RKS1D820MCNAHFGS

The RKS1D820MCNAHFGS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package (φ8 × 6.7 mm). It combines high capacitance density with low equivalent series resistance and elevated ripple-current capability for demanding power-electronic applications.

Designed for compact power stages and high-ripple circuits, this RKS-series part delivers measurable benefits for engineers needing low ESR, long high-temperature life, and SMD-compatible assembly and packaging.

Key Features

• Capacitance & Tolerance — 82 µF nominal with a tolerance of −20% to +20% at 120 Hz, 20°C.
• Rated Voltage — 20 V DC steady-state rating suitable for common low-voltage rails.
• Low ESR — 30 mΩ measured at 20°C / 100 kHz, enabling effective high-frequency filtering and reduced conduction losses.
• High Ripple Current — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency), supporting heavy AC components on DC rails.
• Wide Temperature & Long Life — Operating range −55°C to 125°C with a rated endurance of 3000 hours at 125°C.
• Loss Characteristics — tanδ (DF) = 0.12 measured at 20°C and 120 Hz for predictable dissipation behavior.
• Leakage Current — Specified max leakage of 100 µA after rated-voltage application.
• SMD Radial Can Package — φ8 × 6.7 mm can size with recommended land pattern 8.3 × 8.3 mm; supplied in embossed carrier tape with moisture-proof packing for automated placement.
• RoHS Compliant — Manufactured in accordance with RoHS requirements.
• Reflow Capability (Series-Level) — RKS-series SMD types are specified for lead-free reflow conditions up to a 260°C peak (refer to series datasheet for profile limits).

Typical Applications

• Power Supply Filtering — Bulk decoupling and smoothing on 20 V rails where high ripple currents and low ESR improve voltage stability and reduce heat.
• DC–DC Converter Output Stages — Output filtering in compact converter modules benefiting from 30 mΩ ESR at switching frequencies.
• Power Modules and Industrial Electronics — High-temperature endurance (3000 h at 125°C) and wide operating range (−55°C to 125°C) for robust performance in thermally stressed environments.

Unique Advantages

• High ripple-current handling: Rated up to 1.6 A at 300 kHz and 160 mA at 120 Hz, enabling the capacitor to absorb significant AC components in compact power designs.
• Low ESR for efficient filtering: 30 mΩ at 100 kHz lowers conduction losses and improves transient response in high-frequency circuits.
• Long high-temperature life: 3000 hours at 125°C provides predictable endurance for designs exposed to elevated operating temperatures.
• SMD-ready packaging: Radial can SMD form factor with embossed carrier taping and moisture-proof packing simplifies automated assembly and handling.
• Controlled dissipation: tanδ of 0.12 at 20°C/120 Hz gives consistent dielectric loss characteristics for thermal management considerations.
• Regulatory compliance: RoHS-compliant construction supports environmental and regulatory requirements.
