UPA1C821MPD

The UPA1C821MPD is a radial lead aluminum electrolytic capacitor in Nichicon’s UPA series, offering a compact φ8×20 mm can for general-purpose power filtering and decoupling. Designed for switching power supplies and other power-electronics applications, it combines low impedance with high ripple-handling capability and extended high-temperature endurance.

Key characteristics include 820 µF capacitance at 16 V, a wide operating temperature range from −55°C to 105°C, and series-level attributes such as reduced impedance and high ripple current suitable for bulk and decoupling roles in compact power designs.

Key Features

• Capacitance and Voltage — 820 µF nominal capacitance with a 16 V rated voltage and tolerance of −20% to +20%, providing stable bulk capacitance for low-voltage power rails.
• Low Impedance — Specified impedance of 88 mΩ, supporting effective smoothing and transient handling in power supply circuits.
• High Ripple Current Capability — Low-frequency ripple current 915 mA (120 Hz) and high-frequency ripple current 1.22 A (10 kHz), enabling robust performance across typical switching and filtering frequencies.
• Compact Radial Can — φ8×20 mm can with 3.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assembly in tight layouts.
• Endurance and Temperature Range — Rated for 3000 hours at 105°C and an operating range of −55°C to 105°C, supporting long-term reliability in thermally demanding environments.
• Loss Tangent and Leakage — tan δ of 0.16 (measured at 20°C, 120 Hz) and specified leakage current of 393.6 µA, allowing predictable dissipation and standby characteristics.
• Compliance and Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Switching Power Supplies — Bulk capacitance and low impedance help smooth output rails and absorb switching ripple in compact PSU designs.
• DC‑DC Converters — Provides energy storage and transient suppression on input/output rails where space is constrained and high ripple capability is required.
• Industrial and Consumer Power Filtering — General-purpose decoupling and smoothing for embedded controllers, power modules, and analog front-ends operating across −55°C to 105°C.

Unique Advantages

• Compact footprint with high capacitance: 820 µF in a φ8×20 mm radial can enables higher bulk capacitance in space‑limited boards.
• Improved ripple handling across frequencies: Rated ripple currents up to 1.22 A at 10 kHz and 915 mA at 120 Hz support both low- and high-frequency power stresses.
• Low impedance for stable rails: 88 mΩ impedance reduces voltage sag under load and improves transient response for power-sensitive circuits.
• Extended high‑temperature endurance: 3000 hours at 105°C provides predictable lifetime performance in elevated-temperature assemblies.
• Wide operating range: −55°C to 105°C rating covers a broad set of environmental conditions for general-purpose electronics.
• RoHS compliant and production‑ready: Conforms to RoHS and is available in bulk or bag packing for volume assembly.
