UKT1A332MHD

The UKT1A332MHD is a miniature aluminum electrolytic capacitor from Nichicon’s UKT series, designed for general audio equipment. This radial-lead, polarized can delivers 3.3 mF (3300 µF) capacitance at a 10 V rating in a compact φ12.5 × 25 mm package.

Engineered for reliability in audio power circuits, the part combines high ripple-current capability, wide operating temperature range, and a 1000-hour endurance rating at 105°C—making it suitable where stable power filtering and long-term thermal resilience are required.

Key Features

• Capacitance & Voltage: 3.3 mF (3300 µF) rated at 10 V, with capacitance tolerance of -20% to +20% for predictable filtering performance.
• Low-frequency and High-frequency Ripple Handling: Low-frequency ripple current 1.05 A at 120 Hz and high-frequency ripple current 1.208 A at 10 kHz, supporting demanding audio power rails.
• Dissipation Factor (tan δ): DF (tan δ) = 0.3 measured at 20°C, 120 Hz, 10 V, enabling designers to assess ESR-related losses precisely.
• Leakage & Endurance: Leakage current specified at 990 µA and rated for 1000 hours at 105°C, with post-test limits for capacitance and leakage per the series endurance specification.
• Wide Temperature Range: Operates from -55°C to +105°C to accommodate varied environmental conditions in audio equipment.
• Package & Mounting: Radial can package, dimension φ12.5 × 25 mm, lead spacing 5 mm (±0.5 mm), supplied in bulk (no terminal forming) or bag packing.
• Compliance & Qualification: RoHS compliant and AEC-Q200 qualified, reflecting manufacturing and quality processes suitable for demanding electronic designs.

Typical Applications

• Audio Equipment: Designed for general audio devices where large capacitance and robust ripple-current capability are required for power supply smoothing and decoupling.
• Power Rail Filtering: Compact radial can enables placement on power rails in amplifier and preamplifier modules to stabilize supply voltages under dynamic load.
• Industrial Audio Systems: Wide -55°C to +105°C range supports use in systems exposed to broad temperature swings while maintaining endurance over time.

Unique Advantages

• High ripple-current capacity: 1.05 A (120 Hz) and 1.208 A (10 kHz) ratings reduce thermal stress on the capacitor during heavy audio duty cycles.
• Compact, service-friendly package: φ12.5 × 25 mm radial can with 5 mm lead spacing provides a small footprint and straightforward through-hole assembly.
• Thermal endurance: Rated for 1000 hours at 105°C, offering predictable aging behavior and stable performance in elevated-temperature applications.
• Measured dissipation factor: Specified tan δ at defined conditions (20°C, 120 Hz, 10 V) helps engineers estimate ESR-related losses accurately during design.
• Standards and compliance: RoHS compliance and AEC-Q200 qualification support regulatory and reliability objectives in product development.
