UKL2A2R2MDD

The UKL2A2R2MDD is a low-leakage aluminum electrolytic capacitor in a compact radial-lead can designed for applications that require a high-voltage rating in a small footprint. It delivers 2.2 µF capacitance at a 100 V rating with low dissipation (tanδ) and engineered ripple performance for audio and precision electronics.

With a temperature range of –40°C to 85°C and a rated endurance of 2000 hours at 85°C, this radial-lead unit is suited to designs that need stable electrical characteristics, low leakage, and straightforward through-hole mounting. The product is RoHS compliant and supplied in bulk or bag packing.

Key Features

• Capacitance & Voltage: 2.2 µF nominal capacitance with a 100 V rated voltage and tolerance of –20% to +20%.
• Low Leakage Current: Specified leakage current of 0.44 µA, minimizing DC loss in biasing and coupling applications.
• Low Dissipation Factor: tanδ of 0.07 measured at 20°C, 120 Hz, supporting low-loss performance in audio-frequency circuits.
• Ripple Performance: Rated ripple currents of 28 mA (120 Hz) and 56 mA (10 kHz) to address both low- and high-frequency ripple conditions.
• Package & Mounting: Radial-lead can, size φ5 × 11 mm (0.5 × 1.1 cm), lead spacing 2.0 mm with ±0.5 mm tolerance, for easy through-hole mounting.
• Environmental & Reliability: Operating temperature –40°C to 85°C, endurance 2000 hours at 85°C, and RoHS compliant.
• Availability Status: Product status: End Of Life. Not recommended for new designs.

Typical Applications

• Audio Electronics: Use in audio signal paths and power rails where low dissipation and low leakage support clean signal transfer and stable biasing.
• Power Supply Ripple Filtering: Filtering and smoothing on higher-voltage rails up to 100 V where compact radial leads are required.
• Precision Analog Circuits: Circuits that benefit from low leakage and low tanδ at 120 Hz for reduced DC drift and lower loss in the audio band.

Unique Advantages

• Low leakage for stable biasing: The specified 0.44 µA leakage current helps preserve DC operating points and reduces quiescent losses in bias-sensitive circuits.
• High-voltage capability in a small package: 100 V rating in a φ5 × 11 mm radial can enables use on compact boards with elevated rail voltages.
• Low dissipation at audio frequencies: tanδ of 0.07 at 120 Hz lowers loss in audio-frequency paths, contributing to cleaner signal handling.
• Designed ripple handling: Specified ripple currents at 120 Hz and 10 kHz support both mains-frequency smoothing and higher-frequency decoupling tasks.
• Through-hole simplicity: Radial-lead construction with 2.0 mm lead spacing simplifies assembly for legacy and serviceable designs.
• Regulatory compliance: RoHS compliant for use in designs targeting regulatory conformity.
