Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a 400 V rated voltage with ±20% tolerance (120 Hz, 20°C), providing bulk energy storage for power circuits.
• High‑Temperature Operation — Rated for operation from −25°C to +105°C, supporting elevated ambient temperatures common in power conversion equipment.
• High‑speed Charge–Discharge Design — Specified as a 105°C high‑speed charge–discharge snap‑in type, suitable for repeated charge–discharge cycles in regenerative and inverter applications.
• Ripple Current Capability — Rated ripple currents of 1.22 A at 120 Hz and 1.745 A at 50 kHz, enabling effective handling of both low‑ and high‑frequency ripple in power supplies and inverters.
• Endurance & Reliability — Endurance specified as 3000 hours at 105°C under DC bias plus rated ripple current; charge–discharge endurance verified for 50 million cycles under specified conditions.
• Mounting & Package — Snap‑in terminal, radial can construction for robust board mounting in power assemblies; compact footprint with dimensions L: 2.5 × D: 3.5 cm.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC servomotor drives — Used in regenerative circuits to absorb and release energy during frequent braking and acceleration cycles.
• Inverter power stages — Bulk energy storage and ripple filtering in general inverter topologies for industrial drives and power conversion.
• Voltage‑doubler rectifiers — Suited for rectifier circuits where voltage fluctuation and high‑frequency components are present.
• Equipment in fluctuating‑voltage environments — Stabilizes DC links and mitigates transient events in systems subject to variable line conditions.

Unique Advantages

• Designed for frequent charge–discharge — Endurance testing for 50 million charge–discharge cycles (specified conditions) supports use in regenerative and high‑cycle applications.
• High‑temperature durability — 3000‑hour endurance at 105°C under rated conditions provides predictable long‑term performance in hot operating environments.
• Wide ripple‑handling range — Specified ripple current performance at both 120 Hz and 50 kHz accommodates a broad set of power‑electronics switching frequencies.
• Robust snap‑in packaging — Radial, snap‑in can simplifies mechanical mounting and connection in power assemblies while maintaining a compact footprint.
• Regulatory compliance — RoHS conformity supports deployment in designs targeting restricted‑substance compliance requirements.
