• Conductive Polymer Dielectric — Solid conductive polymer aluminum construction for stable electrical characteristics and improved ripple performance.
• Low ESR & High Ripple Handling — ESR of 30 mΩ at 20°C/100 kHz, with ripple current ratings of 160 mA at 120 Hz and 1.6 A at 300 kHz.
• Thermal and Endurance Performance — Rated operating temperature range of −55°C to +125°C and a load life of 3000 hours at 125°C.
• Leakage & Loss Characteristics — Leakage current specified at 100 µA and tanδ (loss tangent) of 0.12 measured at 20°C, 120 Hz.
• Surface-Mount Radial Can Package — Compact φ8 × 8.7 mm can (L: 8.7 × D: 8 mm) with surface-mount land recommendation of 8.3 × 8.3 mm; supplied in embossed carrier tape with moisture-proof packing for assembly.
• Reflow Compatibility — SMD type designed for lead-free reflow soldering (soldering profile per specification up to 260°C peak).
• RoHS Compliance — Series-level documentation indicates compliance with RoHS directives as provided in the datasheet.

Typical Applications

• Power conversion output filtering — Low ESR and high ripple-current capability make this capacitor suitable for smoothing outputs in compact DC–DC converters and power modules.
• High-frequency decoupling — Stable performance at 100 kHz and high-frequency ripple rating support decoupling in high-speed power stages.
• Industrial and harsh-environment electronics — Extended operating range to 125°C and a 3000-hour life at that temperature suit thermally demanding applications.

Unique Advantages

• High ripple-current tolerance: 1.6 A at 300 kHz and 160 mA at 120 Hz enable reliable handling of dynamic load currents in power circuits.
• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz reduces loss and heat generation in high-frequency applications.
• Extended high-temperature endurance: 3000 hours at 125°C provides predictable lifetime performance in elevated-temperature environments.
• Compact SMD can package: φ8 × 8.7 mm footprint with tape-and-reel packaging simplifies automated assembly for space-constrained boards.
• Solid conductive polymer construction: Offers stable electrical characteristics and controlled leakage for reliable long-term operation.
• Reflow-capable and RoHS-aligned: Designed for lead-free reflow processes and documented RoHS compliance for modern assembly flows.
