UPJ2A3R3MDD

The UPJ2A3R3MDD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series, supplied in a radial-lead can (φ5 × 11 mm). It delivers 3.3 µF capacitance at a rated voltage of 100 V and is intended for general-purpose power applications where compact size and stable performance across a wide temperature range are required.

As a member of the UPJ series, this part benefits from a low-impedance design suited to switching power supplies and other power-filtering roles, while offering a wide operating temperature range and defined ripple and leakage characteristics for predictable behavior in end designs.

Key Features

• Capacitance & Voltage — 3.3 µF rated capacitance with a 100 V nominal rating and tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Low-loss Performance — Tangent of loss angle (tan δ) of 0.08 (measured at 20°C, 120 Hz, at 100 V) for controlled dissipation in power circuits.
• Ripple Current Ratings — Defined ripple capability with 13.5 mA at 120 Hz (low frequency) and 27 mA at 200 kHz (high frequency), supporting decoupling and filtering tasks across frequencies.
• Leakage Current — Specified leakage current of 9.9 µA for predictable standby and quiescent current behavior after voltage application.
• Thermal & Lifetime Characteristics — Operating temperature range of -55°C to +105°C and a specified life/endurance of 2000 hours at elevated conditions for design margining.
• Compact Radial Package — Small footprint (φ5 × 11 mm), radial lead mounting with 2.0 mm lead spacing (±0.5 mm), packaged bulk/bag for flexible assembly handling.
• Environmental Compliance — RoHS compliant to support regulatory requirements for lead-free manufacturing.

Typical Applications

• Switching Power Supplies — Low-impedance characteristics of the UPJ series make this part suitable for output smoothing and decoupling in switch-mode power supplies.
• General-Purpose Power Filtering — Compact radial package and defined ripple/leakage specs support board-level filtering in compact power subsystems.
• Compact Power Modules — Small diameter and short length allow use where board space is constrained while maintaining 100 V capability.

Unique Advantages

• Small form factor with 100 V rating: Enables higher-voltage designs without a large footprint, useful in space-limited boards.
• Measurable low loss (tan δ = 0.08): Predictable dissipation helps designers manage thermal and ripple performance in power circuits.
• Frequency-aware ripple specifications: Separate low- and high-frequency ripple current values provide clarity for design across switching and high-frequency environments.
• Wide temperature range: Rated from -55°C to +105°C for stable performance across common industrial and general-purpose environments.
• Radial lead ease-of-use: Through-hole radial mounting and standard lead spacing simplify prototyping and replacement in legacy or serviceable designs.
• RoHS compliant: Supports lead-free manufacturing requirements and regulatory compliance efforts.
