Key Features

• Dielectric / Electrolyte — Conductive polymer aluminum solid electrolytic construction for stable performance and low ESR.
• Capacitance & Tolerance — 68 µF with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 63 V working voltage suitable for mid-voltage power rails.
• Low Loss & Dissipation — tanδ (DF) = 0.12 at 20°C, 120 Hz for low loss in AC conditions.
• Low ESR & High Ripple Handling — ESR 30 mΩ (20°C, 100 kHz); high-frequency ripple current 1.4 A (300 kHz) and low-frequency ripple current 140 mA (120 Hz).
• Leakage Current — 214 µA measured after standard conditioning, supporting predictable bias behavior.
• Thermal Endurance — Rated for operation from -55°C to 125°C with a load life of 3000 hours at 125°C.
• Package & Mounting — Surface-mount radial can (φ10 × 10L); supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Reflow Compatibility — Designed for lead-free reflow soldering peak up to 260°C per series recommendations.
• Regulatory — Series-level compliance with RoHS directives (2011/65/EU, (EU)2015/863) as stated in the product literature.

Typical Applications

• General-purpose electronics — Surface-mount designs that require a 63 V-rated, 68 µF capacitor for bulk capacitance and decoupling in compact assemblies.
• Power supply filtering — Low ESR (30 mΩ) and high ripple-current capability make it suitable for smoothing and filtering on intermediate power rails.
• High-frequency decoupling — 1.4 A high-frequency ripple current rating supports decoupling in circuits with switching or high-frequency components.
• Industrial and high-temperature environments — Operation from -55°C to 125°C and 3000 h life at 125°C suit designs requiring extended thermal endurance.

Unique Advantages

• Low-loss polymer electrolyte — Delivers reduced dissipation (tanδ = 0.12) for improved AC performance compared to higher-loss solutions.
• High ripple-current capability — 1.4 A at high frequency and 140 mA at low frequency support robust power smoothing and transient handling.
• Compact SMD can — φ10 × 10L package provides significant capacitance in a surface-mount form factor for space-constrained designs.
• Extended high-temperature life — 3000 hours at 125°C gives predictable longevity for demanding thermal environments.
• Manufacturing-ready supply — Embossed carrier taping and moisture-proof packing simplify automated placement and handling.
• Predictable leakage behavior — Specified leakage current (214 µA) and datasheet conditioning procedures support reliable bias design.
