• SMD Package & Mounting Compact radial can SMD package with dimensions φ6.3 × 5.8 mm (D × L) and surface mount land size 6.6 × 6.6 mm; supplied in embossed carrier tape with moisture‑proof packing for automated assembly.
• Manufacturing & Compliance Designed for lead‑free reflow soldering profiles (260 °C peak correspondence) and RoHS compliant construction.

Typical Applications

• Power supply output filtering — Low ESR and 900 mA high-frequency ripple capability make it suitable for smoothing outputs of compact DC‑DC converters and point‑of‑load modules.
• DC‑DC converter input/output stages — High allowable ripple current and conductive polymer chemistry support stable performance in switching regulator stages.
• High-frequency decoupling — 50 mΩ ESR at 100 kHz and specified tan δ support effective decoupling at high switching frequencies.
• High-temperature electronics — Rated life of 3000 hours at 125 °C and wide −55 °C to 125 °C operating range for applications exposed to elevated ambient temperatures.

Unique Advantages

• High ripple tolerance: 900 mA at 300 kHz and 90 mA at 120 Hz ratings allow direct specification against ripple requirements for switching power stages.
• Low ESR for efficient filtering: 50 mΩ ESR at 100 kHz reduces voltage ripple and power loss in power delivery networks.
• Compact SMD footprint: φ6.3 × 5.8 mm can saves PCB space while providing electrolytic capacitance in a surface-mount form factor.
• Extended high-temperature life: 3000 hours at 125 °C supports designs that must maintain performance under prolonged thermal stress.
• Assembly-ready packaging: Embossed carrier tape and moisture‑proof packing streamline automated pick-and-place and reflow processes.
• Lead‑free reflow capable and RoHS compliant: Suited to lead‑free manufacturing processes (260 °C peak correspondence) and regulated material requirements.
