• High Voltage Rating — Rated for 400 V DC to support high-voltage power rails and energy buffering.
• High Ripple-Current Performance — Specified ripple current of 17.9 A at 120 Hz and 25.06 A at 100 kHz, enabling effective AC ripple handling and smoothing.
• Thermal and Lifetime Specs — Operating temperature range of −25°C to +105°C and a rated lifetime of 5,000 hours at 105°C.
• Mounting & Package — Screw terminal radial can (radial, can - screw terminals) for secure bolted connections and mechanical robustness.
• Polarized Device — Polarized electrolytic capacitor; designed for correct DC polarity installation.
• Physical Dimensions — Size listed as L: 15 × D: 6.35 cm with a maximum seated height of 5.906 inch, suitable for panel- or chassis-mounted power assemblies.
• RoHS Compliant — Conforms to RoHS directive requirements for lead-free assemblies.

Typical Applications

• General-purpose power filtering — Use where 3.9 mF at 400 V and substantial ripple current capability are needed to smooth DC rails and reduce voltage ripple.
• DC link / energy buffering — Suitable for buffering energy and stabilizing high-voltage DC links where a 400 V rating and 105°C operation are required.
• Industrial power supplies and converters — Screw-terminal mounting and high ripple handling make this capacitor appropriate for robust industrial power assemblies and serviceable installations.

Unique Advantages

• High-voltage energy storage: 400 V rating provides headroom for high-voltage DC systems without stepping up component count.
• Strong ripple-current capability: Specified ripple currents at 120 Hz and 100 kHz help reduce heating and extend service life in AC-pulsed environments.
• Extended high-temperature endurance: Rated for 5,000 hours at 105°C, supporting long-term operation in elevated-temperature enclosures.
• Secure screw-terminal mounting: Radial can with screw terminals facilitates low-impedance connections and mechanically robust installation for field serviceability.
• Clear mechanical footprint: Provided size and seated height data simplify mechanical integration and bracket selection for chassis-mounted designs.
• Regulatory readiness: RoHS compliance supports use in lead-free manufacturing environments.
