RKS1E820MCNAHJGS

The RKS1E820MCNAHJGS is a surface-mount conductive polymer aluminum electrolytic capacitor delivering 82 µF at a rated voltage of 25 V. Designed for general-purpose power decoupling and smoothing where low ESR and high allowable ripple current are required, it combines high capacitance with long-term thermal endurance.

Its core value proposition is performance under thermal stress: a specified operating range of –55°C to +125°C and a rated load life of 3000 hours at 125°C provide durability for demanding electronic power rails and high-frequency power circuits.

Key Features

• Conductive polymer aluminum construction – Solid electrolyte technology for stable capacitance and reliable performance across temperature.
• Capacitance and tolerance – 82 µF with a tolerance of −20% to +20% at 120 Hz, 20°C.
• Rated voltage – 25 V nominal rating for a wide range of low-voltage power applications.
• Low loss and high-frequency performance – tanδ (loss tangent) of 0.12 (20°C, 120 Hz) and ESR of 27 mΩ measured at 20°C/100 kHz to reduce dissipation in high-frequency environments.
• High ripple handling – Low-frequency ripple current of 160 mA (120 Hz) and high-frequency ripple current up to 1.6 A (300 kHz) to support switching regulators and power stages.
• Leakage current – Specified leakage current of 102 µA after standard conditioning.
• Extended high-temperature life – Rated endurance of 3000 hours at 125°C under rated voltage, with defined limits for capacitance change, tanδ and ESR.
• SMD radial can package – Compact φ8 × 10L radial can designed for surface-mount assembly; supplied in embossed carrier tape with moisture-proof packing for production handling.
• Manufacturing and compliance – Lead-free reflow compatible (peak 260°C, up to two reflow cycles specified) and RoHS compliant.

Typical Applications

• Switching power supplies: Low ESR and high ripple current capability make it suitable for output smoothing and decoupling on DC–DC converters and switching regulators.
• Point-of-load power rails: High capacitance in a compact SMD radial can supports transient response and rail stability for microprocessors and power modules.
• High-frequency power circuits: Measured ESR at 100 kHz and high-frequency ripple rating enable use in circuits operating at elevated switching frequencies.
• Industrial and communications equipment: Wide temperature range (−55°C to +125°C) and 3000-hour life at 125°C support long-term operation in thermally demanding environments.

Unique Advantages

• High ripple tolerance: Rated for 1.6 A at 300 kHz and 160 mA at 120 Hz, enabling reliable operation in switching and high-frequency applications.
• Low ESR for efficiency: 27 mΩ ESR at 100 kHz reduces I²R losses and heat generation in dense power designs.
• Long high-temperature endurance: 3000 hours at 125°C provides a predictable lifecycle for designs exposed to sustained elevated temperatures.
• Compact SMD radial can: φ8 × 10L package combines high capacitance with a small footprint, simplifying board-level integration where space is limited.
• Production-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated assembly and storage.
• RoHS and reflow compatibility: Lead-free reflow capability to 260°C and RoHS compliance support modern manufacturing and environmental requirements.
