UPJ2F3R3MPD

The UPJ2F3R3MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series in a radial‑lead can package. Designed for low impedance performance, this polarized capacitor is intended for general-purpose power applications and is specifically suited for use in switching power supplies.

With a 3.3 µF capacitance at a 315 V rating, compact φ10 × 16 mm dimensions and a wide operating temperature range, the UPJ2F3R3MPD delivers robust endurance and measurable ripple performance for demanding power-electronics designs.

Key Features

• Capacitance & Voltage — 3.3 µF capacitance with a 315 V rated voltage, suitable for high-voltage power circuits that require compact capacitance.
• Low Loss (tan δ) — tanδ (DF) 0.2 measured at 20°C, 120 Hz and 315 V, indicating controlled dissipation for power applications.
• Ripple Current Performance — Low-frequency ripple current of 52 mA (120 Hz) and high-frequency ripple current of 83.2 mA (200 kHz), supporting both line-frequency and switching-frequency ripple handling.
• Leakage Current — Specified leakage current of 141.58 µA, providing predictable standby current behavior in powered systems.
• High Reliability Endurance — Rated for 5000 hours at 105°C, offering extended life under elevated temperature load conditions.
• Package & Mounting — Radial lead, polarized can package (φ10 × 16 mm) with 5 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward assembly.
• Wide Operating Temperature — Operates from −40°C to +105°C for broad environmental tolerance.
• Compliance — RoHS compliant.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Switching Power Supplies — Low impedance characteristics and rated endurance make it suitable for filtering and energy storage in switch‑mode regulators.
• General-Purpose Power Filtering — Compact radial package and 315 V rating provide a small-footprint solution for bulk or decoupling tasks in power circuits.
• Power Conversion Circuits — Supports both low- and high-frequency ripple requirements common in DC–DC converters and power-conditioning stages.

Unique Advantages

• Compact high-voltage solution: 3.3 µF at 315 V in a φ10 × 16 mm can saves board area while delivering high-voltage capability.
• Measurable ripple handling: Specified ripple currents at 120 Hz and 200 kHz let designers quantify thermal and AC stress margins for both line-frequency and switching environments.
• Long endurance at elevated temperature: 5000 hours at 105°C provides predictable lifetime performance under continuous load/high-temperature conditions.
• Predictable leakage and dissipation: Defined leakage current and tanδ data help with biasing, bleed resistor sizing, and thermal budgeting.
• Through-hole robustness: Radial lead mounting and controlled lead spacing simplify assembly and provide mechanical durability in power-electronics boards.
