UPJ0J821MPD

The UPJ0J821MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPJ series. It delivers 820 µF capacitance at a 6.3 V rating in a compact φ8 × 20 mm can with 3.5 mm lead spacing.

Designed for general-purpose power applications and the UPJ series’ low-impedance characteristics, this part is suited to smoothing, filtering and bulk energy storage in switching power supplies and other power-regulation circuits that require reliable ripple handling and extended endurance at elevated temperatures.

Key Features

• Capacitance & Voltage — 820 µF nominal with ±20% tolerance at 120 Hz, rated for 6.3 V operation.
• Low Dissipation Factor — tanδ (DF) 0.22 measured at 20°C, 120 Hz, for efficient energy handling in power circuits.
• Ripple Current Capability — Low-frequency ripple current 482.4 mA (120 Hz) and high-frequency ripple current 670 mA (200 kHz) for improved smoothing under dynamic loads.
• Leakage Current — Specified leakage current of 154.98 µA after initial application of rated voltage at 20°C.
• Endurance — Rated for 3000 hours at +105°C (φ8 case size), supporting long-term operation in elevated temperature environments.
• Package & Mounting — Radial lead can (φ8 × 20 mm), lead spacing 3.5 mm with ±0.5 mm tolerance; available bulk (no terminal forming) and bag packing for flexible assembly handling.
• Temperature Range — Operates from −55°C to +105°C to cover a wide range of environmental conditions.
• Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low-impedance UPJ series design and strong ripple-current capability make this capacitor suitable for output smoothing and bulk storage in switching regulators.
• General-Purpose Power Filtering — 820 µF capacitance and ±20% tolerance provide reliable decoupling and smoothing on DC rails in a variety of electronic equipment.
• Embedded Power Modules — Compact φ8 × 20 mm can and radial leads simplify PCB layout for space-constrained power modules and converters.

Unique Advantages

• High ripple handling: Specified low- and high-frequency ripple currents (482.4 mA at 120 Hz and 670 mA at 200 kHz) support dynamic load conditions and reduce voltage ripple on power rails.
• Extended endurance at elevated temperature: Rated 3000 hours at +105°C for the φ8 case size, enabling sustained operation in hot environments.
• Compact radial-can form factor: φ8 × 20 mm can with 3.5 mm lead spacing provides a small footprint for dense PCB designs.
• Controlled dissipation: Measured tanδ of 0.22 at 6.3 V (20°C, 120 Hz) indicates controlled loss characteristics for power applications.
• Predictable leakage performance: Specified leakage current (154.98 µA) supports accurate power-budgeting and standby-loss calculations.
• Regulatory compliance: RoHS compliant for use in designs targeting restricted-substance requirements.
