RKS1E820MCNAHHGS

The RKS1E820MCNAHHGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 82 µF nominal capacitance at a rated voltage of 25 V. Designed for high ripple-current SMD power applications, it delivers low equivalent series resistance and stable performance across a wide operating temperature range.

This part targets compact power delivery and high-frequency decoupling uses where low ESR, high allowable ripple current and extended high-temperature life are required. It is supplied in an embossed carrier taping format with moisture-proof packing for automated assembly.

Key Features

• Capacitance & Tolerance — 82 µF nominal with tolerance of −20% to +20% measured at 20°C, 120 Hz.
• Rated Voltage & Polarization — 25 V rated, polarized electrolytic construction suitable for DC power applications.
• Low ESR & Loss — ESR of 30 mΩ measured at 20°C/100 kHz and tanδ 0.12 (20°C, 120 Hz) for improved high-frequency filtering and reduced heat generation.
• High Ripple Current Capability — Low-frequency ripple current of 160 mA at 120 Hz and high-frequency ripple current of 1.6 A at 300 kHz, supporting demanding power-supply ripple conditions.
• Extended High-Temperature Endurance — Rated for 3,000 hours at 125°C, providing long-term stability in elevated-temperature environments.
• Leakage Current — Specified leakage current of 102 µA (measurement after rated-voltage application conditions), enabling predictable bias behavior in power circuits.
• SMD Package & Assembly — Compact radial can SMD (φ8 × 8.7 mm) with surface-mount land recommendation 8.3 × 8.3 mm; compatible with lead‑free reflow soldering (peak 260°C profile as specified for the series).
• Regulatory — RoHS compliant.

Typical Applications

• Power supply decoupling — Low ESR and high ripple-current capability make this capacitor suitable for bulk and output filtering on DC–DC converters and power modules.
• Point-of-load filtering — Compact SMD can and strong high-frequency performance support decoupling at VRM and point-of-load stages.
• High-temperature electronics — Rated operation to 125°C and 3,000-hour life at that temperature suit equipment that experiences sustained elevated temperatures during operation.

Unique Advantages

• Reduced power dissipation: Low ESR (30 mΩ at 100 kHz) minimizes I²R losses and heating under ripple conditions.
• High ripple handling: 1.6 A high-frequency ripple rating supports aggressive switching regulator environments and high-current decoupling.
• Long life at elevated temperature: 3,000 hours endurance at 125°C provides predictable aging and reliability in hot-board locations.
• Assembly-ready SMD format: Embossed carrier taping with moisture-proof packing simplifies automated placement and reflow processes.
• Predictable leakage behavior: Specified leakage current (102 µA) and conditioning guidance yield consistent bias performance after voltage application.
