UVK1C333MRD

The UVK1C333MRD from Nichicon is a miniature, radial-lead aluminum electrolytic capacitor in the UVK series. It provides high bulk capacitance in a compact φ25 × 50 mm can and is offered as a standard radial lead type for general-purpose electronic designs.

Designed for applications that require large capacitance at a 16 V rating, the UVK1C333MRD delivers specified ripple-current capability, a broad operating temperature range, and defined endurance characteristics for predictable lifecycle behavior.

Key Features

• Capacitance & Voltage — 33,000 µF (33 mF) nominal capacitance at a rated voltage of 16 V with capacitance tolerance of -20% to +20%.
• Dissipation Factor (tan δ) — Specified DF (tan δ) value of 0.84 measured at 20°C, 120 Hz under the provided product data.
• Ripple Current Handling — Low-frequency ripple current 4.8 A at 120 Hz and high-frequency ripple current 5.52 A at 10 kHz, enabling robust performance on power rails with AC ripple.
• Leakage Current — Specified leakage current of 15,840 µA as provided in the product description.
• Endurance & Temperature Range — Life rating of 2,000 hours at 85°C and an operating temperature range of -40°C to +85°C.
• Compact Radial Package — φ25 × 50 mm can with radial leads, lead spacing 12.5 mm (±0.5 mm), packaged as Bulk (No Terminal Forming) or Bag Packing.
• Polarized, General-Purpose Type — Polarized aluminum electrolytic capacitor intended for general-purpose electronic applications.
• RoHS Compliance — Compliant with RoHS as noted in the UVK series documentation.

Typical Applications

• General-purpose power filtering — Bulk capacitance for smoothing and energy storage where 16 V rating and high capacitance are required.
• Power-rail bulk storage — Provides bulk energy reserve and ripple damping on DC power rails in general electronic equipment.
• General-purpose electronic circuits — Suitable for designs demanding large capacitance in a compact radial-lead package.

Unique Advantages

• High bulk capacitance in a compact can: 33,000 µF in a φ25 × 50 mm package reduces board area required for large energy-storage needs.
• Robust ripple-current performance: Rated for 4.8 A at 120 Hz and 5.52 A at 10 kHz to support demanding AC ripple conditions on power rails.
• Defined endurance at elevated temperature: 2,000-hour life at 85°C provides predictable aging and performance planning.
• Wide operating temperature: –40°C to +85°C supports deployments across a broad set of environmental conditions.
• Standard radial form factor and packaging options: Radial leads with 12.5 mm spacing (±0.5 mm) and bulk/bag packing simplify assembly and inventory choices.
• RoHS-compliant series: Conforms to RoHS directives as documented for the UVK series.
