Key Features

• Capacitance & Voltage: 2.2 mF nominal capacitance with an 80 V rated voltage, suitable for mid- to high-voltage DC rail support.
• Long-life High-temperature Endurance: Rated for 5000 hours at 105°C under rated ripple and DC bias, enabling prolonged service life in hot operating environments.
• Snap-in Mounting: Radial, snap-in can package provides secure board retention and mechanical stability for through-hole assemblies.
• Operating Temperature Range: Specified for −40°C to +105°C to cover a wide range of industrial operating conditions.
• Ripple Current Capability: Rated ripple current of 2 A at 120 Hz and 2.3 A at 50 kHz to handle AC ripple in power supply applications.
• Polarized Construction & Tolerance: Polarized device with capacitance tolerance of −20% to +20% at 120 Hz, 20°C for predictable behavior in DC circuits.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for restricted hazardous substances.
• Compact Footprint: Package dimensions L: 4.5 × D: 2.2 cm provide a compact solution for board-level power filtering and energy storage.

Typical Applications

• Industrial Power Supplies: Bulk filtering and energy storage where continuous ripple current and elevated operating temperature endurance are required.
• Ballast Equipment: Designed specifically to support ballast circuits with the robustness to tolerate sustained ripple and heat.
• General Purpose Power Conditioning: DC rail smoothing and decoupling in mid-voltage designs that need polarized electrolytic capacitance with long life.

Unique Advantages

• Proven High-temperature Reliability: 5000-hour endurance at 105°C reduces risk of premature degradation in hot environments.
• High Ripple Handling: Specified ripple current ratings at 120 Hz and 50 kHz help ensure stable performance under AC stress typical in power supplies.
• Secure Snap-in Mount: Radial snap-in terminal provides durable board retention for vibration-prone or high-reliability assemblies.
• Wide Operating Range: −40°C to +105°C rating supports a broad range of industrial temperature conditions without derating the part’s life claim.
• Regulatory Compliance: RoHS compliance supports environmentally restricted designs and simplifies regulatory acceptance.
