• High Voltage Rating — Rated voltage 400 V; series supports extended voltage options (200 V, 400 V, 420 V).
• Temperature and Endurance — Operating temperature range −25°C to +105°C and specified endurance of 2000 hours at 105°C under rated ripple conditions.
• Ripple Current Performance — Rated ripple current of 1.45 A at 120 Hz and 1.667 A at 10 kHz, supporting steady AC ripple handling.
• Mounting & Package — Snap-in terminal, radial can (snap-in) package for secure board mounting and mechanical stability.
• Safety Features — Improved safety characteristics for abnormally excessive voltage; series safety performance includes a pressure relief vent designed to operate without dangerous conditions.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Polarized Construction — Designed as a polarized electrolytic capacitor for power filtering and energy storage applications.

Typical Applications

• General-purpose power filtering: Bulk smoothing and decoupling in general-purpose electronic equipment using the 470 µF/400 V rating.
• Equipment in voltage-fluctuating areas: Suited for systems exposed to variable line conditions thanks to improved safety features and 105°C permissible abnormal voltage capability.
• High-temperature installations: Applicable where elevated ambient or internal temperatures require components rated to −25°C to +105°C and validated for 2000 hours at 105°C.

Unique Advantages

• Long high-temperature endurance: 2000 hours of rated ripple-current application at 105°C provides predictable performance in elevated-temperature environments.
• High-voltage capability: 400 V rating (with series options to 420 V) enables use in higher-voltage power circuits without changing capacitor family.
• Robust ripple handling: Defined ripple current specifications at both 120 Hz and 10 kHz support stable operation across common power frequencies.
• Snap-in mounting for secure installation: Radial snap-in can package simplifies mechanical retention and PCB assembly for power modules.
• Built-in safety design: Pressure relief vent and improved safety measures reduce the risk of hazardous failure under abnormal over-voltage conditions.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for many designs.
