• Rated Voltage 6.3 V rated voltage suitable for low-voltage power rails.
• Low ESR 10 mΩ ESR measured at 20°C/100 kHz, supporting low-loss performance at high frequencies.
• High Ripple Current 550 mA at 120 Hz (low frequency) and 5.5 A at 300 kHz (high frequency), with frequency coefficients defined in the series datasheet.
• Leakage Current 774 µA leakage current (measured at 25°C after 2 minutes).
• Temperature & Endurance Operating range −55°C to 105°C and 2000 hours endurance at 105°C, rated voltage.
• Package & Mounting Radial lead can, case size φ10×12.5 mm, lead spacing 5 mm (±0.5 mm), supplied bulk/no terminal forming and bag-packed for mass production.

Typical Applications

• General-purpose electronics Suitable for board-level energy storage and general-purpose capacitor needs in a variety of electronic assemblies.
• High-frequency power circuits Supports high-frequency ripple handling—5.5 A at 300 kHz—and low ESR (10 mΩ at 100 kHz) for demanding switching environments.
• Through-hole assemblies Radial-lead package (φ10×12.5 mm) with 5 mm lead spacing for straightforward through-hole mounting and prototyping or legacy PCB designs.
• High-temperature endurance designs Rated for −55°C to 105°C operation with 2000 hours endurance at 105°C for designs requiring sustained elevated-temperature performance.

Unique Advantages

• High ripple capability: 5.5 A rated ripple at 300 kHz and 550 mA at 120 Hz reduce voltage ripple and thermal stress in high-frequency power stages.
• Low ESR for improved efficiency: 10 mΩ ESR (20°C/100 kHz) lowers power loss and helps maintain stable voltage under dynamic load.
• Compact, board-friendly package: φ10×12.5 mm can with 5 mm lead spacing provides a high-capacitance solution in a small through-hole footprint.
• Robust thermal endurance: −55°C to 105°C operating range and 2000 hours endurance at 105°C support long-term reliability in elevated-temperature environments.
• Predictable leakage behavior: Specified leakage current (774 µA) allows designers to budget standby currents in power-sensitive designs.
