• Leakage and Loss Characteristics: Specified leakage current of 125 µA and tanδ (DF) of 0.12 measured at 20°C, 120 Hz.
• Packaging: Supplied in embossed carrier tape with moisture-proof packing for automated assembly.
• RoHS Compliance: Conforms to RoHS directive requirements.

Typical Applications

• Power Conversion and DC‑DC Modules: Low ESR (30 mΩ) and 1.6 A high-frequency ripple capability make this capacitor suitable for bulk and output filtering in compact power modules.
• Switch‑Mode Power Supplies (SMPS): High allowable ripple current and stable performance to 125°C support use on high-frequency SMPS outputs and input filters.
• Industrial Power Electronics: Extended 3000-hour life at 125°C and −55°C to 125°C operating range address thermal and reliability demands in industrial control and power subsystems.

Unique Advantages

• High ripple handling: 1.6 A at 300 kHz and 160 mA at 120 Hz enable effective smoothing in high-frequency, high-current circuits.
• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz reduces dissipation and supports tighter voltage regulation in power circuits.
• Thermal endurance: 3000 hours at 125°C provides extended operational life in elevated-temperature applications.
• Surface-mount convenience: Compact φ8 × 6.7 mm SMD can and embossed tape packaging simplify automated placement and reduce board area compared with through-hole alternatives.
• Reflow-ready: Compatible with lead-free reflow profiles up to 260°C peak for modern assembly processes.
• Regulated leakage and dissipation: Specified leakage current (125 µA) and tanδ (0.12) provide predictable behavior for precision power designs.
