Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a rated voltage of 35 V and capacitance tolerance of -20% to +20% (measured at 20°C, 120 Hz).
• Conductive-Polymer Aluminum Construction — Solid electrolyte architecture for stable performance and long life under rated conditions.
• Low ESR & High-Frequency Performance — ESR of 20 mΩ measured at 20°C / 100 kHz, supporting high-frequency decoupling and stability in switching regulator environments.
• High Ripple Current Capacity — Low-frequency ripple current of 200 mA (120 Hz) and high-frequency ripple current up to 2000 mA (300 kHz) for demanding power filtering tasks.
• Wide Temperature Range & Endurance — Operating range from -55°C to +125°C with an endurance specification of 3000 hours at 125°C, rated voltage.
• Dissipation Factor & Leakage — tanδ of 0.12 (20°C, 120 Hz) and a measured leakage current of 143 µA for predictable loss and standby behavior.
• Surface-Mount Can Package — Radial can SMD (φ10 × 12.4 mm / L: 1.24 × D: 1.00 cm) suitable for automated placement; packaged in embossed carrier tape with moisture-proof packing. RoHS compliant.

Typical Applications

• Power Supply Filtering — Low ESR (20 mΩ) and up to 2.0 A high-frequency ripple current capability make this capacitor suitable for bulk and decoupling roles on DC‑DC converter outputs and regulator rails.
• Switching Power Modules — Conductive-polymer construction and robust ripple handling support filtering and energy-storage needs in switching power stages used in communications and industrial equipment.
• High-Temperature Electronics — Rated for operation to 125°C with a 3000-hour endurance at that temperature, enabling use in elevated-temperature board environments.
• General-Purpose Board Designs — Polarized surface-mount can format and embossed-tape packaging simplify integration into automated assembly flows for a wide range of electronic products.

Unique Advantages

• Stable High-Temperature Endurance: 3000 hours at 125°C under rated voltage provides predictable lifetime performance for thermal-stressed designs.
• Low ESR for Improved Regulation: 20 mΩ ESR at 100 kHz reduces voltage ripple and improves transient response when used on power rails.
• High-Frequency Ripple Handling: Rated for 2.0 A ripple current at 300 kHz, enabling reliable operation in high-speed switching environments.
• Compact SMD Can Package: φ10 × 12.4 mm form factor in embossed carrier tape supports automated placement while providing significant capacitance in a small footprint.
• Predictable Loss and Leakage: Specified tanδ of 0.12 (20°C, 120 Hz) and leakage current of 143 µA support accurate power-loss budgeting and standby behavior.
• RoHS Compliance and Assembly-Ready Packaging: RoHS-compliant construction and moisture-proof embossed tape packaging streamline manufacturing and environmental compliance.
