• High Ripple Current Capability — 500 mA at 120 Hz (low frequency) and 5 A at 300 kHz (high frequency) for demanding ripple filtering and switching applications.
• Leakage Current — 864 µA measured after 2 minutes at 20°C, for controlled DC leakage behavior.
• Endurance & Temperature Range — 2000 hours rated life at 105°C; operating range −55°C to 105°C for thermal reliability in stressed environments.
• Radial Lead Package — φ8 × 11.5 mm can, lead spacing 3.5 mm ±0.5 mm, radial-lead mounting in bulk bag packing for through-hole assemblies.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• General-purpose power electronics — Provides bulk energy storage and smoothing where stable capacitance and long life are required.
• Power-supply filtering — Low ESR and high ripple-current ratings make this part suitable for filtering in switching regulator and converter outputs.
• Decoupling and bulk bypass — High capacitance in a compact radial package helps stabilize low-voltage rails and reduce supply noise.
• Industrial and consumer electronics — Robust temperature range and endurance support use in assembled products requiring reliable power-conditioning components.

Unique Advantages

• High capacitance in a compact can — 270 µF in a φ8 × 11.5 mm radial package conserves board space while providing substantial charge storage.
