Key Features

• Capacitance and Voltage — 680 µF nominal capacitance at a rated voltage of 350 V, with a tolerance of ±20% (–20% to +20%).
• High‑Temperature Endurance — Qualified to withstand 3000 hours of rated ripple current at 105°C when used under the specified test conditions.
• Ripple Current Performance — Rated ripple current of 1.7 A at 120 Hz and 2.431 A at 100 kHz, supporting demanding AC ripple workloads within the specified limits.
• Operating Temperature Range — Specified for operation from –25°C to +105°C for this voltage class, enabling use in elevated temperature environments.
• Package and Mounting — Snap‑in radial can package for secure PCB mounting and mechanical stability in through‑hole assemblies.
• Polarized Design — Polarized electrolytic capacitor intended for DC bias applications requiring polarity awareness.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Power Circuits — Provides bulk capacitance and filtering at 350 V nominal for general purpose power supply designs and energy storage on DC rails.
• Industrial Electronics — Suited for industrial equipment requiring high‑temperature endurance and reliable ripple current handling in a snap‑in package.
• Power Conditioning Modules — Useful where sustained ripple current at elevated temperature is required to maintain stable voltage smoothing over long duty cycles.

Unique Advantages

• High Temperature Reliability — Rated to endure 3000 hours of operation at 105°C under rated ripple conditions, supporting long‑term stability in hot environments.
• Compact Snap‑in Packaging — Snap‑in radial can construction offers secure through‑hole mounting and a smaller case footprint relative to some series alternatives.
• Strong Ripple Handling — Specified ripple currents at 120 Hz and 100 kHz enable predictable thermal and electrical performance under AC stress.
• RoHS Compliance — Meets RoHS directive requirements for material compliance in regulated markets.
• Clear Electrical Specification — Well‑defined parameters (680 µF, 350 V, ±20% tolerance, polarized) simplify selection and BOM documentation.
