Key Features

• Capacitance & Voltage: 150 µF rated capacitance at 350 V for bulk energy and filtering in high-voltage power stages.
• Snap-in Mounting: Radial, can-type snap-in terminals for secure board retention and straightforward installation in power assemblies.
• High-speed Charge–Discharge: Designed for high speed charge–discharge behaviour suitable for regenerative and pulsed applications.
• Operating Temperature & Endurance: Rated for −25°C to +105°C with an endurance specification of 3000 hours at 105°C under rated bias and ripple conditions.
• High Ripple Capability: Rated ripple currents include 820 mA at 120 Hz and 1.173 A at 50 kHz, supporting both low- and high-frequency ripple environments.
• Cycle Endurance: Series-level qualification includes charge–discharge endurance testing (50 million cycles at specified test conditions) demonstrating stability under repeated cycling.
• RoHS Compliant: Meets the RoHS directive (2011/65/EU, (EU)2015/863) for reduced hazardous substance content.

Typical Applications

• AC Servomotor Regenerative Circuits: Supports high-frequency regenerative voltage handling in servo drives and motion-control systems.
• General Inverters: Suitable for inverter DC-link and filtering duties where high-voltage, high-temperature performance is required.
• Voltage-Doubler Rectifier Circuits: Designed to perform reliably as part of rectifier and voltage-doubler topologies.
• Equipment in Fluctuating-Voltage Areas: Built to tolerate environments with variable supply conditions and transient loads.

Unique Advantages

• High-voltage capability: 350 V rating enables use in higher-voltage power systems without compromising capacitance.
• Designed for rapid charge–discharge: Series intent and testing focus on high-speed cycling make it appropriate for regenerative and pulsed-power applications.
• Elevated temperature endurance: Operation to 105°C with a 3000-hour endurance at that temperature supports extended life in hot power electronics enclosures.
• Measured ripple performance: Specified ripple currents at 120 Hz and 50 kHz provide predictable thermal and electrical behavior across common frequencies.
• Robust cycle stability: Endurance testing (50 million cycles under defined conditions) indicates stable capacitance, tan δ and leakage after repeated charge–discharge events.
• Regulatory compliance: RoHS conformity supports environmental and materials compliance requirements.
