UKA1E330MDD

The UKA1E330MDD is an aluminum electrolytic capacitor in a radial can package designed for high-grade audio equipment. It provides 330 µF capacitance at a rated voltage of 25 V with a ±20% tolerance (measured at 120 Hz, 20°C), targeting power-supply smoothing and decoupling duties in audio applications.

Engineered for extended operation across a wide temperature range (−55°C to +105°C) and specified for 2000 hours at 105°C, this part delivers stable performance where elevated temperatures and long lifetimes are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 25 V with ±20% tolerance (120 Hz, 20°C), suitable for bulk filtering and decoupling in audio circuits.
• Wide Temperature Range — Rated for operation from −55°C to +105°C, supporting high-grade audio equipment operating in varied thermal environments.
• High-Temperature Endurance — Specified lifetime of 2000 hours at 105°C; endurance characteristics are retained after the defined test conditions.
• Ripple Current Capability — Handles 68 mA at 120 Hz and 136 mA at 10 kHz, enabling reliable ripple suppression across low and high frequency components of audio power rails.
• Radial Lead, Compact Can — Radial lead mounting with 2 mm lead spacing and compact dimensions (L: 1.1 × D: 0.5 cm) for through-hole PCB placement and straightforward assembly.
• Polarized Construction & Marking — Polarized capacitor with marking printed in black on a pearl blue sleeve for clear polarity identification.
• Quality & Compliance — AEC-Q200 rated and RoHS compliant, aligning with industry quality and environmental requirements.

Typical Applications

• High-Grade Audio Equipment — Used for power-supply smoothing and reservoir capacitance in amplifiers, preamplifiers, and other high-fidelity audio gear.
• Professional Audio Electronics — Suitable for rack-mounted and studio equipment where thermal endurance and consistent filtering are required.
• Audio Power Modules — Employed in local decoupling and ripple suppression on audio power rails to support stable operation of analog stages.

Unique Advantages

• Designed for audio environments: Specified for audio applications and built to provide bulk capacitance and ripple handling where signal integrity matters.
• Wide operating temperature: −55°C to +105°C rating enables deployment in equipment exposed to varied thermal conditions without derating the component prematurely.
• Long high-temperature life: 2000-hour endurance at 105°C supports sustained performance in thermally demanding installations.
• Measured ripple performance: Explicit ripple current ratings at 120 Hz and 10 kHz allow designers to size capacitors against measured ripple loads rather than estimates.
• Clear polarity and compact footprint: Black-on-pearl-blue sleeve marking and compact radial can (L: 1.1 × D: 0.5 cm) simplify PCB layout and assembly checks.
• Compliance and qualification: RoHS compliant and AEC-Q200 rated for designers who require documented component quality and environmental conformance.
