UKT1A330MDD

The UKT1A330MDD is a miniature, polarized aluminum electrolytic capacitor from Nichicon's UKT series, designed for general audio equipment. It delivers 33 µF capacitance at a 10 V rating in a compact radial-can package with 2 mm lead spacing.

Engineered for reliability in audio applications, the part offers a wide operating temperature range and defined endurance performance, making it suitable for designs that require a small footprint and stable behavior under elevated temperatures.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 10 V rated voltage, suited to low-voltage audio circuits.
• Polarized Design — Radial lead, polarized aluminum electrolytic construction for common audio coupling and filtering configurations.
• Tolerance — Capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20°C) for predictable selection and BOM planning.
• Temperature Range & Endurance — Rated for −55°C to +105°C with a lifetime specification of 1000 hours at 105°C.
• Ripple Current Performance — Specified ripple currents of 58 mA at 120 Hz and 116 mA at 10 kHz to support both low- and high-frequency ripple conditions.
• Package & Mounting — Radial lead, can-style package with compact dimensions L: 1.1 × D: 0.5 cm and 2 mm lead spacing for tight PCB layouts.
• Reliability & Qualification — AEC-Q200 listed rating for designs requiring enhanced component reliability.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Audio Equipment — Intended for general audio equipment use where a polarized aluminum electrolytic capacitor is required in compact circuits.
• Power Decoupling in Audio Circuits — Compact radial-can form factor supports PCB layouts that need local supply smoothing within audio modules.
• Signal Path Support — Suited to applications in audio signal chains that require a 33 µF, 10 V polarized capacitor footprint.

Unique Advantages

• Compact footprint: Small package dimensions (L: 1.1 × D: 0.5 cm) and 2 mm lead spacing enable space-efficient placement in dense audio PCBs.
• Wide operating range: −55°C to +105°C rating provides margin for audio equipment that experiences varied thermal environments.
• Defined endurance: 1000 hours at 105°C gives designers a clear lifecycle expectation for elevated-temperature operation.
• Frequency-aware ripple capability: Specified ripple currents at 120 Hz (58 mA) and 10 kHz (116 mA) help match the part to both low- and high-frequency ripple conditions in audio power stages.
• Industry qualification: AEC-Q200 listing supports use in applications where enhanced component qualification is required.
• Regulatory compliance: RoHS compliance addresses environmental and regulatory considerations for product development.
