UKL1C101MPD

The UKL1C101MPD is a low-leakage aluminum electrolytic capacitor in a radial-lead can designed for compact electronic designs. It provides 100 µF capacitance at a 16 V rating with a polarized radial-lead package and is tailored for audio and related low-frequency applications.

With a small φ8 × 11.5 mm case and 3.5 mm lead spacing, this part combines low leakage, defined ripple-handling capability across low and high frequencies, and a 2000-hour endurance at 85°C for stable performance in temperature-limited environments.

Key Features

• Low Leakage Current — Specified leakage current of 3.2 µA for reduced standby loss and improved bias stability in DC-coupled circuits.
• Capacitance & Voltage — 100 µF nominal capacitance with ±20% tolerance rated at 16 V to support decoupling, coupling and power-supply smoothing tasks.
• Ripple Handling (Low & High Frequency) — Rated ripple current of 230 mA at 120 Hz and 345 mA at 10 kHz, enabling effective filtering across audio and higher-frequency switching environments.
• Compact Radial Package — φ8 × 11.5 mm can with 3.5 mm lead spacing and radial mounting for straightforward PCB assembly and through-hole installations.
• Operating Temperature & Endurance — Specified operating range from −40°C to 85°C with 2000 hours endurance at 85°C for predictable life under rated conditions.
• Compliance & Packaging — RoHS-compliant construction; available in bulk (no terminal forming) or bag packing for volume assembly.

Typical Applications

• Audio circuits — Ideal for power-supply decoupling and signal coupling in audio front-ends and amplifiers where low leakage and stable ripple performance matter.

Unique Advantages

• Low standby loss: The 3.2 µA leakage current minimizes bias drift and power draw in idle states, beneficial for battery- or energy-conscious designs.
• Dual-frequency ripple capability: Rated ripple currents at 120 Hz and 10 kHz let you design for both mains-derived and higher-frequency switching environments with a single part.
• Small footprint: φ8 × 11.5 mm case and 3.5 mm lead spacing save board area while retaining through-hole robustness for manual or wave-solder assembly.
• Thermal endurance: 2000-hour rating at 85°C provides a defined life expectancy for designs operating near the upper end of the specified temperature range.
• Regulatory compliance: RoHS-compliant manufacturing supports environmentally conscious product requirements.
• Simple stocking options: Bulk or bag packing choices accommodate different assembly and inventory workflows.
