RKS1V820MCNAHHGS

The RKS1V820MCNAHHGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series. It delivers 82 µF capacitance at a 35 V rating with low equivalent series resistance and specified high-frequency performance for power-electronics applications.

Designed for demanding thermal and ripple environments, this SMD radial-can capacitor supports an extended operating range (−55 °C to 125 °C) and a 3000-hour load life at 125 °C, offering durable decoupling and energy-buffering where low ESR and long-term reliability are required.

Key Features

• Capacitance & Tolerance: 82 µF nominal with tolerance −20% to 20% at 120 Hz, 20 °C for predictable filtering and bulk energy storage.
• Rated Voltage: 35 V DC rating suitable for mid-voltage power rails and converters.
• Low ESR & High-Frequency Performance: ESR 30 mΩ measured at 20 °C/100 kHz and specified high-frequency ripple current of 1.6 A at 300 kHz, enabling reduced loss and effective high-frequency decoupling.
• Ripple Current Capability: Low-frequency ripple current 160 mA at 120 Hz and high-frequency ripple current 1.6 A at 300 kHz to support both bulk and switching-domain ripple demands.
• Thermal Endurance: Rated operating temperature −55 °C to 125 °C with a rated life of 3000 hours at 125 °C, supporting extended operation in hot environments.
• Leakage & Loss Characteristics: Specified leakage current 143 µA and tanδ (loss tangent) 0.12 at 20 °C, 120 Hz for controlled leakage and loss behavior.
• SMD Radial Can Package: Compact φ8 × 8.7 mm can with surface-mount land recommendation (8.3 × 8.3 mm) and embossed carrier taping with moisture-proof packing for SMT assembly.
• Reflow Compatibility & RoHS: Designed for lead-free reflow peak conditions to 260 °C and compliant with RoHS requirements.

Typical Applications

• Power conversion modules: Bulk and output filtering on DC–DC converters where 35 V rating, 82 µF capacitance and low ESR (30 mΩ at 100 kHz) improve transient response and reduce losses.
• High-frequency decoupling: Local decoupling at switching nodes and power stages leveraging 1.6 A ripple capability at 300 kHz and low ESR for stable high-frequency performance.
• Industrial electronics: Energy buffering and ripple suppression in industrial power supplies and control electronics requiring long life at elevated temperatures (3000 h at 125 °C).

Unique Advantages

• High ripple tolerance: Rated for 1.6 A at 300 kHz and 160 mA at 120 Hz, enabling robust performance in switching environments and reducing thermal stress on the capacitor.
• Low ESR operation: 30 mΩ ESR at 100 kHz lowers conduction losses and improves efficiency in power stages and high-frequency decoupling applications.
• Extended high-temperature life: 3000 hours at 125 °C provides long-term reliability for applications exposed to sustained elevated temperatures.
• SMD-ready packaging: Embossed carrier taping and moisture-proof packing support automated SMT assembly and consistent process handling.
• Reflow-compatible: Designed for lead-free reflow soldering (260 °C peak), allowing integration into standard lead-free manufacturing flows.
• Controlled leakage and loss: Specified leakage current (143 µA) and tanδ (0.12 at 120 Hz) enable predictable behavior in biased circuits and system-level power budgeting.
