RKS1K100MCNAFEGS

The RKS1K100MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 10 µF capacitance at an 80 V rating. Designed for general-purpose electronic designs, it delivers a compact SMD can package (φ6.3 × 5.8 mm) with high-temperature endurance and measurable high-frequency performance.

This capacitor is targeted at applications that require a high-voltage, high-temperature SMD solution with low ESR and defined ripple-current capability. Key value propositions include operation to 125 °C, a 3000‑hour life at 125 °C, low ESR at 100 kHz, and RoHS compliance.

Key Features

• Capacitance & Voltage — 10 µF rated capacitance with an 80 V maximum working voltage and tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Conductive Polymer Electrolyte — Solid conductive polymer construction for stable electrical characteristics and reduced liquid electrolyte concerns.
• High Temperature Endurance — Rated operating temperature range of −55 °C to +125 °C with a specified load life of 3000 hours at 125 °C and rated voltage.
• Low Loss / Dissipation — tanδ (loss tangent) of 0.12 measured at 20 °C, 120 Hz, supporting low-loss operation in AC and switching environments.
• Low ESR for High-Frequency Use — Equivalent Series Resistance of 120 mΩ at 20 °C, 100 kHz, enabling effective performance at high switching frequencies.
• Defined Ripple Current Capability — Low-frequency ripple current of 70 mA (120 Hz) and high-frequency ripple current of 700 mA (300 kHz), specified for design verification.
• Leakage Current — Leakage current specified at 100 µA (after conditioning), suitable for power and decoupling applications that require controlled leakage.
• SMD Can Package & Assembly — Radial, can-style SMD package (φ6.3 × 5.8 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow profiles up to 260 °C peak as specified.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• General-purpose power rails — Use on high-voltage SMD power rails where 80 V rating, low ESR at high frequency, and compact size are required.
• High-temperature electronics — Suitable for circuits that must operate up to 125 °C and require a 3000‑hour endurance at elevated temperature.
• Switching and SMPS environments — High-frequency ESR and ripple current specifications make this part appropriate for switching regulator decoupling and filtering verification.

Unique Advantages

• High-voltage SMD option: 80 V rating in a compact φ6.3 × 5.8 mm can allows designers to support higher-voltage rails without sacrificing board area.
• Thermal reliability: 3000‑hour life at 125 °C provides predictable endurance for high-temperature applications and extended field performance.
• High-frequency performance: 120 mΩ ESR at 100 kHz and a 700 mA ripple rating at 300 kHz enable effective decoupling in high-speed switching circuits.
• Controlled leakage and loss: 100 µA leakage and tanδ of 0.12 (20 °C, 120 Hz) support stable behavior in precision and power-management designs.
• Manufacturing-ready packaging: Supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow profiles to support automated SMD assembly.
