• Audio‑oriented Materials — Selected materials for superior acoustic sound suitable for audio equipment applications.
• Snap‑In Radial Can Package — Snap-in terminal mounting simplifies PCB installation and mechanical retention for power-electronics assemblies.
• Operating Temperature and Endurance — Rated for −25°C to +105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability — Specified ripple current performance of 950 mA at 120 Hz and 1.359 A at 50 kHz, useful for smoothing and decoupling in switching supplies.
• Polarized, General‑Purpose Use — Polarized device intended for general-purpose applications requiring bulk capacitance at high voltage.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU,(EU)2015/863).
• Compact Form Factor — Physical size L: 3.5 × D: 2.5 cm with seated height up to 1.378 inch to fit constrained power boards.

Typical Applications

• Audio Equipment — Bulk energy storage and smoothing where material selection contributes to improved acoustic performance.
• Switching Power Supplies — High-voltage filtering and output smoothing in AC–DC and DC–DC converters for reliable power delivery.
• High‑Voltage Power Electronics — General-purpose decoupling and energy buffering in systems that require 400 V rated capacitance.

Unique Advantages

• High‑Voltage Capability: 400 V rating enables use in 400–450 V rails and high-voltage power stages without overrating the capacitance selection.
• Audio‑Focused Material Selection: Materials chosen to support superior acoustic sound make this part suitable for audio signal and power paths where sonic performance matters.
• Temperature and Endurance: −25°C to +105°C operating range and 2000 hours endurance at 105°C provide predictable performance under elevated temperature stress.
• Frequency‑Aware Ripple Rating: Specified ripple currents at both low (120 Hz) and high (50 kHz) frequencies help designers size capacitors for switching converters and audio power stages.
• Robust Mounting: Snap-in radial can package delivers firm PCB retention and straightforward assembly for production environments.
• Regulatory Compliance: RoHS compliance supports deployment in markets requiring restricted-substance conformity.
