• Temperature Range & Endurance: Rated for operation from −25°C to +105°C with an endurance rating of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability: Specified ripple current of 1.78 A at 120 Hz and 2.545 A at 50 kHz to support common power supply ripple conditions.
• Tolerance & Polarization: Capacitance tolerance of −20% to +20% and polarized construction for correct DC application.
• Package & Mounting: Radial, snap-in can package (MountingType: Snap In) for secure board retention and simplified assembly in power modules.
• Acoustic Optimization: Selected materials and series design aimed at delivering superior acoustic sound for audio equipment applications.
• Regulatory Compliance: RoHS compliant to 2011/65/EU and (EU)2015/863 for environmental and materials restrictions.
• Physical Size: SizeDimension: L: 4.5 × D: 3.5 cm, suitable for compact high-voltage power assemblies.

Typical Applications

• Audio Equipment: Bulk filtering and energy storage in audio power supplies where selected materials and series design support improved acoustic performance.
• Switching Power Supplies: High-voltage smoothing and ripple handling on 400–450 V rails in switching supply designs, benefiting from the 450 V rating and specified ripple current limits.
• General Purpose Power Filtering: DC link, smoothing, and decoupling in general-purpose power electronics that require a polarized, snap-in aluminum electrolytic capacitor rated for elevated temperatures.

Unique Advantages

• High-Voltage Capability: 450 V rating enables direct use on higher-voltage rails without series arrangements.
• Thermal Reliability: 105°C rated operation with a 2000-hour endurance at 105°C helps maintain performance in thermally demanding environments.
• Measured Ripple Support: Ripple current specifications at 120 Hz (1.78 A) and 50 kHz (2.545 A) provide clear limits for thermal and lifetime budgeting in power designs.
• Snap-In Mounting: Radial snap-in can package simplifies mechanical assembly and provides secure board retention for power modules and cabinets.
• Audio-Optimized Materials: Materials selection focused on acoustic performance helps reduce audible artifacts when used in audio equipment power sections.
• RoHS Compliance: Conforms to 2011/65/EU and (EU)2015/863 for restricted substances, supporting regulatory requirements for many end products.
