UFW0J333MRD

The UFW0J333MRD is a radial lead aluminum electrolytic capacitor from Nichicon's UFW series, designed for audio equipment applications. It delivers large bulk capacitance in a compact radial can, making it suitable for power supply smoothing and energy storage in audio circuits.

Key attributes include 33 mF (33,000 µF) capacitance at 6.3 V, specified loss tangent (tan δ) at audio-relevant measurement conditions, and rated endurance at elevated temperature—providing a clear specification set for engineers designing audio power stages and related systems.

Key Features

• High Capacitance — 33 mF (33,000 µF) nominal capacitance with ±20% tolerance, offering substantial energy storage for low-frequency smoothing and decoupling in audio power supplies.
• Low-Voltage Rating — Rated at 6.3 V, suitable for low-voltage audio rails and power domains where large capacitance at modest voltage is required.
• Measured Loss Angle (tan δ) — tan δ of 0.10 measured at 20°C and 120 Hz, specified for predictable AC loss behavior in audio-frequency environments.
• Ripple Current Performance — Low-frequency ripple current of 3.9 A at 120 Hz and high-frequency ripple current of 4.485 A at 10 kHz, enabling handling of continuous and high-frequency ripple components common in audio supplies.
• Leakage Current — Specified leakage current of 6,237 µA, derived from rated capacitance and voltage conditions; useful for system-level power-loss budgeting.
• Endurance and Temperature Range — Rated for 2,000 hours at 85°C with operating range from −40°C to +85°C, supporting typical environmental conditions for consumer and professional audio equipment.
• Radial Can Package — φ22 × 50 mm can with 10 mm lead spacing (±0.5 mm) and radial lead configuration for through-hole mounting and straightforward PCB layout.
• Packaging Options — Supplied in Bulk (no terminal forming) or Bag packing to support different assembly and procurement workflows.

Typical Applications

• Audio Power Amplifiers — Bulk storage and supply smoothing for amplifier rails to support transient demand and reduce audible noise.
• Audio Power Supplies — Filtering and energy buffering in low-voltage audio power modules and linear/regulator outputs.
• Mixing Consoles and Signal Processing — Local decoupling and bulk capacitance for board-level audio electronics where stable low-frequency energy reserve is required.

Unique Advantages

• Substantial Energy Storage: 33 mF nominal capacitance provides significant bulk charge capacity to stabilize low-voltage audio rails and support transient loads.
• Tuned for Audio Frequencies: tan δ specified at 120 Hz and ripple current ratings at both 120 Hz and 10 kHz give clear guidance for audio-frequency design trade-offs.
• Robust Thermal Endurance: 2,000-hour rating at 85°C and a −40°C to +85°C operating range offer predictable lifetime behavior in typical audio equipment environments.
• Through-Hole, Serviceable Form Factor: Radial can with 10 mm lead spacing facilitates manual assembly, replacement, and prototyping in professional audio hardware.
• Packaging Flexibility: Available in Bulk or Bag packing to match production or prototyping needs without additional handling complexity.
