• High-Temperature Endurance — Specified operating temperature range of −25°C to +105°C with a load life of 5,000 hours at 105°C when subjected to rated ripple current.
• Capacitance Tolerance — ±20% tolerance (120 Hz, 20°C), delivering predictable energy storage within defined limits.
• Polarized Construction — Polarized aluminum electrolytic design for DC applications requiring large capacitance.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements.
• Package Dimensions — Large-format radial can with dimensions reported as L: 19 × D: 9 cm and a seated-height specification provided for mechanical planning.
• Endurance Specifications — After 5,000 hours at 105°C under rated ripple, capacitance change is within ±20% and leakage and tan δ remain within defined limits per the datasheet.

Typical Applications

• Power Supplies — Bulk energy storage and smoothing for high-voltage power supplies, leveraging 12,000 µF at 350 V to stabilize DC rails.
• Industrial Power Conversion — DC-link and filter capacitor in inverters and converters where high ripple current capability and screw-terminal reliability are required.
• Energy Storage in Electronic Equipment — Provides bulk capacitance for load transients and energy buffering in general-purpose industrial equipment.
• High-Voltage Filtering — Filtering and decoupling in systems operating up to the 350 V rating while maintaining performance at elevated temperatures.

Unique Advantages

• High voltage and large capacitance: 350 V rating combined with 12,000 µF enables significant energy density for DC-link and bulk storage roles.
• Robust ripple-current handling: 36 A at 120 Hz and 50.4 A at 100 kHz reduce heating and improve stability in high-disturbance environments.
• Long high-temperature life: Load life of 5,000 hours at +105°C supports reliable operation in hot enclosures and industrial settings.
• Secure screw-terminal connections: Radial can with screw terminals simplifies high-current wiring and mechanical retention in power assemblies.
• Predictable electrical tolerance and endurance: ±20% capacitance tolerance and defined end-of-life limits for capacitance, tan δ, and leakage current help ensure predictable maintenance intervals.
• Regulatory compliance: RoHS conformity supports deployment in regulated markets and product builds.
