UPJ1J821MHD6

The UPJ1J821MHD6 is a Nichicon UPJ series aluminum electrolytic capacitor in a radial-lead can optimized for power applications. It provides 820 µF capacitance at a 63 V rating with ±20% tolerance, and is specifically positioned for use in switching power supplies and general-purpose electronic power circuits.

Designed for durable, continuous operation, this part delivers specified endurance at elevated temperature and measurable ripple-handling capability, making it suitable for through-hole power assemblies requiring reliable bulk capacitance.

Key Features

• Electrical Performance — 820 µF capacitance at 63 V rated voltage with ±20% tolerance, polarization indicated for correct circuit placement.
• Low Loss (tan δ) — tanδ 0.08 (measured at 20°C, 120 Hz) for the 63 V rating, supporting stable AC performance under rated conditions.
• Ripple Current Capability — Low-frequency ripple current 1.282 A at 120 Hz and high-frequency ripple current 1.78 A at 200 kHz, suitable for power-conversion environments.
• Leakage Current — Specified leakage current of 1,549.8 µA after rated voltage application (1 minute, 20°C), enabling predictable power-loss budgeting.
• Endurance and Reliability — Rated life of 5,000 hours at +105°C under load (per UPJ series endurance specification), demonstrating sustained performance in elevated-temperature applications.
• Package and Mounting — Radial lead can package with 7.5 mm lead spacing (±0.5 mm) and overall size φ18 × 30.5 mm, for through-hole PCB assembly and bulk or bag packing options.
• Operating Range and Compliance — Operating temperature range −55°C to +105°C; RoHS compliant.

Typical Applications

• Switching Power Supplies — Specifically noted for suitability in switching power supplies where low impedance and endurance are required.
• General-Purpose Electronic Equipment — Provides bulk capacitance for general-purpose power sections and energy storage in commercial and industrial electronics.
• Through-Hole Power Assemblies — Radial lead can form factor and 7.5 mm lead spacing make this part appropriate for through-hole power modules and PCB layouts that use radial components.

Unique Advantages

• Low-impedance design for power conversion: The UPJ series is characterized for low impedance and is specified for switching supply use, supporting stable voltage behavior under dynamic loads.
• High ripple-handling capability: Rated ripple currents at both 120 Hz and 200 kHz (1.282 A and 1.78 A respectively) help dissipate AC ripple across a range of power frequencies.
• Extended high-temperature endurance: 5,000 hours rated life at +105°C provides predictable long-term performance for designs operating at elevated temperatures.
• Compact radial can package: φ18 × 30.5 mm size with 7.5 mm lead spacing offers a balance of capacitance and board-level compatibility for through-hole designs.
• Measured loss and leakage specifications: Specified tanδ (0.08 at 20°C, 120 Hz) and explicit leakage current value (1,549.8 µA) simplify electrical modeling and thermal budgeting in designs.
• RoHS compliant: Conforms to RoHS requirements for environmental and regulatory considerations.
