Key Features

• Capacitance & tolerance — 180 µF nominal with a tolerance of -20% to +20% measured at 20°C, 120 Hz.
• Rated voltage — 16 V DC.
• Low ESR — 25 mΩ ESR specified at 20°C and 100 kHz, improving high-frequency performance.
• High ripple capability — Low-frequency ripple current 170 mA (120 Hz) and high-frequency ripple current 1.7 A (300 kHz) for demanding power-conditioning roles.
• Loss characteristics — tan δ (dissipation factor) 0.12 at 20°C, 120 Hz.
• Leakage current — Specified leakage current of 144 µA after rated voltage application.
• Wide temperature range — Rated for operation from -55°C to +125°C.
• Long endurance — Load life of 3000 hours at 125°C under rated voltage conditions.
• SMD can package — Radial, can-style SMD (φ8 × 10L; size L: 1 × D: 0.8 cm) supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS compliant — Conforms to RoHS directives as stated in product documentation.

Typical Applications

• General-purpose power filtering — Suitable for bulk decoupling and smoothing where higher capacitance and low ESR improve power stability.
• Point-of-load and regulator support — High allowable ripple current and low ESR make it useful for supporting DC–DC converters and regulator outputs.
• Compact SMD assemblies — Can-style SMD packaging and tape-and-reel compatible packing enable integration into space-constrained, high-density PCBs.

Unique Advantages

• Reduced power loss: The 25 mΩ ESR at 100 kHz minimizes resistive loss and heat generation in high-frequency applications.
• Improved ripple handling: Rated ripple currents (170 mA at 120 Hz and 1.7 A at 300 kHz) support robust transient and switching performance.
• High-temperature endurance: 3000-hour load life at 125°C provides predictable aging and reliable long-term operation under elevated ambient conditions.
• Compact SMD form factor: φ8 × 10L can-style SMD package and embossed carrier taping simplify automated placement and reflow assembly.
• Stable electrical characteristics: Specified tan δ and leakage current values deliver consistent performance for design validation and qualification.
• Regulatory compliance: RoHS compliance supports use in environments requiring restricted substance adherence.
