• High-temperature endurance: Rated for continuous operation from −25°C to +105°C (for the 400–450 V category) with an endurance specification of 2000 hours at 105°C under rated conditions.
• Snap-in radial can package: Snap-in mounting type for secure PCB installation and robust mechanical retention in power assemblies.
• Ripple current capability: Specified ripple handling of 870 mA at 120 Hz and 1.244 A at 50 kHz, supporting filtering tasks in switching supplies.
• Audio-optimized materials: Constructed with selected materials aimed at achieving superior acoustic sound for audio applications.
• Polarized device: Designed as a polarized electrolytic capacitor for DC filtering and smoothing in power circuits.
• RoHS compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact footprint: Physical size L: 2.5 × D: 3.5 cm with a seated height max of 2.5 cm, suitable for space-conscious power modules.

Typical Applications

• Audio Equipment: Power supply smoothing and decoupling in audio amplifiers and other sound systems where selected materials support acoustic performance.
• Switching Power Supplies: Bulk and smoothing capacitor for high-voltage switch-mode power supplies, benefiting from specified ripple current ratings.
• General-purpose Power Filtering: Energy storage and ripple attenuation in industrial and commercial power electronics that require a 450 V polarized capacitor.

Unique Advantages

• Audio-focused material selection: Materials chosen to help achieve superior acoustic sound, making the part suited for audio-sensitive designs.
