RKS1C101MCNAHJGS

The RKS1C101MCNAHJGS is a surface-mount conductive-polymer aluminum electrolytic capacitor in Nichicon's RKS series. It delivers 100 µF capacitance at 16 V with low ESR and high allowable ripple current, optimized for general-purpose power-supply and decoupling tasks in compact board-level designs.

Designed for reliability across a wide temperature range (‑55°C to 125°C) and a rated life of 3000 hours at 125°C, this SMD can supports applications that require sustained performance under thermal stress and high-frequency switching conditions.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 16 V and tolerance of ±20% (‑20%~20%).
• Conductive-Polymer Construction — Solid polymer electrolyte provides stable electrical characteristics suited to high-frequency operation and long life.
• Low ESR — ESR of 25 mΩ measured at 20°C, 100 kHz, supporting reduced loss and improved efficiency in high-frequency circuits.
• High Ripple Current Capability — Low-frequency ripple current of 170 mA (120 Hz) and high-frequency ripple current of 1.7 A (300 kHz) for switching regulator and decoupling applications.
• Wide Temperature & Endurance — Operating range from ‑55°C to 125°C with a load life of 3000 hours at 125°C, ensuring durability in thermally demanding environments.
• Leakage & Dissipation — Leakage current specified at 100 µA and tan δ (DF) of 0.12 measured at 20°C, 120 Hz, enabling predictable loss and standby behavior.
• SMD Package & Assembly — Radial can SMD package (φ8 × 10 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead‑free reflow up to 260°C peak per series specification.
• RoHS Compliant — Meets applicable RoHS requirements as stated in the product data.

Typical Applications

• Power-rail decoupling — Stabilizes DC rails and suppresses switching noise using low ESR (25 mΩ) and high-frequency ripple current capability (1.7 A).
• Switching regulator output filtering — Suited for synchronous buck and boost regulator outputs where sustained ripple current and stable capacitance over temperature are required.
• General-purpose embedded electronics — Provides bulk and decoupling capacitance for compact SMD designs that require reliable operation from ‑55°C to 125°C.

Unique Advantages

• High ripple tolerance: The combination of 1.7 A high-frequency ripple current rating and 25 mΩ ESR reduces voltage ripple and thermal stress on the capacitor in switching applications.
• Extended high-temperature life: 3000 hours endurance at 125°C offers predictable long-term performance for thermally stressed boards and power stages.
• Stable frequency performance: Conductive-polymer construction and a tan δ of 0.12 (20°C, 120 Hz) provide consistent dissipation characteristics for AC and ripple conditions.
• SMD-friendly packaging: Supplied in embossed carrier tape with moisture-proof packing and compatible with lead-free reflow up to 260°C, simplifying automated assembly and inventory handling.
• Low leakage: Specified leakage current (100 µA) enables predictable standby and bias behavior in low-current designs.
