UPJ1E330MDD

The UPJ1E330MDD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series in a radial-lead package. It delivers 33 µF capacitance at a 25 V rating and is designed as a low-impedance, high-reliability type suitable for power filtering and decoupling in compact assemblies.

Key performance attributes include a wide operating temperature range of -55°C to 105°C, explicit ripple current ratings for low- and high-frequency environments, and RoHS compliance. The part is supplied in bulk or bag packing.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 25 V rated voltage and tolerance of -20% to +20%.
• Low Dissipation Factor — tanδ = 0.14 (measured at 20°C, 120 Hz), supporting lower AC loss in filtering applications.
• Ripple Current Capability — Low-frequency ripple current 44 mA at 120 Hz and high-frequency ripple current 88 mA at 200 kHz, specified for typical power-supply environments.
• Leakage Current — Specified leakage current of 24.75 µA.
• Temperature & Endurance — Operating range -55°C to 105°C with an endurance (load life) of 2000 hours at 105°C.
• Compact Radial Package — Can-style radial package with size φ5 × 11 mm (0.5 × 1.1 cm), lead spacing 2 mm (tolerance ±0.5 mm), suitable for through-hole mounting.
• Polarized — Polarized aluminum electrolytic construction for DC power applications.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) and bag packing.
• Product Status — End Of Life.

Typical Applications

• Switching Power Supplies — Low-impedance design and specified ripple current make it suitable for output filtering and decoupling in switching regulators.
• General Power Filtering — Used for bulk smoothing and local decoupling on 25 V rails where a compact radial electrolytic is required.
• Embedded and Industrial Electronics — Compact φ5 × 11 mm footprint and radial leads enable use in space-constrained through-hole boards for control and power modules.

Unique Advantages

• Compact footprint for tight layouts: φ5 × 11 mm can-style package with 2 mm lead spacing enables dense placement on through-hole boards.
• Specified ripple handling across frequencies: Rated ripple currents at 120 Hz and 200 kHz provide clear guidance for both low- and high-frequency power environments.
• High-temperature endurance: Rated to operate up to 105°C with a defined 2000-hour load-life rating for predictable longevity under elevated temperature stress.
• Measurable dissipation performance: tanδ = 0.14 at 20°C/120 Hz gives a quantified dissipation factor to help assess AC loss and thermal behavior in designs.
• RoHS compliant supply options: Environmentally compliant manufacturing and availability in bulk or bagged packing for production or prototyping needs.
