UPJ1K820MPD

The UPJ1K820MPD is an 82 µF, 80 V polarized aluminum electrolytic capacitor in a radial lead can package designed for general-purpose power applications. It combines a compact φ10 × 20 mm can with specifications tailored for switching power supplies and other power-filtering uses.

Key value propositions include a rated temperature range of −55 °C to +105 °C, long endurance (5,000 hours at 105 °C), and defined ripple and leakage characteristics for robust performance under DC bias and ripple conditions.

Key Features

• Electrical characteristics — 82 µF nominal capacitance with capacitance tolerance −20% to +20% (±20%), rated for 80 V DC.
• Loss factor (tan δ) — tan δ 0.08 measured at 20 °C and 120 Hz for the 80 V rating, supporting low-loss operation in power circuits.
• Ripple handling — Low-frequency ripple current 147.68 mA at 120 Hz and high-frequency ripple current 284 mA at 200 kHz, enabling effective smoothing in switching regulator and power-filter stages.
• Leakage current — Specified leakage current of 196.8 µA, suitable for applications requiring predictable standby and bias currents.
• High-temperature endurance — Rated for 5,000 hours at 105 °C, providing extended operational life under elevated temperature and load.
• Mechanical and mounting — Radial lead can with φ10 × 20 mm size, 5.0 mm lead spacing (±0.5 mm), and lead diameter typical for φ10 case, for easy through-hole PCB mounting and mechanical stability.
• Packaging and production — Available in bulk (no terminal forming) or bag packing; product is in mass production and RoHS compliant.

Typical Applications

• Switching power supplies — Provides bulk and smoothing capacitance with low loss and defined ripple performance for DC-DC converters and SMPS output stages.
• Power filtering — Used for decoupling and filtering on higher-voltage rails where an 80 V rating and predictable leakage are required.
• Industrial and consumer equipment — General-purpose power stabilization in instrumentation, control electronics, and other devices operating across −55 °C to +105 °C.

Unique Advantages

• 80 V rating with compact size — Delivers 82 µF capacitance in a φ10 × 20 mm package, enabling higher-voltage designs without a large board footprint.
• Defined low-loss behavior — tan δ of 0.08 at 20 °C/120 Hz supports efficient energy handling and reduced heating in power circuits.
• Measured ripple specs at multiple frequencies — Published ripple current values at 120 Hz and 200 kHz let designers size capacitors against both low- and high-frequency ripple sources.
• Long endurance at elevated temperature — 5,000-hour rating at 105 °C provides predictable lifetime for designs exposed to sustained thermal stress.
• Through-hole radial can format — Simple radial-lead mounting with 5 mm lead spacing and common can dimensions eases PCB layout and assembly for legacy and new designs.
• RoHS compliant and mass-produced — Readily available with environmental compliance for volume production needs.
