• Long-life, High-temperature Design — Rated for 20,000 hours at 105°C under DC bias plus rated ripple current, supporting long operational lifetimes.
• Snap-in Terminal Package — Radial, can-type snap-in mounting for secure PCB attachment and straightforward assembly.
• Operating Range — Specified operating temperature range of −25°C to +105°C for broad thermal use.
• Ripple Current Capability — Rated ripple current of 720 mA at 120 Hz (105°C); frequency coefficient data available for higher frequencies up to 50 kHz (coefficient 1.43 at 50 kHz).
• Electrical Characteristics — Capacitance tolerance ±20%; leakage current defined as I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ ≤ 0.20 at 120 Hz, 20°C.
• Size and Form Factor — Can dimensions 30 mm × 35 mm (φD × L), providing compact high-voltage capacitance in a snap-in can.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• General-purpose power circuitry — Provides high-voltage bulk capacitance for general-purpose circuits requiring polarized electrolytic capacitors.
• High-temperature environments — Suited to applications that require sustained operation up to 105°C and long endurance.
• Board-mounted high-voltage modules — Snap-in terminal type supports secure mounting in assemblies where a radial can configuration is preferred.

Unique Advantages

• High-voltage capability: 450 V rating combined with 120 µF capacitance enables fewer capacitors for a given stored energy requirement.
• Long operational life: Endurance specified as 20,000 hours at 105°C under rated conditions reduces replacement frequency in long-life equipment.
• Robust ripple handling: 720 mA rated ripple at 120 Hz with published frequency coefficients for higher-frequency operation supports varied ripple environments.
• Compact snap-in form factor: 30 × 35 mm can with snap-in terminals simplifies PCB attachment and mechanical stability.
• Measured electrical limits: Clear leakage current and tan δ specifications allow predictable performance validation during design and test.
• RoHS compliance: Meets regulatory requirements for lead-restricted assemblies.
