• Ripple Current Capability Low-frequency ripple current of 1.7 A (120 Hz) and high-frequency ripple current of 1.955 A (100 kHz) to support demanding AC ripple conditions.
• Loss Characteristics tanδ (DF) = 0.24 measured at 20°C, 120 Hz and rated voltage, enabling predictable dissipation characteristics for thermal and reliability planning.
• Reliability and Endurance Rated for 2000 hours at 85°C (endurance), with specified limits for capacitance change, tanδ and leakage current after endurance testing.
• Temperature Range Operates from –40°C to +85°C, supporting a wide range of ambient conditions for general-purpose electronics.
• Compact Radial Package Miniature radial-lead can (φ12.5 × 25 mm) with 5.0 mm lead spacing (±0.5 mm) for easy through-hole mounting and dense PCB layouts.
• Leakage Current Specified leakage current of 1584 µA for predictable standby and operating behavior after voltage application.
• RoHS Compliant Manufactured to meet RoHS requirements, reflecting compliance with the listed directive.

Typical Applications

• General-power filtering — Provides bulk capacitance and ripple-current handling for general-purpose power supply smoothing and energy storage.
• Decoupling in electronic modules — Compact radial package and high capacitance make it suitable for decoupling and stabilization in compact assemblies.
• General-purpose circuitry — Intended for a wide range of general-purpose electronic designs requiring polarized electrolytic bulk capacitance.

Unique Advantages

• High bulk capacitance in a miniature can — 3300 µF in a φ12.5 × 25 mm case delivers significant energy density for space-constrained designs.
