UKL2A3R3MDD

The UKL2A3R3MDD is a radial-lead aluminum electrolytic capacitor designed for low leakage applications. It delivers a 3.3 µF capacitance at a 100 V rating in a compact φ5 × 11 mm can, targeted for audio circuits and other electronics requiring low self-discharge and stable performance.

Key value comes from its low leakage current and controlled dissipation (tanδ), combined with defined ripple current capability and a standardized radial package for through-hole assemblies.

Key Features

• Capacitance and Tolerance — 3.3 µF nominal capacitance with ±20% tolerance, specified at 20°C and 120 Hz.
• High Rated Voltage — 100 V rated voltage suitable for higher-voltage audio and electronic circuits.
• Low Leakage Current — Leakage current of 0.66 µA (measured condition as provided), minimizing self-discharge and bias drift in circuits.
• Low Dissipation Factor — tanδ = 0.07 at 20°C, 120 Hz, supporting efficient energy handling and lower dielectric losses.
• Ripple Current Capability — Specified low-frequency ripple current of 45 mA at 120 Hz and 90 mA at 10 kHz for handling both LF and HF ripple components.
• Endurance — Rated life of 2000 hours at 85°C with the rated voltage applied.
• Package and Mounting — Radial lead can (φ5 × 11 mm) with 2 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Operating Temperature Range — −40°C to +85°C for standard operation.
• RoHS Compliant — Meets applicable RoHS directive requirements.

Typical Applications

• Audio systems — Suited for audio circuitry where low leakage and stable capacitance at up to 100 V are required.

Unique Advantages

• Low self-discharge: The 0.66 µA leakage current reduces bias drift and maintains circuit stability over time.
• High-voltage handling: 100 V rating enables use in higher-voltage audio and electronic designs without up-rating components.
• Compact radial package: φ5 × 11 mm can with 2 mm lead spacing fits space-constrained through-hole layouts while keeping assembly straightforward.
• Measurable loss performance: tanδ = 0.07 at 120 Hz supports predictable dielectric loss characteristics in AC and ripple conditions.
• Dual-frequency ripple spec: Defined ripple current values at 120 Hz and 10 kHz help assess performance across common LF and HF stress conditions.
• Documented endurance: 2000 hours at 85°C provides a clear expectation of long-term performance under elevated temperature stress.
