UPA1E821MPD

The UPA1E821MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPA series designed for high-reliability power applications. It combines a compact φ10×20 mm can with low impedance and robust ripple-handling to support demanding power circuitry.

Suited for switching power supplies and general-purpose power designs, this 820 µF, 25 V polarized capacitor delivers measurable performance advantages—low impedance (70 mΩ), substantial ripple current capacity, a wide operating temperature range (−55°C to 105°C) and a 4,000-hour endurance rating at 105°C.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20% for predictable bulk energy storage.
• Low Impedance — Rated impedance of 70 mΩ supports efficient filtering and transient response in power rails.
• High Ripple Current — Handles 1.117 A at 120 Hz (low frequency) and 1.49 A at 10 kHz (high frequency), enabling effective AC ripple suppression across common frequencies.
• Compact Radial Package — φ10×20 mm can with 5 mm lead spacing and radial-lead mounting for through-hole PCB applications.
• Reliability & Endurance — Life rating of 4,000 hours at 105°C under rated conditions, supporting long-term operation in elevated-temperature environments.
• Electrical Loss and Leakage — Tangent of loss angle (tan δ) 0.14 (measured at 20°C, 120 Hz) and specified leakage current of 615 µA.
• Wide Temperature Range — Operates across −55°C to 105°C to accommodate a broad set of environmental conditions.
• RoHS Compliant — Meets RoHS environmental requirements.

Typical Applications

• Switching Power Supplies — Miniature, low-impedance bulk capacitance for smoothing and energy buffering in switch-mode power architectures.
• General-Purpose Power Circuits — Bulk decoupling and energy storage in a variety of consumer and industrial power designs where through-hole radial mounting is preferred.
• High-Reliability Electronics — Applications requiring operation across −55°C to 105°C and extended endurance at elevated temperature.

Unique Advantages

• Compact energy density — 820 µF in a φ10×20 mm package delivers substantial capacitance in a small footprint for space-constrained boards.
• Measured low impedance — 70 mΩ impedance improves ripple attenuation and transient performance compared to higher-impedance alternatives.
• High ripple capability across frequencies — Specified ripple currents at 120 Hz and 10 kHz (1.117 A and 1.49 A) provide effective performance from low to high switching frequencies.
• Extended high-temperature life — 4,000-hour endurance at 105°C supports reliable operation in thermally demanding designs.
• Robust operating range — −55°C to 105°C allows deployment in diverse environmental conditions without derating outside specified limits.
• Regulatory compliance — RoHS compliance supports environmental requirements for modern electronics manufacturing.
