A (120 Hz) and 1.49 A (10 kHz) provide robust handling of switching noise and load transients.
• Low ESR/impedance: 70 mΩ impedance improves power‑rail stability and reduces voltage ripple under load.
• Compact, radial form factor: φ10 × 20 mm can with standard 5 mm lead spacing offers a small‑footprint through‑hole option for board designers.
• Extended temperature and life rating: −55°C to +105°C operating range and 4000 hours endurance at 105°C support long service life in elevated‑temperature environments.
• Production readiness: RoHS compliant and available in mass production with bulk and bag packing for volume assembly.
