UPJ1K820MHD6

The UPJ1K820MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized capacitor engineered for low impedance performance in power applications.

With an 82 µF capacitance at 80 V, a wide operating temperature range of -55°C to 105°C, and 5,000 hours endurance at 105°C, this part is intended for general-purpose power filtering and switching power supply use where compact size and long-term stability matter.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance rated for 80 V.
• Low loss / Low impedance — tanδ (DF) of 0.08 measured at 20°C, 120 Hz, 80 V for reduced AC loss in power circuits.
• Ripple handling — Low-frequency ripple current of 141.96 mA at 120 Hz and high-frequency ripple current of 273 mA at 200 kHz.
• Leakage current — Specified leakage current of 196.8 µA at rated conditions.
• High reliability life rating — Endurance rated 5,000 hours at 105°C.
• Temperature tolerance — Wide operating range from -55°C to 105°C for demanding thermal environments.
• Mechanical package — Radial lead, can-type package with φ12.5 × 15 mm body and 5.0 mm lead spacing (±0.5 mm).
• Tolerance & polarity — Capacitance tolerance −20% to +20%; polarized (electrolytic) device.
• Packaging options — Available in bulk (no terminal forming) or bag packing.
• RoHS compliant — Conforms to RoHS directive.

Typical Applications

• Switching Power Supplies — Low impedance and specific UPJ-series design make this capacitor suitable for input/output filtering and bulk decoupling in switching regulators.
• DC/DC Converters — Compact 82 µF, 80 V rating and defined ripple limits support DC/DC stage energy storage and ripple suppression.
• General Power Filtering — Used for smoothing and filtering in industrial control and consumer power circuits where long-term stability is required.

Unique Advantages

• Designed for low impedance — Specified tanδ of 0.08 at 20°C/120 Hz helps reduce AC losses and improve transient response in power circuits.
• Long endurance at elevated temperature — 5,000 hours rated life at 105°C delivers predictable performance over prolonged high-temperature operation.
• Clear ripple and leakage specifications — Published low- and high-frequency ripple currents (141.96 mA and 273 mA) and leakage current (196.8 µA) allow straightforward thermal and reliability margining in designs.
• Compact radial package — φ12.5 × 15 mm body with 5 mm lead spacing provides a space-efficient solution for through-hole assemblies.
• Wide operating temperature — −55°C to 105°C range supports applications across varied ambient conditions.
• RoHS compliance — Meets regulatory requirements for lead-free manufacturing environments.
