UPM1C821MPD

The UPM1C821MPD is a miniature aluminum electrolytic capacitor from Nichicon's UPM series, configured as a radial lead (can) device. It delivers 820 µF capacitance at a 16 V rating with a polarized design and is intended for high-reliability applications.

Designed for demanding environments, this part combines low impedance, measurable ripple-handling capability, and extended endurance to support long-life power applications where stable bulk capacitance and temperature tolerance are required.

Key Features

• Capacitance and Voltage — 820 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, and a rated voltage of 16 V.
• Low Impedance — Rated impedance of 55 mΩ, providing effective bulk energy storage and transient support.
• Ripple Current Performance — Low-frequency ripple current 770.4 mA (120 Hz) and high-frequency ripple current 1.07 A (200 kHz), supporting both DC and higher-frequency ripple conditions.
• Leakage and Loss — Specified leakage current of 393.6 µA and tanδ of 0.16 (measured at 20°C, 120 Hz), enabling predictable loss and standby current behavior.
• High Reliability Endurance — Life rating of 5000 hours at 105°C under rated conditions, with performance limits defined for capacitance change, tanδ, and leakage current.
• Wide Operating Temperature — Specified for operation from −55°C to +105°C to accommodate broad thermal environments.
• Compact Radial Package — Can-style radial package with dimensions φ10 × 25 mm and 5 mm lead spacing (lead spacing tolerance ±0.5 mm); available in bulk or bag packing without terminal forming.
• AEC-Q200 Rating and RoHS Compliance — Provided ratings include AEC-Q200 and RoHS compliance as specified in the product data.

Typical Applications

• Automotive power systems — Suitable for use in automotive electronics where AEC-Q200 qualification, wide temperature range (−55°C to +105°C), and long endurance (5000 h at 105°C) are required.
• Vehicle control modules — Bulk energy storage and decoupling on 16 V rails benefiting from the part's 820 µF capacitance and low impedance (55 mΩ).
• High-reliability power rails — Filtering and smoothing on power supplies that require predictable leakage behavior (393.6 µA) and rated ripple handling at both low and high frequencies.

Unique Advantages

• Proven endurance — 5000-hour life at 105°C provides a verifiable reliability baseline for long-life systems.
• High ripple capability — Specified low- and high-frequency ripple current ratings (770.4 mA and 1.07 A) support mixed-frequency power environments.
• Compact, serviceable package — φ10 × 25 mm radial can with 5 mm lead spacing eases placement in space-constrained assemblies while maintaining serviceable leads.
• Low impedance for transient support — 55 mΩ impedance helps improve transient response and voltage stability on supply rails.
• Traceable compliance — AEC-Q200 rating and RoHS compliance documented in the product data support regulated and automotive design requirements.
