UKL1C332MHD

The UKL1C332MHD is a radial-lead aluminum electrolytic capacitor engineered for low leakage performance. It provides 3300 µF of capacitance at a 16 V rating in a compact φ16 × 35.5 mm can with 7.5 mm lead spacing.

Designed for audio and related electronic applications, this capacitor delivers substantial bulk capacitance, controlled leakage characteristics, and defined ripple-handling capability across low and high frequencies, with an operating temperature range of −40°C to 85°C and a rated endurance of 2000 hours at 85°C.

Key Features

• Capacitance and Voltage  3300 µF nominal capacitance at a 16 V rated voltage with ±20% tolerance, providing substantial bulk energy storage for power rails and decoupling.
• Low Leakage Current  Specified leakage current of 105.6 µA for minimized standby losses and stable bias performance in long-running circuits.
• Ripple Current Capability  Low-frequency ripple current of 1.55 A (120 Hz) and high-frequency ripple current of 1.7825 A (10 kHz), allowing effective handling of both mains-frequency and higher-frequency ripple components.
• Thermal and Endurance  Rated for operation from −40°C to 85°C with a life/endurance rating of 2000 hours at 85°C, supporting sustained operation in moderate-temperature environments.
• Radial Lead, Compact Can  φ16 × 35.5 mm case with 7.5 mm lead spacing (±0.5 mm) and radial leads for through-hole mounting and straightforward PCB integration; available in bulk or bag packing.
• Polarized Electrolytic Type  Polarized aluminum electrolytic construction suitable for DC bus and power-smoothing applications.
• RoHS Compliant  Conforms to RoHS requirements for environmental compliance.

Typical Applications

• Audio power supplies  Provides bulk capacitance and low leakage for power-supply smoothing and reservoir functions in audio amplifiers and preamplifiers.
• Signal and analog circuits  Used where substantial capacitance and controlled leakage help stabilize biasing and decoupling networks in analog stages.
• Power filtering  Suited for filtering and ripple suppression on DC rails where both low- and high-frequency ripple must be managed.

Unique Advantages

• High bulk capacitance: 3300 µF delivers significant energy storage for smoothing and transient support.
• Measured low leakage: 105.6 µA specified leakage helps preserve bias accuracy and reduce standby current draw.
• Dual-frequency ripple handling: Rated ripple currents for 120 Hz and 10 kHz give designers predictable performance across common ripple spectra.
• Robust endurance rating: 2000 hours at 85°C provides a defined lifetime metric for thermal-stressed designs.
• Through-hole simplicity: Radial lead configuration and 7.5 mm lead spacing simplify PCB layout and replacement maintenance.
• Regulatory compliance: RoHS compliance supports environmental and regulatory program requirements.
