Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with tolerance −20% to +20% (measured at 120 Hz, 20 °C) and a 20 V rated voltage.
• Dielectric & Construction — Conductive‑polymer aluminum solid electrolytic construction for stable performance and low-loss operation.
• Low ESR & High‑Frequency Performance — ESR specified at 30 mΩ measured at 100 kHz and 20 °C; tan δ of 0.12 at 120 Hz and 20 °C.
• Ripple Current Capability — Low‑frequency ripple current 160 mA at 120 Hz and high‑frequency ripple current 1.6 A at 300 kHz to support demanding power stages.
• Temperature & Endurance — Rated for −55 °C to 125 °C with a load life of 3000 hours at 125 °C.
• Leakage Current — Specified leakage current of 180 µA after application of rated voltage.
• Package & Assembly — SMD radial can (φ8 × 7.7 mm, D × L) with recommended land pattern 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture‑proof packing and compatible with lead‑free reflow up to a 260 °C peak.
• Compliance — RoHS‑compliant.

Typical Applications

• Power‑supply output smoothing — Low ESR and high ripple current capability make this capacitor suitable for smoothing outputs of switching regulators and reducing output voltage ripple.
• DC–DC converters — Compact 180 µF capacitance with stable high‑frequency performance supports bulk and output filtering in compact converter modules.
• Industrial electronics — Extended operation to 125 °C and a 3000‑hour load life at that temperature suit demanding industrial power electronics and environments with elevated ambient temperatures.
• High‑frequency decoupling — Specified ESR at 100 kHz and low tan δ support decoupling roles in high‑frequency power stages.

Unique Advantages

• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz reduces conduction losses and helps maintain regulator stability.
• High ripple handling: 1.6 A at 300 kHz (HF) and 160 mA at 120 Hz (LF) enable reliable performance under continuous ripple stress.
• High‑temperature endurance: Rated for −55 °C to 125 °C with a specified 3000‑hour load life at 125 °C for long service life in hot environments.
• SMD‑ready assembly: Compact φ8 × 7.7 mm can, recommended land pattern, embossed carrier taping, moisture‑proof packing, and compatibility with lead‑free reflow to 260 °C streamline automated manufacturing.
• Predictable dielectric behavior: Specified tan δ (0.12 at 120 Hz, 20 °C) and defined leakage current (180 µA) simplify design verification and margining.
• Regulatory compliance: RoHS‑compliant material set for environmental requirements.
