RKS1J820MCNAJLGS

The RKS1J820MCNAJLGS is a surface-mount aluminum electrolytic capacitor in Nichicon’s RKS series, designed for general-purpose electronic power applications. It combines a high nominal capacitance of 82 µF with a 63 V rating and conductive polymer aluminum solid electrolyte construction for stable performance across wide temperature and frequency ranges.

Engineered for reliability in demanding thermal environments, this part offers a −55°C to 125°C operating range and a rated endurance of 3000 hours at 125°C, making it suitable for board-level power filtering and high-frequency ripple handling where long life and consistent ESR are required.

Key Features

• Capacitance & Tolerance — 82 µF nominal capacitance with tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Rated Voltage — 63 V DC rating for medium-voltage power rails and bulk decoupling tasks.
• Low ESR & Frequency Performance — ESR of 30 mΩ measured at 20°C/100 kHz and tangent of loss angle (tan δ) of 0.12 (20°C, 120 Hz) to support high-frequency decoupling.
• Ripple Current Handling — 140 mA at 120 Hz (low frequency) and 1.4 A at 300 kHz (high frequency) for effective ripple suppression across a broad spectral range.
• Thermal Endurance — Rated for operation from −55°C to 125°C and specified load life of 3000 hours at 125°C.
• Leakage Current — Specified leakage current of 258 µA under rated conditions.
• SMD Can Package & Packaging — Radial, can-type SMD (φ10 × 12.4 L) supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS Compliance — Series datasheet indicates compliance with RoHS directives.

Typical Applications

• General-purpose power filtering — Bulk and output filtering on board-level power supplies where 82 µF at 63 V is required.
• Surface-mount board designs — SMD radial can package with embossed carrier taping simplifies pick-and-place and reflow assembly for volume production.
• High-temperature electronics — Suitable for designs exposed to elevated ambient temperatures, supported by a −55°C to 125°C range and 3000-hour endurance at 125°C.
• High-frequency decoupling — Low ESR (30 mΩ at 100 kHz) and 1.4 A high-frequency ripple capability make it suitable for suppressing high-frequency ripple on DC-DC converters and switching nodes.

Unique Advantages

• Long high-temperature life: 3000 hours endurance at 125°C provides predictable aging characteristics for thermal-stressed designs.
• High ripple capacity across frequencies: Combined low-frequency and high-frequency ripple ratings (140 mA at 120 Hz and 1.4 A at 300 kHz) support mixed-frequency power systems.
• Stable high-frequency behavior: 30 mΩ ESR at 100 kHz and tan δ specified at 0.12 (20°C, 120 Hz) help maintain voltage stability and reduce loss in switching applications.
• Production-ready SMD packaging: Embossed carrier taping and moisture-proof packing enable automated assembly and storage management for high-volume manufacturing.
• Wide operating temperature range: −55°C to 125°C operation supports applications in thermally challenging environments.
• Clear specification set: Explicit leakage, ESR, ripple, and endurance ratings simplify selection and design verification.
