UPA1C471MPD

The UPA1C471MPD is a radial lead aluminum electrolytic capacitor with 470 µF capacitance and a 16 V rating, designed for general-purpose power filtering and decoupling. It combines a miniature φ10×12.5 mm can with low impedance and high ripple-current capability to support compact power-supply and DC-DC converter designs.

Key attributes include a wide operating temperature range of −55 °C to 105 °C, a 4 000‑hour endurance at 105 °C, and RoHS compliance—making it suitable for designs that require reliable long-term smoothing in constrained PCB footprints.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20% for bulk energy storage and smoothing applications.
• Low Impedance — Specified impedance of 126 mΩ, supporting stable filtering performance in power rails.
• High Ripple Current Capacity — Low-frequency ripple current of 675 mA (120 Hz) and high-frequency ripple current of 900 mA (10 kHz) to handle ripple stress in switching supplies.
• Thermal & Endurance Rating — Rated for −55 °C to 105 °C operation with a 4 000‑hour life at 105 °C under rated conditions.
• Leakage & Dissipation — Leakage current specified as 225.6 µA and tan δ of 0.16 (measured at 20 °C, 120 Hz), enabling predictable loss and standby behavior.
• Compact Radial Package — φ10×12.5 mm can with 5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assembly and straightforward PCB placement.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible assembly workflows.

Typical Applications

• Switching Power Supplies — Provides output smoothing and ripple attenuation in compact SMPS modules where low impedance and high ripple capability are required.
• DC‑DC Converters — Serves as input/output bulk capacitance for point-of-load converters to stabilize voltage rails and reduce voltage transients.
• Power Filtering — Used for generalized filtering on power distribution lines in industrial and consumer electronic equipment.
• Embedded Systems — Fits space-constrained boards that require robust bulk capacitance with extended temperature and life performance.

Unique Advantages

• Compact footprint with substantial capacitance — 470 µF in a φ10×12.5 mm can lets designers preserve board space while retaining significant energy storage.
• Predictable ripple handling — Specified ripple currents at 120 Hz and 10 kHz allow designers to size parts for both low- and high-frequency switching environments.
• Long life at elevated temperature — 4 000‑hour endurance at 105 °C supports applications that require extended reliability under thermal stress.
• Clear electrical characterization — Published impedance, tan δ, and leakage current values facilitate accurate thermal and electrical margining in power designs.
• Through-hole, serviceable form factor — Radial lead mounting simplifies prototyping, repair, and replacement compared with surface-mount-only components.
• Regulatory compliance — RoHS compliance supports use in environments where lead-free materials are required.
