Key Features

• Dielectric / Core: Conductive polymer aluminum solid electrolytic construction for stable capacitance and improved ripple handling.
• Capacitance & Voltage: 180 µF nominal capacitance at a rated voltage of 16 V with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Low Loss & ESR: tanδ of 0.12 (20°C, 120 Hz) and ESR of 23 mΩ measured at 100 kHz, supporting efficient power conversion and decoupling.
• High Ripple Current: Rated ripple current of 180 mA at 120 Hz (low frequency) and 1.8 A at 300 kHz (high frequency) for robust filtering in switching environments.
• Leakage Current: Specified leakage current of 864 µA (measured after initial application conditions).
• Temperature & Endurance: Operating temperature −55°C to +125°C with a load life of 3000 hours at 125°C.
• Package & Mounting: Surface-mount radial can (φ8 × 6.7 mm) with recommended land size 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture-proof packing.
• Assembly Compatibility: SMD type designed to meet lead-free reflow soldering conditions with a peak of 260°C.
• Compliance & Availability: RoHS compliant and in mass production.

Typical Applications

• Switching power supplies: Use for output filtering and decoupling where high ripple current (1.8 A at 300 kHz) and low ESR reduce voltage ripple and improve regulator stability.
• Point-of-load bulk decoupling: Provides local energy storage and smoothing on power rails requiring 180 µF capacitance at 16 V in compact SMD formats.
• High-temperature electronics: Suitable for modules and assemblies that operate up to +125°C and require long-term endurance (3000 hours at 125°C).

Unique Advantages

• High ripple tolerance: 1.8 A ripple capability at 300 kHz combined with low ESR (23 mΩ) enables effective suppression of switching noise without excessive heating.
• Extended high-temperature life: Rated for 3000 hours at 125°C, offering predictable end-of-life behavior for thermally demanding designs.
• Compact SMD can package: φ8 × 6.7 mm footprint with a defined surface-mount land pattern (8.3 × 8.3 mm) simplifies PCB layout for space-constrained power boards.
• Assembly-ready packaging: Supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow (260°C peak) for automated manufacturing.
• Stable electrical characteristics: Specified tanδ (0.12 at 20°C/120 Hz) and controlled leakage current (864 µA) support predictable filtering and timing performance.
• Regulatory compliance: RoHS compliant for use in regulated designs and supply chains.
