UKL1C330MDD

The UKL1C330MDD is a low-leakage aluminum electrolytic capacitor in a radial-lead can designed for audio applications. It provides 33 µF capacitance at a 16 V rated voltage with compact dimensions (φ5 × 11 mm) and 2 mm lead spacing.

Key electrical characteristics include low leakage current (1.056 µA), specified ripple current capability at low and high frequency, and 2000 hours endurance at 85°C. Status: End Of Life (scheduled for discontinuation).

Key Features

• Electrical Performance — Capacitance & Voltage 33 µF nominal capacitance with ±20% tolerance and a 16 V rated voltage for low-voltage analog and audio circuitry.
• Low Leakage Current Specified leakage current of 1.056 µA, supporting designs where minimized DC leakage is important.
• Ripple Current Ratings Low-frequency ripple current 100 mA (120 Hz) and high-frequency ripple current 200 mA (10 kHz) for signal- and power-related ripple handling.
• Reliability & Endurance Endurance rated at 2000 hours when operated at 85°C under rated voltage.
• Temperature Range Operating range from −40°C to +85°C to accommodate common ambient conditions for audio equipment.
• Mechanical & Mounting Radial-lead package, polarized construction, size φ5 × 11 mm with 2 mm lead spacing and 0.5 mm lead spacing tolerance for through-hole PCB mounting.
• Packaging & Compliance Available in bulk (no terminal forming) or bag packing. RoHS compliant.

Typical Applications

• Audio Suited for audio circuit use where low leakage and defined ripple current performance contribute to stable decoupling and signal integrity.

Unique Advantages

• Low Leakage A measured leakage current of 1.056 µA reduces DC loss and drift in bias-sensitive audio stages.
• Compact Radial Package φ5 × 11 mm can size with 2 mm lead spacing saves board area while retaining through-hole mounting convenience.
• Frequency-aware Ripple Ratings Defined ripple current values at 120 Hz and 10 kHz enable designers to match capacitor selection to both low- and high-frequency ripple conditions.
• Endurance Specified at Elevated Temperature 2000 hours at 85°C offers a quantified reliability metric for thermal and lifetime planning.
• RoHS Compliant Meets RoHS requirements for adherence to regulatory materials restrictions.
• Multiple Packaging Options Bulk and bag packing choices support different assembly and procurement workflows.
