• Snap-in radial can package: Snap-in terminal mounting simplifies insertion and mechanical retention for chassis and PCB assemblies.
• Extended temperature endurance: Rated for operation from −25°C to 105°C with series endurance of 2000 hours at 105°C under rated ripple conditions.
• Ripple current performance: Rated ripple current of 960 mA at 120 Hz and 1.104 A at 10 kHz for handling AC stress in power circuits.
• Polarized electrolytic construction: Polarized device suitable where electrolytic capacitors are required for bulk filtering and energy buffering.
• RoHS compliant: Conforms to 2011/65/EU and (EU)2015/863 environmental directives.
• Series safety features: Pressure relief vent and improved safety design for abnormally excessive voltage conditions to reduce risk of dangerous outcomes.
• Electrical stability parameters: Leakage current governed by I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ ≤ 0.20 at 120 Hz, 20°C.

Typical Applications

• Industrial power supplies: Bulk smoothing and energy storage for switch-mode power supplies and high-voltage converters operating in fluctuating-voltage environments.
• DC-link capacitors: Energy buffering and ripple filtering for inverters and motor drive front-ends where high-voltage DC stability is required.
• Uninterruptible power supplies (UPS): Bulk capacitance for energy hold-up and transient support in backup power systems.
• Renewable power electronics: Voltage stabilization and ripple suppression in PV inverters and other renewable energy converters exposed to variable input conditions.

Unique Advantages

• Rated for elevated temperature endurance: 2000 hours at 105°C under rated ripple current supports long-term reliability in hot operating environments.
• Designed for voltage fluctuation tolerance: Series-level features and abnormal-voltage safety measures reduce risk in systems with variable line conditions.
• Clear electrical limits: Published leakage current formula and tan δ limit allow straightforward design verification and margining.
• High ripple capability: Specified ripple currents at both low and high frequencies help match the part to real-world converter and inverter ripple spectra.
• RoHS-compliant material set: Meets modern environmental requirements for commercial and industrial equipment.
