RKS1C820MCNAHHGS

The RKS1C820MCNAHHGS is a surface-mount conductive-polymer aluminum solid electrolytic capacitor offering 82 µF capacitance at a 16 V rating. It combines low equivalent series resistance and strong ripple-current capability in a compact radial can SMD package (φ8 × 8.7 mm).

Designed for general-purpose electronic systems, the device targets board-level power smoothing and decoupling where long life, wide operating temperature, and lead-free reflow compatibility are required.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a rated voltage of 16 V and a tolerance of ±20% (–20% to 20%).
• Low ESR — ESR of 30 mΩ measured at 20°C and 100 kHz, reducing voltage ripple and improving transient response in high-frequency applications.
• High Ripple-Current Capability — Rated low-frequency ripple current of 160 mA at 120 Hz and high-frequency ripple current of 1.6 A at 300 kHz to support switching supplies and fast load transients.
• Wide Temperature & Long Life — Operating temperature range from –55°C to 125°C with a rated load life of 3000 hours at 125°C.
• Leakage & Dissipation — Leakage current specified at 100 µA and tan δ (DF) of 0.12 measured at 20°C, 120 Hz for predictable loss characteristics.
• Surface-Mount Package — Radial can SMD package (φ8 × 8.7 mm) supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Lead‑Free Reflow & RoHS — Compatible with lead-free reflow soldering up to a 260°C peak and compliant with RoHS.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where the 1.6 A high-frequency ripple rating and low ESR improve regulation and efficiency.
• DC–DC Converters — Output decoupling for point-of-load converters benefiting from the capacitor’s low ESR and compact SMD radial-can footprint.
• Board-Level Decoupling — Local energy storage and transient suppression in high-frequency circuits enabled by low DF and low ESR at 100 kHz.
• Industrial and Telecom Electronics — General-purpose filtering and energy buffering across –55°C to 125°C and a 3000-hour high-temperature life rating.

Unique Advantages

• Low ESR for improved transient response: 30 mΩ at 100 kHz reduces voltage drop under high-frequency switching conditions.
• High ripple-current tolerance: 1.6 A at 300 kHz supports demanding switching and high-speed power stages.
• Extended high-temperature endurance: 3000 hours at 125°C enables reliable long-term operation in thermally stressed environments.
• Compact SMD radial-can form factor: φ8 × 8.7 mm size provides high capacitance in a small board area for space-constrained designs.
• Production-ready packaging: Embossed carrier taping with moisture-proof packing streamlines automated assembly and handling.
• RoHS and lead-free reflow compatibility: Conforms to RoHS directives and supports lead-free reflow up to a 260°C peak for modern assembly processes.
