UPJ1J821MHD

The UPJ1J821MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial‑lead can designed by Nichicon. It provides 820 µF capacitance at a 63 V rating with a compact φ16 × 35.5 mm package and 7.5 mm lead spacing.

Engineered for low impedance and long life (5,000 hours at 105°C), this part is ideally suited for switching power supplies and general‑purpose power applications where sustained ripple handling, wide temperature range, and reliable operation are required.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance with a 63 V rated voltage and tolerance of −20% to +20% for bulk energy storage and decoupling tasks.
• Low Dissipation Factor — tanδ 0.08 measured at 20°C, 120 Hz, indicating low loss under rated conditions.
• High Reliability / Long Life — Endurance specified as 5,000 hours at 105°C under rated voltage and ripple conditions.
• Ripple Current Capability — Handles 1.354 A at 120 Hz (low frequency) and 1.88 A at high frequency (200 kHz), supporting demanding ripple environments found in power converters.
• Leakage Current — Part‑specific leakage current listed as 1,549.8 µA under rated conditions.
• Radial Lead, Compact Can — φ16 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm tolerance) and radial mounting for through‑hole PCB layouts.
• Wide Operating Temperature — Specified for −55°C to +105°C to cover a broad range of operating environments.
• Packaging & Availability — Supplied in bulk (no terminal forming) or bag packing; status: mass production. RoHS compliant.

Typical Applications

• Switching Power Supplies — Ideally suited for use in switching converters where low impedance and ripple handling are required.
• General‑Purpose Electronics — Bulk capacitance and 63 V rating make it suitable for general power filtering and energy storage in a wide range of designs.
• Compact Radial‑Lead Power Assemblies — Radial can format (φ16 × 35.5 mm) with 7.5 mm lead spacing fits common through‑hole power module layouts.

Unique Advantages

• Long Endurance at Elevated Temperature — 5,000 hours at 105°C provides predictable life performance for thermal stress conditions.
• Designed for Low Impedance — Low dissipation factor (tanδ 0.08) and specified ripple currents support stable performance under continuous DC bias and AC ripple.
• High Ripple Handling Across Frequencies — Specified ripple current at both 120 Hz and 200 kHz addresses performance needs from line‑frequency to high‑frequency converter environments.
• Compact, Through‑Hole Form Factor — Radial lead, can‑style package simplifies mounting and replacement in existing through‑hole power designs.
• Manufacturer Backing and Production Readiness — Produced by Nichicon and offered in mass production with standard packing options for volume deployment.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.
