UPJ1A822MHD

The UPJ1A822MHD is a radial-leaded aluminum electrolytic capacitor from Nichicon's UPJ series, designed for low impedance and reliable performance in power circuits. It provides 8.2 mF (8200 µF) capacitance at a 10 V rating and is intended for general-purpose use, with specific suitability for switching power supplies.

Key attributes include a wide operating temperature range of −55°C to 105°C, a rated endurance of 5000 hours at 105°C, and RoHS compliance—making it a durable choice for through-hole power filtering and energy-storage applications where sustained ripple handling and long life are required.

Key Features

• Capacitance & Voltage: 8.2 mF (8200 µF) rated at 10 V with ±20% tolerance measured at 120 Hz, 20°C—suitable for substantial bulk capacitance in low-voltage rails.
• Low Impedance Design: UPJ-series low-impedance construction tailored for switching power supplies, supporting efficient smoothing and decoupling under switching conditions.
• High Ripple Current Capability: Low-frequency ripple current 2.277 A (120 Hz) and high-frequency ripple current 2.53 A (200 kHz), enabling effective handling of both mains-frequency and switching-frequency ripple.
• Reliability & Endurance: Load life rated 5000 hours at 105°C; endurance specifications include capacitance change within ±20% and controlled tan δ and leakage current after life test.
• Electrical Loss (tan δ) & Leakage: Specified tan δ (DF) 0.33 at 20°C, 120 Hz and measured leakage current 2460 µA for the part as specified.
• Mechanical & Mounting: Radial lead (can) package, size φ16×40 mm, lead spacing 7.5 mm (±0.5 mm), suitable for through-hole PCB mounting and bulk or bag packing.
• Environmental Compliance: RoHS compliant.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output decoupling where low impedance and high ripple handling are required for stable regulation.
• Power Supply Filtering: General-purpose DC filtering on low-voltage rails to reduce ripple and provide energy reserve for transient loads.
• Embedded and Industrial Electronics: Through-hole power modules and assemblies that require robust electrolytic capacitance with extended high-temperature endurance.

Unique Advantages

• High Capacitance in a Compact Can: 8200 µF in a φ16×40 mm radial package provides substantial bulk energy storage while preserving PCB real estate compared with larger form factors.
• Designed for Switching Environments: Low-impedance UPJ series construction and specified high-frequency ripple rating (2.53 A at 200 kHz) improve performance in switching regulator outputs.
• Extended High-Temperature Life: Rated 5000 hours at 105°C for long-term reliability in thermally demanding designs.
• Through-Hole Mounting Convenience: Radial lead format with 7.5 mm lead spacing simplifies manual assembly and wave/soldering processes for PCB designs that use can-style electrolytics.
• Regulated Loss and Leakage Parameters: Specified tan δ and leakage current figures enable predictable behavior for designers balancing ESR/DF and leakage budgets in power systems.
• RoHS Compliance: Meets RoHS requirements for electronics products and assemblies.
