UKA1H332MHD

The UKA1H332MHD is a polarized aluminum electrolytic capacitor in a radial, can-style package offering 3300 µF capacitance at 50 V with ±20% tolerance. It is designed for high-grade audio applications and other designs that require substantial bulk capacitance, high ripple handling and a wide operating temperature range.

Key performance highlights include a measured tanδ of 0.18 at 20°C/120 Hz, rated ripple current capabilities at both low and high frequency, and 2000 hours endurance at 105°C—making this capacitor suitable for demanding analog and power filtering roles in through-hole designs.

Key Features

• Capacitance & Voltage: 3300 µF (3.3 mF) rated at 50 V with ±20% tolerance for bulk energy storage and smoothing.
• Low Loss (tanδ): tanδ = 0.18 measured at 20°C and 120 Hz, supporting stable performance in audio and filter circuits.
• High Ripple Current: Supports 1.77 A (1770 mA) at 120 Hz and 2.035 A at 10 kHz, enabling effective power-supply decoupling across frequency ranges.
• Leakage Current: Specified leakage current of 4950 µA for this part number.
• Endurance & Temperature Range: Rated for 2000 hours at 105°C and operational from −55°C to 105°C for wide environmental tolerance.
• Package & Mounting: Radial lead, can package with dimensions φ18 × 35.5 mm and lead spacing 7.5 mm (±0.5 mm), supplied in bulk/bag packing for through-hole assembly.
• Reliability Rating: AEC-Q200 listed in specifications for enhanced component reliability where specified.

Typical Applications

• High-grade audio equipment: Bulk supply smoothing and power-stabilization in audio amplifiers and signal chains where low loss and stable capacitance matter.
• Amplifier power decoupling: Provides local energy reservoir and ripple suppression for power rails in amplifier and preamplifier circuits.
• Studio and consumer audio electronics: Long endurance and wide temperature range support reliable performance in professional and consumer devices.

Unique Advantages

• Large capacitance in a compact radial can: 3300 µF in a φ18 × 35.5 mm package delivers substantial energy storage while fitting standard through-hole layouts.
• Frequency-capable ripple handling: Rated ripple currents at 120 Hz and 10 kHz give designers confidence across both mains-frequency smoothing and higher-frequency decoupling tasks.
• Designed for audio performance: Low tanδ at 120 Hz supports applications that prioritize audio fidelity and low-loss filtering.
• Wide operating temperature and proven endurance: −55°C to 105°C rating and 2000 hours at 105°C endurance help ensure long-term stability in challenging environments.
• Through-hole assembly ready: Radial lead spacing and bulk/bag packing simplify handling and placement for manual or wave-solder assembly processes.
• AEC-Q200 in specifications: Adds a recognized reliability reference for designs that require documented component robustness.
