UPA1A821MPD6

The UPA1A821MPD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPA series. It is a radial-lead, polarized capacitor specified at 820 µF and 10 V, designed for compact power supply and general-purpose applications.

Engineered for low impedance and high ripple handling in a small φ10 × 12.5 mm can, this component targets switching power supplies and space-constrained power circuits that require long endurance and stable performance across a wide temperature range.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 10 V and tolerance of −20% to +20% for bulk energy storage and decoupling.
• Low Impedance — Rated impedance of 126 mΩ, supporting lower voltage ripple and improved transient response in power rails.
• High Ripple Current Capability — Handles 675 mA at 120 Hz (low frequency) and 900 mA at 10 kHz (high frequency), enabling robust performance under varying switching conditions.
• Electrical Loss (tan δ) — Loss tangent (tan δ) of 0.19 measured at 20°C and 120 Hz, reflecting controlled dielectric loss at the rated voltage.
• Long Endurance — Rated life of 4000 hours at 105°C, providing durability for continuous high-temperature operation.
• Wide Operating Temperature — Specified to operate from −55°C to +105°C for reliability across demanding thermal environments.
• Compact Radial Package — φ10 × 12.5 mm can with 5.0 mm lead spacing (±0.5 mm), offered in bulk or bag packing for flexible assembly options.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• Switching Power Supplies — Used for output smoothing and bulk decoupling where low impedance and high ripple current capability improve regulation and reduce noise.
• Power Filtering in DC‑DC Converters — Serves as input/output filter capacitance to stabilize converters in compact power modules.
• General-Purpose Electronic Equipment — Suitable for a wide range of general-purpose circuits that require compact bulk capacitance with stable performance over temperature.
