Overview of UKW0J333MRD – Radial Lead Aluminum Electrolytic Capacitor for Audio
The UKW0J333MRD is a Nichicon UKW series miniature aluminum electrolytic capacitor in a radial‑lead can, optimized for audio and AV equipment. It provides substantial bulk capacitance in a compact package for power supply smoothing and energy reservoir applications.
Key electrical attributes include 33,000 µF capacitance at 6.3 V, high ripple handling capability across low and high frequencies, and a rated endurance of 2000 hours at 85°C. The unit is RoHS compliant and supplied in bulk or bag packing.
Key Features
- High Capacitance: 33,000 µF (33 mF) nominal capacitance ideal for large‑value energy storage and smoothing in audio power supplies.
- Low Voltage Rating: Rated at 6.3 V for low‑voltage audio and AV rail applications where high bulk capacitance is required.
- Ripple Current Capability: Low frequency ripple current 3.9 A (120 Hz) and high frequency ripple current 4.485 A (10 kHz), supporting both mains‑frequency smoothing and higher‑frequency decoupling tasks.
- Electrical Loss and Leakage: Dissipation factor (tan δ) 0.92 measured at 20°C, 120 Hz; leakage current specified at 6,237 µA.
- Package & Mounting: Radial lead, polarized can in a φ22 × 50 mm body with 10 mm lead spacing (±0.5 mm), suited for through‑hole board layouts.
- Operating Environment & Lifetime: Rated operating temperature −40°C to +85°C with an endurance rating of 2000 hours at 85°C.
- Compliance & Packaging: RoHS compliant; available in Bulk (no terminal forming) or Bag packing.
- Lifecycle Status: Product status: End Of Life.
Typical Applications
- Audio Power Supplies: Bulk energy storage and smoothing for amplifier rails and preamplifier circuits to support clean audio playback and transient response.
- AV Equipment: Energy reservoir and decoupling in consumer AV systems where high capacitance at low voltage is required in a compact radial package.
- Filter & Decoupling Networks: Low‑frequency smoothing and higher‑frequency ripple suppression across mixed‑signal audio boards.
Unique Advantages
- Large Capacitance in a Compact Can: 33,000 µF in a φ22 × 50 mm package provides significant energy storage without excessive board footprint.
- Dual‑Frequency Ripple Handling: Specified ripple currents for both 120 Hz and 10 kHz enable reliable performance across mains and high‑frequency switching environments.
- Designed for Audio Use: Part of Nichicon’s UKW series developed for audio/AV equipment, suitable where audio‑grade bulk capacitance is needed.
- Wide Temperature Range and Defined Endurance: −40°C to +85°C rating with 2000 hours endurance at 85°C offers predictable lifetime behavior in typical AV deployments.
- Simple Through‑Hole Integration: Radial lead format with 10 mm lead spacing simplifies layout and assembly for traditional PCB designs.
