Key Features

• Capacitance & Voltage — 56 mF capacitance rated at 16 V for bulk energy storage and smoothing in power circuits.
• High Ripple Current Endurance — Rated ripple current: 7.69 A at 120 Hz and 8.844 A at 50 kHz, with endurance under rated ripple current for 3000 hours at 85°C.
• Temperature Range — Operating temperature range from −40°C to +85°C suitable for a wide range of industrial and commercial environments.
• Reliability & Lifetime — Endurance specification: meet performance criteria after D.C. bias plus rated ripple current applied for 3000 hours at 85°C; shelf life specification after 1000 hours at 85°C with subsequent voltage treatment.
• Leakage and Dissipation Characteristics — Leakage current specified as I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ maximum of 0.50 at the 16 V rating (measured at 120 Hz, 20°C).
• Package & Mounting — Snap-in terminal, radial can package for secure board mounting; physical dimensions L: 4.5 × D: 3.5 cm with seated height up to 1.772 inch.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Bulk Storage — Provides high-value capacitance for smoothing and energy buffering in DC power supplies and converters.
• Ripple Current Filtering — Suited for circuits that require sustained ripple-current performance at 120 Hz and higher frequencies up to 50 kHz.
• Industrial Equipment — Used in general-purpose industrial electronics where long endurance at elevated temperature is required.
• General-Purpose Electronics — Applicable wherever polarized bulk capacitance and snap-in mounting are preferred for reliable board-level installation.

Unique Advantages

• High Bulk Capacitance: 56 mF provides substantial energy storage in a single component, reducing the need for multiple parallel devices.
• Sustained High Ripple Capability: Specified ripple currents at both low and high frequencies with 3000-hour endurance at 85°C enable reliable operation under continuous load conditions.
• Robust Temperature Performance: −40°C to +85°C operating range and defined endurance at 85°C support deployment in demanding environments.
• Predictable Leakage Behavior: Leakage current defined by I ≤ 3√CV (μA) allows designers to account for self-discharge and bias behavior in precision power designs.
• Snap-In Mounting: Radial snap-in can improves mechanical retention and simplifies assembly for board-level power modules.
• RoHS Compliant: Conforms to current RoHS directive requirements for environmental compliance.
