UPW1C821MPD

The UPW1C821MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UPW series, designed for high-reliability power-filtering and decoupling in compact electronic systems. It combines a high nominal capacitance with low impedance and ratings targeted at demanding operating conditions.

Typical use cases include switching power supplies and automotive electronic modules where compact size, sustained ripple handling and long endurance at elevated temperature are required.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of −20% to +20%.
• Low Impedance & Loss — Specified impedance of 104 mOhm and tan δ (DF) of 0.16 measured at 20°C, 120 Hz, supporting efficient power filtering.
• Ripple Current Capability — Low-frequency ripple current 915 mA (120 Hz) and high-frequency ripple current 1.22 A (10 kHz), suitable for switching regulator outputs and DC bus decoupling.
• High Reliability Endurance — Rated for 5000 hours at 105°C, supporting sustained performance in elevated-temperature environments.
• Wide Temperature Range — Operating range from −55°C to 105°C for use across broad environmental conditions.
• Compact Radial Can Package — φ10 × 20 mm can with 5.0 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies; available in bulk or bag packing.
• Leakage Current — Specified leakage current of 393.6 µA after rated voltage application, consistent with electrolyte capacitor performance expectations.
• AEC-Q200 Rated — Component rated to AEC-Q200 for reliability screening appropriate to automotive and other high-reliability applications.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where 820 µF in a compact φ10×20 mm package delivers stable decoupling under ripple loads.
• Automotive Electronics — Power rail smoothing and transient suppression in modules that require AEC-Q200-rated components and extended high-temperature endurance.
• DC-DC Converters and Regulators — Local decoupling for converters that demand low impedance and high ripple current handling at both low and high frequencies.

Unique Advantages

• High Capacitance in a Small Footprint: 820 µF in a φ10×20 mm can supports compact board layouts without sacrificing capacitance.
• Robust Ripple Handling: Rated ripple currents of 915 mA (120 Hz) and 1.22 A (10 kHz) address both low- and high-frequency switching artifacts.
• Long Endurance at Elevated Temperature: 5000 hours at 105°C provides predictable lifetime for designs exposed to sustained heat.
• Low Impedance and Controlled Loss: 104 mOhm impedance and tan δ = 0.16 (20°C, 120 Hz) improve voltage stability on power rails.
• Automotive-Grade Screening: AEC-Q200 rating supports use in reliability-focused applications and development workflows that require screened passives.
• Standard Radial Mounting: 5.0 mm lead spacing and radial can packaging simplify through-hole assembly and replacement processes.
