UPJ1A821MHD6

The UPJ1A821MHD6 from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in the UPJ series, configured as a radial-lead can. Designed for power applications, it provides 820 µF of capacitance at a 10 V rating with a polarized mounting type and compact φ12.5 × 15L package.

Engineered for demanding power supply and general-purpose filtering use, this part combines series-level low-impedance construction and extended endurance to support stable operation across a wide temperature range from -55°C to +105°C.

Key Features

• Capacitance and Rating — 820 µF nominal capacitance with a rated voltage of 10 V and capacitance tolerance of -20% to +20%.
• Low Impedance Design — Series-level low-impedance construction intended for switching power supply applications, helping to reduce voltage ripple under load.
• High Reliability Endurance — Rated for 5000 hours at +105°C (for applicable case sizes), supporting long-term operation in elevated-temperature environments.
• Loss Tangent (tan δ) — tan δ (DF) of 0.19 measured at 20°C, 120 Hz for the 10 V rating, providing a quantified dissipation characteristic.
• Ripple Current Capability — Low-frequency ripple current of 561.6 mA at 120 Hz and high-frequency ripple current of 780 mA at 200 kHz to support power filtering across frequencies.
• Leakage Current — Specified leakage current of 246 µA, measured after rated voltage application as provided in the product data.
• Compact Radial Package — Φ12.5 mm diameter × 15 mm length can with radial leads and 5 mm lead spacing (±0.5 mm), suitable for through-hole assembly and compact board layouts.
• RoHS Compliant — Meets the listed RoHS directive compliance for environmental requirements.
• Packaging and Availability — Available in bulk (no terminal forming) or bag packing; product is in mass production.

Typical Applications

• Switching Power Supplies — Uses include input/output filtering and bulk decoupling where the series’ low-impedance characteristics help control ripple and stabilize rails.
• General-Purpose Power Filtering — Suitable for a wide range of general-purpose power-supply filtering tasks in industrial and consumer electronics requiring a polarized electrolytic solution.
• Embedded and PCB Power Rails — Compact radial can and 5 mm lead spacing make it appropriate for through-hole power smoothing and energy storage on compact boards.

Unique Advantages

• Extended High-Temperature Life — 5000-hour endurance at +105°C supports designs that demand long-term reliability under thermal stress.
• Measured Dissipation Figure — Specified tan δ (0.19 at 20°C, 120 Hz) gives designers a concrete parameter for loss and heating calculations.
• Frequency-Spanning Ripple Handling — Published ripple current values at both low and high frequencies enable predictable performance for switching and high-frequency power systems.
• Compact, Through-Hole Form Factor — φ12.5 × 15L radial can with standard lead spacing simplifies placement in designs that require robust mechanical mounting and serviceability.
• Clear Manufacturing and Packaging Options — Bulk and bag packing choices support flexible procurement and assembly workflows; part is in mass production for steady supply.
• RoHS Compliance — Environmental compliance assists in meeting regulatory requirements for electronic products.
