• Endurance and Reliability — 5,000-hour load life at 85°C when subjected to rated DC bias plus rated ripple current, meeting endurance criteria after restoration to 20°C.
• Electrical Characteristics — Polarized capacitor with ±20% capacitance tolerance (at 120 Hz, 20°C), tan δ = 0.2 and specified leakage current of 3.74 mA.
• Operating Environment — Specified operating temperature range of -25°C to +85°C and RoHS compliance for environmental compatibility.
• Mechanical Size — φ76.2 × 95L (diameter × length) package; dimensional listing also shown as L: 9.5 cm × D: 7.62 cm for integration planning.

Typical Applications

• General-purpose power systems — Suited where a 3,900 µF, 400 V polarized capacitor with screw-terminal mounting is required for bulk capacitance in power racks and assemblies.
• General-purpose industrial equipment — Applicable in industrial modules and power electronics that require durable screw-terminal connections and multi-kiloamp ripple handling at applicable frequencies.
• General-purpose assemblies — A RoHS-compliant option for systems requiring long-life electrolytic capacitance within -25°C to +85°C operating range.

Unique Advantages

• High-voltage bulk capacitance: 3.9 mF at 400 V provides substantial energy storage in a single component, reducing the number of capacitors required in high-voltage designs.
