RKS1K180MCNAHHGS

The RKS1K180MCNAHHGS is a surface‑mount conductive‑polymer aluminum solid electrolytic capacitor providing 18 µF capacitance at a rated voltage of 80 V. It combines low ESR and high allowable ripple current with a compact φ8 × 8.7 mm can‑style SMD package and embossed carrier taping for automated assembly.

Designed for general‑purpose electronic designs, the RKS1K180MCNAHHGS delivers long life and wide operating temperature capability (−55 °C to 125 °C) — offering a reliable energy reservoir and decoupling solution where elevated voltage, high ripple tolerance and thermal endurance are required.

Key Features

• Capacitance & tolerance — 18 µF with a tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Rated voltage — 80 V rated working voltage for applications requiring higher DC bus capability.
• Low ESR — 40 mΩ equivalent series resistance at 20 °C / 100 kHz, enabling efficient high‑frequency performance.
• High allowable ripple current — 110 mA at 120 Hz (low frequency) and 1.1 A at 300 kHz (high frequency) for robust ripple handling.
• Leakage current — Specified leakage current up to 100 µA after rated voltage application.
• Long endurance — Rated life of 3000 hours at 125 °C, supporting sustained high‑temperature operation.
• Wide temperature range — Operates from −55 °C to 125 °C to accommodate demanding thermal environments.
• SMD radial can package — φ8 × 8.7 mm package optimized for surface‑mount assembly; supplied in embossed carrier taping with moisture‑proof packing.
• Lead‑free reflow capable — Compatible with lead‑free reflow soldering conditions up to a 260 °C peak (per product series guidance).
• RoHS compliant — Meets RoHS directive requirements.

Typical Applications

• General‑purpose electronics — Provides bulk capacitance and decoupling in a compact SMD can for a wide range of PCB designs.
• Surface‑mount assemblies — Packaged for automated pick‑and‑place with embossed carrier taping and moisture‑proof packing.
• High‑temperature environments — Suitable where operation up to 125 °C and extended life (3000 h at 125 °C) are required.

Unique Advantages

• High voltage capability: 80 V rating enables designs with higher DC bus needs without sacrificing capacitance density.
• Low ESR at high frequency: 40 mΩ (100 kHz) contributes to improved high‑frequency stability and reduced power loss.
• Strong ripple tolerance: Separate low‑ and high‑frequency ripple current specs (110 mA @ 120 Hz, 1.1 A @ 300 kHz) support mixed‑frequency power environments.
• Extended thermal endurance: 3000 hour life at 125 °C ensures reliable performance in thermally demanding applications.
• Assembly friendly: SMD radial can with embossed carrier taping and moisture‑proof packing streamlines high‑volume manufacturing.
• Compliance focused: RoHS compliance and lead‑free reflow compatibility facilitate modern manufacturing and regulatory needs.
