Typical Applications

• Power rail decoupling: Low ESR (20 mΩ at 100 kHz) and 2 A high-frequency ripple current capability make this part suitable for decoupling on PCB power rails where low impedance is required.
• DC–DC converter output filtering: 47 µF capacitance with high ripple-current ratings supports smoothing and stabilization of converter outputs under switching conditions.
• General-purpose power modules: Robust thermal endurance (3000 hours at 125 °C) and a wide operating range (-55 °C to 125 °C) suit a variety of general-purpose power designs.

Unique Advantages

• Measured low ESR: Specified 20 mΩ at 100 kHz reduces AC impedance on high-frequency power rails.
• High ripple-current handling: 2 A at 300 kHz enables reliable performance in switching environments and high-frequency applications.
• Extended high-temperature life: Rated 3000 hours at 125 °C for prolonged endurance in elevated-temperature assemblies.
• SMD can with reflow compatibility: φ10 × 10 mm SMD can package supports automated PCB assembly and lead-free reflow up to the specified peak temperature.
• Compact form factor: Small footprint (10 mm × 10 mm) provides a high-capacitance solution for space-constrained layouts.
• Controlled leakage and loss: Leakage current specified at 100 µA and tanδ = 0.12 (20 °C, 120 Hz) for predictable DC and AC behavior.
