Key Features

• High Capacitance: 680000 µF (680 mF) provides substantial bulk energy storage for smoothing and decoupling in power systems.
• Rated Voltage: 25 V nominal rating suitable for low-voltage power rails and DC bus applications.
• Elevated Temperature Endurance: Rated for operation from −40°C to +105°C with a specified load life of 2000 hours at +105°C under rated ripple current for the 10 to 250 V range.
• High Ripple Current Capability: Specified ripple current of 24.2 A at 120 Hz and 27.83 A at 100 kHz, supporting applications with substantial AC or switching ripple.
• Screw Terminal Mounting: Radial can package with screw terminals for secure, low-resistance connections and straightforward panel or bracket mounting.
• Polarized Construction: Polar capacitor type with ±20% capacitance tolerance at 120 Hz, 20°C.
• RoHS Compliant: Conforms to the RoHS directive, supporting regulatory and environmental requirements.
• Physical Size: Large-form factor: length 22 cm × diameter 9 cm (height seated max 8.661 inch), suited for designs that accommodate substantial capacitors.

Typical Applications

• Power Supply Smoothing: Bulk filtering on low-voltage DC rails to reduce ripple and stabilize supply under load transients.
• Energy Storage for Power Electronics: Bulk energy reservoir for inverters, converters, and large switching supplies where high capacitance and ripple tolerance are required.
• Industrial Power Systems: Filtering and decoupling in industrial equipment and control panels that demand durable screw-terminal connections and high-temperature operation.

Unique Advantages

• Massive Bulk Capacitance: 680000 µF provides significant energy storage to support long hold-up times and smoothing on high-current rails.
• Defined High Ripple Ratings: Explicit ripple current specifications at 120 Hz and 100 kHz enable predictable thermal and electrical design margins.
• Robust Mechanical Termination: Screw terminal format delivers secure, low-resistance electrical connections and simplifies mounting with brackets.
• Wide Operating Temperature: −40°C to +105°C rating allows deployment in elevated-temperature environments while maintaining performance.
• Proven Load-Life Specification: 2000 hours at +105°C under rated ripple current (for 10–250 V range) gives a clear reference for endurance planning.
• Regulatory Compliance: RoHS compliance supports environmentally regulated product designs.
