Key Features

• Capacitance & Voltage — 150 µF rated capacitance at 400 V suitable for high‑voltage filtering and energy storage tasks.
• High Temperature Endurance — Rated for operation from −25 °C to +105 °C with a guaranteed lifetime of 2000 hours at 105 °C under rated ripple and D.C. bias, maintaining capacitance within ±20% after endurance testing.
• High Ripple Current Performance — Rated ripple current of 880 mA at 120 Hz and 1.012 A at 10 kHz, with provided frequency coefficients to size ripple capability across 50 Hz–10 kHz bands.
• Improved Safety for Abnormal Voltage — Designed with pressure relief vent and enhanced safety features to mitigate abnormal excessive voltage conditions.
• Compact Snap‑in Package — Radial, snap‑in can (φ30 × 25 mm) for secure board mounting and space‑efficient layouts; tray packed for production handling.
• Polarized, General‑Purpose — Polarized construction with ±20% capacitance tolerance for general electronic and power applications.
• RoHS Compliant — Meets RoHS directive requirements, supporting environmental and regulatory considerations.

Typical Applications

• Industrial Power Supplies — Bulk filtering and smoothing in high‑voltage power supplies where 400 V rating and high ripple handling are required.
• Inverters and UPS Systems — Energy storage and ripple attenuation in conversion stages exposed to fluctuating line conditions and elevated temperatures.
• Power Conversion Modules — DC link and filtering duties in converters and rectifier assemblies benefiting from the part’s high ripple current capability and 105 °C endurance.
• Motor Drives and Power Controllers — Support for DC bus stabilization and transient absorption in systems that operate at elevated temperatures and variable voltages.

Unique Advantages

• High‑voltage capability: 400 V rating enables use in a broad range of power electronics where elevated DC voltage handling is necessary.
• Designed for elevated operating temperatures: 105 °C permissible abnormal voltage and a 2000‑hour endurance rating provide confidence in thermal stress environments.
• Robust ripple performance: Specified ripple currents at 120 Hz and 10 kHz plus frequency coefficients allow precise thermal and ripple budgeting for design.
• Safety‑focused construction: Pressure relief vent and improved abnormal voltage tolerance reduce risk under fault or fluctuating voltage conditions.
• Production‑ready packaging: Tray packing supports automated handling and throughput for volume assembly environments.
• Compact physical footprint: φ30 × 25 mm snap‑in can saves board space while providing sturdy mechanical mounting.
