UKA1A332MHD

The UKA1A332MHD is a Nichicon UKA series miniature aluminum electrolytic capacitor designed for high-grade audio equipment. It is a polarized, radial-lead can delivering 3.3 mF (3300 µF) at 10 V in a compact φ12.5 × 25 mm package.

Engineered for applications that require high capacitance, wide operating temperature, and sustained endurance, this part provides high ripple-current handling and long life performance for audio power and signal support circuits.

Key Features

• High Capacitance Density — 3300 µF (3.3 mF) provides substantial energy storage and filtering in a compact radial can (φ12.5 × 25 mm).
• Rated Voltage — 10 V rated voltage suitable for low-voltage audio power rails and supply smoothing.
• Wide Temperature Range — Operates from −55 °C to 105 °C, supporting demanding thermal environments.
• Endurance — 2000 hours at 105 °C, providing predictable long-term performance in elevated-temperature conditions.
• Ripple Current Capability — Low-frequency ripple current 1.05 A (120 Hz) and high-frequency ripple current 1.208 A (10 kHz), enabling effective suppression of supply ripple across audio-relevant frequencies.
• Loss Characteristics — Dissipation factor (tan δ) of 0.3 measured at 20 °C, 120 Hz, for predictable ESR-related behavior in audio circuits.
• Mechanical and Mounting — Radial lead mounting with 5 mm lead spacing (±0.5 mm) for through-hole PCB designs; available in Bulk (no terminal forming) or Bag packing.
• Qualification — AEC-Q200 listed in specifications for applications requiring that qualification.

Typical Applications

• Audio Power Supply Smoothing — Bulk decoupling and reservoir capacitance for amplifier and preamplifier power rails.
• Audio Circuit Decoupling — Local supply decoupling in high-grade audio equipment to reduce ripple and support transient currents.
• Compact Equipment Designs — High capacitance in a small φ12.5 × 25 mm can for space-constrained consumer or professional audio products.

Unique Advantages

• High energy storage in a small package: 3300 µF in a φ12.5 × 25 mm can reduces board space while providing significant capacitance for audio power stages.
• Robust thermal endurance: 2000 hours at 105 °C supports designs that experience sustained elevated temperatures.
• Broad operating range: −55 °C to 105 °C enables use across a wide set of environmental conditions.
• Designed for audio performance: Specified tan δ and ripple-current values measured at audio-relevant frequencies help designers predict behavior in audio power and filtering circuits.
• Through-hole radial form factor: 5 mm lead spacing and standard radial can packaging simplify assembly and replacement in serviceable equipment.
• Production-ready availability: Mass production status and established Nichicon UKA series support consistent supply for production programs.
