• Long Endurance — Rated for 3000 hours at 125 °C, with defined limits for capacitance, tan δ and ESR after endurance testing.
• Wide Operating Temperature — −55 °C to 125 °C operating range for thermal robustness in demanding environments.
• SMD Can Package & Dimensions — Radial can SMD package, size φ10 × 12.4 mm (L: 12.4 mm × D: 10 mm), designed for surface-mount assembly.
• Reflow Compatibility — Lead‑free reflow soldering correspondence up to a 260 °C peak as defined in the product series datasheet.
• Packaging — Supplied in embossed carrier taping with moisture‑proof packing for automated assembly.
• RoHS Compliant — Meets RoHS requirements as stated in the product data.

Typical Applications

• General Purpose SMD Electronics — Provides high capacitance and low ESR for a variety of surface-mount designs that require stable bulk capacitance in a compact can package.
• High-Temperature Systems — With an operating range to 125 °C and 3000-hour endurance at 125 °C, suitable for applications exposed to elevated ambient temperatures.
• High-Frequency Circuits — Low ESR at 100 kHz and a 2.0 A ripple rating at 300 kHz support circuits with significant high-frequency ripple currents.

Unique Advantages

• High Capacitance in a Compact SMD Can: 270 µF in a φ10 × 12.4 mm package delivers substantial bulk capacitance while minimizing board area.
• Low ESR for Improved Performance: 20 mΩ ESR at 100 kHz helps reduce voltage ripple and power loss in high-frequency applications.
• Wide Temperature and Long Life: −55 °C to 125 °C operation and 3000 hours of rated-life endurance at 125 °C provide predictable long-term behavior in thermally demanding designs.
• Robust Ripple Handling: Combined low- and high-frequency ripple current ratings (200 mA @ 120 Hz and 2 A @ 300 kHz) support mixed-frequency power environments.
• Assembly-Ready Packaging: Embossed carrier taping with moisture-proof packing simplifies automated pick-and-place and storage handling.
• Standards-Conscious Manufacturing: Lead‑free reflow compatibility and RoHS compliance align with modern production and environmental requirements.
