Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 35 V provides bulk energy storage for power rails and smoothing in converters.
• Low Impedance — Specified impedance of 70 mOhm supports effective ripple attenuation and stable voltage under load.
• High Ripple-Current Capability — Rated ripple current of 1.361 A at 120 Hz and 1.815 A at 10 kHz supports both low- and high-frequency switching environments.
• Automotive-Grade Reliability — AEC-Q200 rating for applications requiring automotive-level component qualification.
• Temperature & Lifetime — Operating range from −55 °C to 105 °C and a rated lifetime of 5000 hours at 105 °C for prolonged high-temperature operation.
• Package & Mounting — Radial lead, can-style package with 5 mm lead spacing for through-hole mounting and compact board placement (L: 3.05 × D: 1 cm).
• Polarized Electrolytic — Polarized design with capacitance tolerance of −20% to +20% for predictable bulk capacitance in power designs.

Typical Applications

• Switching Power Supplies — Bulk smoothing and ripple suppression in DC–DC converters and switch-mode power supplies where low impedance and ripple handling are required.
• Automotive Electronics — Power filtering and energy storage in automotive modules, leveraging the AEC-Q200 rating and wide −55 °C to 105 °C temperature range.
• Power Management Modules — Decoupling and transient energy support in power distribution and regulator circuits that demand durable, high-capacitance components.

Unique Advantages

• Compact Bulk Capacitance — 680 µF in a 3.05 × 1 cm can minimizes board area while providing substantial energy storage for power rails.
