Key Features

• Capacitance & Voltage: 680 µF nominal capacitance at a rated voltage of 63 V, with capacitance tolerance of −20% to +20%.
• Low Impedance: Specified impedance of 100 mOhm to help reduce ripple and improve power‑stage stability.
• High Ripple Current Capability: Rated ripple currents of 1.62 A at 120 Hz and 2.16 A at 10 kHz, supporting both low‑ and high‑frequency switching environments.
• Automotive Reliability: AEC‑Q200 rated for automotive use with a specified lifetime of 8000 hours at 105°C.
• Wide Temperature Range: Operates from −55°C to 105°C for extended thermal robustness.
• Radial Through‑Hole Package: Radial lead can with 7.5 mm lead spacing, 2.5 cm length and 1.6 cm diameter for compact, serviceable mounting.

Typical Applications

• Switching Power Supplies: Bulk and output filtering in switching regulators where compact, low‑impedance capacitance is required.
• Automotive Electronics: Power smoothing and decoupling in automotive modules, leveraging the AEC‑Q200 qualification and 105°C endurance.
• DC‑DC Converters: Energy storage and ripple suppression in point‑of‑load and intermediate bus converters.
• Power Rail Stabilization: Filtering and transient support for power rails in industrial and embedded systems.

Unique Advantages

• Compact high‑value capacitance: 680 µF in a small radial can (L: 2.5 cm × D: 1.6 cm) saves board space while providing significant energy storage.
• Effective ripple management: Low impedance (100 mOhm) together with rated ripple currents at 120 Hz and 10 kHz improves noise suppression in switching stages.
• Designed for harsh environments: −55°C to 105°C operating range and 8000 hours endurance at 105°C support long service life in elevated temperatures.
• Automotive‑grade qualification: AEC‑Q200 rating provides an explicit baseline for use in automotive electronic applications.
• Serviceable through‑hole format: Radial lead mounting with 7.5 mm lead spacing simplifies winding, replacement, and mechanical retention in assemblies.
