RKS1D820MCNAHGGS

The RKS1D820MCNAHGGS is an 82 µF, 20 V surface-mount conductive polymer aluminum electrolytic capacitor designed for applications that demand high ripple handling and reliable high-temperature endurance. As a polarized SMD can-type capacitor with solid conductive polymer electrolyte, it targets SMD power modules and high-frequency power systems where low ESR and extended life at elevated temperatures are required.

Key value propositions include low equivalent series resistance (30 mΩ at 100 kHz), high allowable ripple current (1.6 A at 300 kHz), and an extended endurance rating of 3000 hours at 125°C — enabling compact, robust power delivery in high-stress environments.

Key Features

• Capacitance & Voltage — 82 µF rated capacitance with a rated voltage of 20 V and a capacitance tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Loss Angle (tan δ) — tanδ of 0.12 at 20°C, 120 Hz, providing predictable loss characteristics for AC and ripple conditions.
• Low ESR & High-Frequency Performance — ESR of 30 mΩ measured at 20°C/100 kHz, supporting high-frequency decoupling and switching regulator stability.
• 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 to handle sustained AC stress in power circuits.
• Leakage & Endurance — Leakage current specified at 100 µA and load life of 3000 hours at 125°C, providing long-term reliability in elevated-temperature installations.
• Wide Operating Temperature — Rated for -55°C to +125°C to accommodate demanding thermal environments.
• SMD Package & Assembly — Compact φ8 × 7.7 mm can-style SMD (radial, can - SMD) with recommended land size of 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow soldering (260°C peak).
• Compliance — RoHS compliant.

Typical Applications

• Power Supply Output Filtering — Low ESR (30 mΩ) and 82 µF capacitance make this capacitor suitable for smoothing and stabilizing DC rails in switching power supplies.
• DC–DC Converter Output — High-frequency ripple capability (1.6 A at 300 kHz) supports compact converter outputs and high switching-frequency topologies.
• Industrial Power Modules — 3000 hours life at 125°C and a -55°C to 125°C operating range enable use in industrial power assemblies operating under elevated temperatures.
• High-Ripple, High-Temperature Environments — Combined ripple current ratings and high-temperature endurance make it suitable for boards with sustained AC stress and thermal cycling.

Unique Advantages

• High ripple handling: Rated for 1.6 A at 300 kHz (and 160 mA at 120 Hz), enabling reliable performance under sustained AC loading common in switching circuits.
• Low ESR: 30 mΩ at 100 kHz reduces loss and heat generation at high frequencies, improving converter efficiency and stability.
• Extended high-temperature life: 3000 hours at 125°C provides proven endurance for thermally demanding applications.
• SMD-ready assembly: Compact φ8 × 7.7 mm can, embossed carrier taping, moisture-proof packing, and compatibility with 260°C lead-free reflow simplify automated production and board-level integration.
• Predictable leakage and loss characteristics: Specified leakage current (100 µA) and tanδ (0.12 at 20°C/120 Hz) support deterministic thermal and electrical design margins.
• Regulatory compliance: RoHS compliance supports inclusion in lead-free manufacturing flows.
