RKS1E101MCNAHJGS

The RKS1E101MCNAHJGS is a surface‑mount conductive polymer aluminum electrolytic capacitor in Nichicon’s RKS series. It delivers 100 µF capacitance at a 25 V rating with a compact φ8 × 10 mm can-style SMD package and is intended for general‑purpose power applications that require high ripple tolerance and long operational life.

Designed for high allowable ripple current and low equivalent series resistance, this part targets power smoothing, decoupling and high‑frequency filtering in industrial and commercial electronics where temperature endurance and reliability are required.

Key Features

• Capacitance & Voltage — 100 µF rated capacitance at 25 V provides bulk energy storage for power rails and decoupling in compact layouts.
• Low ESR / High Frequency Performance — ESR of 27 mΩ measured at 20°C / 100 kHz supports efficient high‑frequency decoupling and reduced power loss.
• High Allowable Ripple Current — Rated ripple currents of 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) enable robust AC handling across a wide frequency range.
• Loss Tangent — tan δ (DF) of 0.12 at 20°C, 120 Hz for predictable dissipation characteristics in filter and smoothing applications.
• Wide Temperature & Endurance — Operating range from −55°C to +125°C with a rated life of 3000 hours at 125°C for long‑term thermal reliability.
• Surface‑Mount Radial Can Package — Compact φ8 × 10 mm SMD radial can (L: 10 mm × D: 8 mm) for space‑efficient board integration; supplied in embossed carrier taping with moisture‑proof packing for assembly readiness.
• Leakage Current — Specified leakage current of 125 µA for predictable standby draw in restrained current budgets.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• Power Supply Smoothing — Bulk smoothing and ripple reduction on DC power rails where 100 µF and low ESR improve voltage stability.
• High‑Frequency Decoupling — Local decoupling for switching regulators and power converters leveraging the low ESR at 100 kHz and high ripple capability at 300 kHz.
• Industrial Electronics — Temperature‑tolerant energy storage for control modules and instrumentation operating across −55°C to +125°C.
• General‑Purpose Circuitry — Capacitor for general power management and filtering tasks in commercial and industrial designs.

Unique Advantages

• High Ripple Handling: 1.6 A at high frequency and 160 mA at low frequency enable sustained AC load handling for switching and pulsed loads.
• Low Dissipation Losses: 27 mΩ ESR at 100 kHz and tan δ of 0.12 reduce heat generation and improve overall power efficiency.
• Long Thermal Endurance: 3000 hours rated life at 125°C supports reliability in thermally demanding environments.
• Assembly‑Ready Packaging: Embossed carrier taping with moisture‑proof packing facilitates automated SMD line placement and storage.
• Compact SMD Can Footprint: φ8 × 10 mm radial can allows for high capacitance in a small board area.
• Regulatory Compatibility: RoHS compliance simplifies integration into designs requiring restricted‑substance conformance.
