• Low Impedance: Specified impedance of 47 mΩ for reduced voltage ripple under load.
• Ripple Current Capability: Rated ripple current of 1.322 A at 120 Hz and 1.52 A at 10 kHz to handle AC components in switching supplies.
• Temperature & Endurance: Operating temperature range −40 °C to 105 °C with an endurance specification of 3000 hours at 105 °C.
• Package & Mounting: Radial lead, radial-can package with 7.5 mm lead spacing and compact dimensions (L: 4 × D: 1.8 cm) for through-hole PCB assembly.
• Electrical Tolerance & Polarity: Capacitance tolerance of ±20% and polarized construction for correct orientation in DC circuits.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies: Bulk capacitance and ripple suppression in switching regulator outputs and power rails.
• General-Purpose Power Circuits: Energy storage and filtering in a wide range of through-hole power designs.
• Through-Hole Power Modules: Compact radial-can format simplifies placement in modules that require dependable high-voltage capacitance.
