UPJ1J820MPD

The UPJ1J820MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series. It is a low-impedance, radial-lead polarized capacitor specified at 82 µF and 63 V, designed for general-purpose use and particularly suited to switching power supply applications.

Key electrical characteristics include a low loss tangent (tanδ) at rated voltage, defined ripple-current ratings at both low and high frequencies, and endurance specified for elevated operating temperature, making it appropriate for power-filtering and decoupling roles in compact assemblies.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with rated voltage of 63 V and capacitance tolerance of -20% to 20%.
• Low Loss Tangent — tanδ = 0.08 measured at 20 °C, 120 Hz and 63 V, supporting lower AC dissipation in power applications.
• Ripple Current Performance — Low-frequency ripple current 200.2 mA (120 Hz) and high-frequency ripple current 385 mA (200 kHz) for filtering across a wide frequency range.
• Leakage Current — Specified leakage current of 154.98 µA, supporting predictable bias behavior in DC circuits.
• Temperature & Endurance — Rated operating range -55 °C to 105 °C with an endurance of 3000 hours at 105 °C for the φ8 case size.
• Compact Radial Package — φ8 × 20 mm can with radial leads, lead spacing 3.5 mm (tolerance ±0.5 mm), suitable for through-hole assemblies and compact power modules.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to support production and prototyping workflows.
• Environmental Compliance — RoHS‑compliant per product data.

Typical Applications

• Switching Power Supplies — Low impedance and defined ripple-current ratings make this part suitable for output filtering and smoothing in switch-mode power supplies.
• General-Purpose Power Filtering — Use for decoupling and bulk storage on DC rails where a compact radial electrolytic is required.
• Embedded and Industrial Electronics — Compact φ8 × 20 mm size and wide temperature range allow use in constrained PCB layouts subjected to elevated temperatures.

Unique Advantages

• Low-impedance performance: Specified tanδ of 0.08 at 63 V and 120 Hz helps reduce AC losses in power-handling locations.
• Defined ripple-current capability: Separate low- and high-frequency ripple ratings (200.2 mA at 120 Hz, 385 mA at 200 kHz) let designers size capacitors for both mains-frequency and high-frequency switching environments.
• Wide operating temperature and proven endurance: -55 °C to 105 °C rating with 3000 hours endurance at 105 °C for the φ8 package supports longevity in thermally demanding applications.
• Compact radial form factor: φ8 × 20 mm can and 3.5 mm lead spacing save PCB space while remaining easy to install in through-hole assemblies.
• Consistent leakage specification: A defined leakage current value of 154.98 µA enables predictable bias design and sizing of bleed or hold circuits.
• RoHS compliance: Meets environmental regulatory requirements for lead‑free assemblies.
