Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for stable electrical characteristics and predictable behavior over temperature.
• Low ESR — 49 mΩ ESR measured at 20°C/100 kHz, suitable for applications where low series resistance is required.
• High Ripple Handling — Rated ripple current of 190 mA at 120 Hz and 1.9 A at 300 kHz, enabling use with both low- and high-frequency switching environments.
• Temperature & Endurance — Operating range −55°C to +105°C with an endurance rating of 2000 hours at 105°C and rated voltage.
• Compact Radial Package — Can-style radial package sized φ6.3 × 7 mm with 2.5 mm lead spacing (±0.5 mm) for through-hole mounting.
• Leakage Current — Specified leakage current of 50 µA after 2 minutes at 25°C.

Typical Applications

• General-purpose circuits — Provides bulk capacitance and smoothing for a wide range of electronic designs that specify general-purpose electrolytic capacitors.
• High-frequency power rails — 1.9 A ripple rating at 300 kHz and 49 mΩ ESR make it suitable where high-frequency ripple attenuation is required.
• Space-constrained assemblies — φ6.3 × 7 mm radial can with 2.5 mm lead spacing fits compact through-hole layouts.

Unique Advantages

• Balanced electrical performance: Combines 33 µF capacitance with low ESR (49 mΩ) to support both capacitance and conduction needs without multiple parallel parts.
