UPA1A182MPD

The UPA1A182MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPA series, offering 1.8 mF capacitance at a 10 V rating in a compact φ10 × 20 mm can. It combines low impedance and high ripple-current capability in a miniature package, addressing general-purpose power applications and switching power supply designs.

Designed for reliability across a wide temperature range (−55°C to 105°C) and long endurance (4000 hours at 105°C), this part is suitable where compact bulk capacitance and robust ripple handling are required.

Key Features

• Electrical Performance — 1800 µF nominal capacitance with ±20% tolerance and rated voltage of 10 V; impedance specified at 70 mΩ for stable power performance.
• Low Loss / Frequency Behavior — tan δ of 0.19 measured at 20°C, 120 Hz (10 V); frequency coefficient data included for ripple-current scaling up to 10 kHz.
• High Ripple Current Handling — Low-frequency ripple current of 1.2665 A at 120 Hz and high-frequency ripple current of 1.49 A at 10 kHz, enabling effective filtering in switching environments.
• Reliability & Endurance — Rated endurance of 4000 hours at 105°C (φ10 case), with specified limits for capacitance change, tan δ increase, and leakage current after stress.
• Wide Temperature Range — Operates from −55°C to 105°C for use across varied thermal conditions.
• Compact Radial Package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCB designs; available in bulk/bag packing.
• Environmental Compliance — RoHS compliant as specified for the UPA series.

Typical Applications

• Switching Power Supplies — Miniature, low-impedance capacitor suited to meet ripple and filtering requirements in switching converters.
• General-Purpose Electronics — Bulk capacitance and rated voltage make it suitable for general-purpose smoothing and energy storage in electronic equipment.
• Power Conversion Modules — Compact size and high ripple capability support local energy buffering in power regulation assemblies.

Unique Advantages

• High Capacitance in a Small Footprint — 1800 µF in a φ10 × 20 mm can allows designers to pack significant bulk capacitance into limited PCB area.
• Proven Ripple Performance — Specified ripple currents at both 120 Hz and 10 kHz provide clear data for thermal and reliability budgeting in power designs.
• Low Impedance — 70 mΩ impedance contributes to lower voltage ripple and improved transient response where applied.
• Long Endurance at Elevated Temperature — 4000 hours at 105°C (φ10 case) gives predictable life performance for demanding thermal environments.
• Wide Operating Temperature Range — −55°C to 105°C supports deployments across a broad set of environmental conditions.
• RoHS Compliant — Meets RoHS directive requirements as documented for the UPA series.
