• Reflow Compatible — SMD type designed for lead‑free reflow soldering up to 260°C peak (per series soldering profile).
• Compliance — RoHS compliant; status: mass production.

Typical Applications

• Power Supply Decoupling — Low ESR and high allowable ripple current provide effective smoothing and decoupling on power rails.
• DC‑DC Converters and Power Modules — Compact SMD can and high ripple capability support local energy storage and filtering in converter outputs.
• High‑Temperature Electronics — Rated for operation to 125°C with a 3000‑hour endurance at that temperature for industrial and thermally demanding environments.
• High‑Frequency Filtering — Measured ESR at 100 kHz and specified high‑frequency ripple current make it suitable for high‑frequency noise attenuation and bypassing.

Unique Advantages

• Extended high‑temperature life: 3000 hours at 125°C provides predictable longevity in hot environments, easing thermal design constraints.
• Compact SMD can footprint: φ6.3 × 5.8 mm size with embossed carrier taping simplifies automated placement while saving board area.
• Low ESR for efficient filtering: 120 mΩ at 100 kHz reduces voltage ripple and losses in power paths, improving regulator stability.
• High ripple handling: Specified ripple currents (70 mA @120 Hz; 700 mA @300 kHz) support both low‑ and high‑frequency power conditioning needs.
• Reflow process compatibility: Designed to withstand lead‑free reflow up to 260°C peak for standard SMT assembly flows.
• RoHS compliant and production ready: Mass production status and environmental compliance facilitate supply continuity and regulatory alignment.
