Key Features

• Core Electricals – 47 µF nominal capacitance with a tolerance of -20% to +20% at 120 Hz, 20°C; rated voltage 20 V.
• Low Loss & Low ESR – tanδ = 0.12 (20°C, 120 Hz) and ESR = 25 mΩ measured at 20°C/100 kHz, supporting efficient energy transfer and reduced heat generation.
• High Ripple Capability – Low-frequency ripple current of 170 mA (120 Hz) and high-frequency ripple current of 1.7 A (300 kHz) for demanding switching environments.
• Wide Temperature Range – Operational from -55°C to 125°C, suitable for designs that encounter extreme ambient conditions.
• Long Endurance – Rated life of 3000 hours at 125°C, ensuring prolonged service in elevated-temperature applications.
• Surface-Mount Radial Can Packaging – φ8 × 10 mm SMD radial can with embossed carrier taping and moisture-proof packing for automated assembly and storage.
• Polarized, SMD Mounting – Polarized construction for power filtering and decoupling; optimized for surface-mount processes including lead-free reflow up to a 260°C peak.
• Regulatory Compliance – RoHS directive compliant.

Typical Applications

• Switching Power Supplies – Low ESR and high high-frequency ripple current make this capacitor suitable for output filtering and smoothing in DC–DC converters.
• Point-of-Load Decoupling – Compact SMD radial can and strong high-frequency performance support decoupling of regulators and local power rails.
• Industrial Embedded Systems – Wide -55°C to 125°C operating range and 3000-hour endurance at 125°C support stable operation in elevated-temperature environments.
• General-Purpose Power Conditioning – Polarized conductive-polymer construction provides reliable capacitance and low leakage for a range of general-purpose applications.
