UKL2A3R3KDD

The UKL2A3R3KDD is a radial‑lead aluminum electrolytic capacitor optimized for low leakage applications. It provides 3.3 µF capacitance at a 100 V rating in a compact φ5×11 mm can, suited for space‑constrained electronics within the audio market and other designs that require small, polarized electrolytic capacitors.

Designed for reliability in elevated ambient conditions, the part offers low leakage, defined ripple current performance across low and high frequencies, and a 2,000‑hour endurance at 85 °C.

Key Features

• Capacitance and Tolerance — 3.3 µF nominal capacitance with ±10% tolerance.
• High DC Voltage — 100 V rated voltage for applications requiring higher voltage margins.
• Low Leakage Current — Specified leakage current of 0.66 µA, supporting circuits where minimal DC leakage is important.
• Ripple Current Performance — Low‑frequency ripple current of 45 mA (120 Hz) and high‑frequency ripple current of 90 mA (10 kHz), enabling stable operation across audio and high‑frequency environments.
• Endurance and Temperature Range — Rated life of 2,000 hours at 85 °C and operating temperature range of −40 °C to 85 °C.
• Package and Mounting — Radial lead can (φ5×11 mm) with 2.0 mm lead spacing (±0.5 mm) for through‑hole assembly; polarization noted.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.
• Environmental Compliance — RoHS‑compliant.

Typical Applications

• Audio — Applicable to audio equipment where a compact, 100 V, low‑leakage electrolytic capacitor is required for coupling, decoupling or biasing tasks.
• Power Supply Filtering — Suitable for small, higher‑voltage filtering roles in power rails where limited ripple currents and low leakage are needed.
• General Purpose Electronics — Useful in space‑constrained through‑hole designs requiring polarized capacitance with defined endurance at elevated temperature.

Unique Advantages

• Low leakage for stable biasing: 0.66 µA leakage current minimizes DC loss and helps preserve circuit bias points over time.
• Compact high‑voltage solution: 100 V rating in a φ5×11 mm package provides high voltage capability without a large footprint.
• Broad frequency ripple handling: Specified ripple currents at 120 Hz and 10 kHz support performance across low and high frequency domains.
• Through‑hole mounting simplicity: Radial leads and standard 2.0 mm lead spacing simplify manual or wave solder assembly and retrofit designs.
• Robust operating range: −40 °C to 85 °C operation with a 2,000‑hour endurance at 85 °C supports sustained use in elevated environments.
• RoHS compliance: Meets environmental requirements for lead‑free systems.
