RKS1K8R2MCNAHFGS

The RKS1K8R2MCNAHFGS is a surface‑mount conductive polymer aluminum solid electrolytic capacitor designed for high‑voltage, high‑frequency power applications. With an 8.2 µF capacitance at an 80 V rating and a wide operating temperature range, it addresses demanding system requirements where low ESR, high ripple handling and long life are required.

This part targets industrial and telecom power systems, DC‑DC converter outputs and other general‑purpose power applications that benefit from compact SMD packaging, low loss (tanδ) and extended endurance at elevated temperatures.

Key Features

• Capacitance & Voltage — 8.2 µF capacitance with an 80 V rated voltage, specified tolerance −20% to +20%.
• Conductive polymer construction — Solid electrolyte construction for stable electrical performance and defined leakage characteristics (leakage current specified at 100 µA).
• Low loss / tanδ — tanδ of 0.12 measured at 20°C, 120 Hz for reduced dissipation in AC environments.
• Low ESR — ESR of 40 mΩ measured at 20°C, 100 kHz to support efficient high‑frequency decoupling and power delivery.
• High ripple capability — Rated low‑frequency ripple 110 mA at 120 Hz and high‑frequency ripple 1.1 A at 300 kHz to handle switching and ripple currents.
• Extended endurance — Load life of 3000 hours at 125°C for long‑term reliability under elevated temperature stress.
• Wide temperature range — Operates from −55°C to +125°C for harsh environments.
• SMD can package — Compact radial can SMD: diameter φ8 × length 6.7 mm; supplied in embossed carrier taping with moisture‑proof packing for automated placement.

Typical Applications

• Power supply output smoothing — Acts as a low‑ESR bulk decoupling capacitor at DC‑DC converter outputs for stable voltage delivery under load.
• Switching regulator support — Handles high‑frequency ripple and transient currents in buck/boost converters and point‑of‑load modules.
• Industrial power electronics — Used in control and power modules where extended temperature range and long endurance at 125°C are required.
• Telecom and network equipment — Provides stable capacitance and low loss in high‑frequency power lines and filtering networks.

Unique Advantages

• High voltage capability: 80 V rating enables use in higher‑rail power stages without series stacking.
• Low ESR and low tanδ: 40 mΩ ESR at 100 kHz and tanδ 0.12 at 120 Hz reduce losses and improve regulator efficiency and transient response.
• Robust ripple handling: Specified ripple currents (110 mA at 120 Hz, 1.1 A at 300 kHz) support both low‑ and high‑frequency switching environments.
• Long life at elevated temperature: 3000 hours at 125°C offers designers predictable endurance for high‑temperature applications.
• Compact SMD can format: φ8 × 6.7 mm size and embossed carrier taping enable automated assembly in dense layouts.
• Predictable leakage behavior: Leakage current specified at 100 µA for consistent bias performance after voltage application.
