Key Features

• Capacitance & Voltage — 68 µF capacitance with a rated voltage of 20 V and capacitance tolerance of ±20% (–20%~20%).
• Low Loss & Dissipation — Tangent of loss angle (tan δ) of 0.12 measured at 20°C, 120 Hz, supporting efficient energy handling in AC components.
• Low ESR — ESR of 25 mΩ specified at 20°C, 100 kHz, enabling reduced heat generation and improved ripple performance.
• High Ripple Current — Low-frequency ripple current of 170 mA (120 Hz) and high-frequency ripple current of 1.7 A (300 kHz) for effective smoothing in power circuits.
• Reliability & Life — Rated for 3000 hours at 125°C; operating temperature range from –55°C to 125°C for extended durability under thermal stress.
• Leakage Current — Specified leakage current of 100 µA after standard conditioning.
• Surface-Mount Packaging — Radial can SMD package, size φ8 × 10 mm (L: 1 cm × D: 0.8 cm), supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS Compliant — Meets RoHS directive requirements as specified in the product documentation.

Typical Applications

• General-purpose power supply filtering — Low ESR and 1.7 A high-frequency ripple current make this capacitor suitable for smoothing and decoupling in DC-DC converters and power rails.
• High-temperature electronics — The –55°C to 125°C range and 3000-hour life at 125°C support use in designs exposed to elevated operating temperatures.
• Automated SMD assembly — Embossed carrier taping and moisture-proof packing, plus compatibility with lead-free reflow profiles, simplify high-volume surface-mount production.

Unique Advantages

• High ripple capability: 1.7 A high-frequency ripple and low ESR (25 mΩ) reduce voltage ripple and thermal stress on the capacitor in power circuits.
• Thermal endurance: 3000 hours at 125°C and a wide operating temperature range provide predictable lifetime behavior in hot operating environments.
• Compact SMD form factor: φ8 × 10 mm radial can SMD package offers a small PCB footprint while retaining substantial capacitance and current handling.
• Manufacturing-ready packaging: Embossed carrier taping and moisture-proof packing streamline pick-and-place and reflow processes for volume assembly.
• Measured electrical characteristics: Specified tan δ, ESR at 100 kHz, and leakage current figures enable designers to model performance precisely in system simulations.
