RS81E680MCNASQ

The RS81E680MCNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial-leaded can, offering 68 µF capacitance at a 25 V rating. Designed for general-purpose electronic assemblies, it delivers low ESR/ESL characteristics and high ripple-current performance in a compact, low-profile φ6.3×8 mm package.

Key value propositions include low-loss operation (tanδ 0.1 at 120 Hz/20 °C), high-frequency ripple handling (3.5 A at 300 kHz), and extended endurance (5,000 hours at 105 °C), making it suitable where stable power filtering and reliable long-term operation are required.

Key Features

• Conductive polymer aluminum architecture — Solid electrolyte provides low ESR and stable electrical characteristics compared with traditional electrolytic designs.
• Electrical performance — 68 µF capacitance with ±20% tolerance and tanδ of 0.1 (20 °C, 120 Hz) for predictable filtering behavior.
• Low ESR and high ripple capability — ESR of 18 mΩ measured at 20 °C/100 kHz, with rated ripple current of 350 mA at 120 Hz and 3.5 A at 300 kHz for demanding ripple environments.
• Thermal and endurance specs — Operating range −55 °C to 105 °C with a rated life of 5,000 hours at 105 °C under rated voltage.
• Compact radial-lead package — Low-profile φ6.3×8 mm can with 2.5 mm lead spacing suitable for through-hole, radial-leaded assemblies; available in bulk or bag packing.
• Leakage and reliability — Leakage current specified at 510 µA (after 2 minutes at 20 °C), supporting predictable DC behavior in steady-state applications.
• Regulatory status and availability — RoHS compliant and listed as mass production for reliable supply.

Typical Applications

• Power rail smoothing — Low ESR (18 mΩ @100 kHz) and high ripple capability (3.5 A at 300 kHz) support effective decoupling and smoothing of DC supply rails in compact assemblies.
• High-frequency power conversion — tanδ 0.1 and conductive polymer construction make this capacitor suitable for filtering in high-frequency switching converters and point-of-load stages.
• Through-hole radial assemblies — φ6.3×8 mm can with 2.5 mm lead spacing and radial lead format for straightforward placement in through-hole or mixed-technology PCBs.

Unique Advantages

• Low-loss operation: tanδ of 0.1 at 120 Hz/20 °C reduces heat generation and improves efficiency in AC ripple environments.
• High-frequency performance: ESR specified at 18 mΩ (20 °C/100 kHz) and 3.5 A ripple at 300 kHz enable reliable filtering at elevated switching frequencies.
• Extended endurance: 5,000 hours at 105 °C under rated voltage supports long-term stability in thermally demanding applications.
• Space-efficient profile: Low-profile φ6.3×8 mm package offers high performance without large board area impact.
• Predictable leakage: Leakage current specified at 510 µA ensures consistent DC performance after initial voltage application.
• Production-ready supply: RoHS compliant and in mass production, simplifying procurement for volume designs.
