RKS1K150MCNAHHGS

The RKS1K150MCNAHHGS is a surface‑mount conductive polymer aluminum electrolytic capacitor from Nichicon’s RKS series, rated at 15 µF and 80 V. It is engineered for general‑purpose power applications that require high ripple tolerance, low ESR, and extended operation in elevated temperatures.

Key design benefits include a compact φ8 × 8.7 mm SMD can package, RoHS compliance, and a verified endurance of 3000 hours at 125°C—making it suitable for demanding industrial and power electronics environments.

Key Features

• Capacitance & Tolerance — 15 µF nominal with ±20% (–20% to +20%) tolerance at 120 Hz, 20°C for predictable decoupling and energy storage.
• Rated Voltage — 80 V rating for higher‑voltage power rails and intermediate bus applications.
• Low ESR — 40 mΩ measured at 100 kHz (20°C) to minimize I²R losses and improve high‑frequency performance.
• High Allowable Ripple Current — 110 mA at 120 Hz (low frequency) and 1.1 A at 300 kHz (high frequency) for effective smoothing under switching loads.
• Low Leakage — Leakage current specified at 100 µA (after conditioning), supporting stable long‑term performance.
• Wide Temperature & Endurance — Operating range –55°C to +125°C with a rated life of 3000 hours at 125°C for reliable operation in harsh thermal environments.
• SMD Can Package & Assembly — Radial can SMD package (φ8 × 8.7 mm) supplied in embossed carrier taping with moisture‑proof packing; compatible with lead‑free reflow up to 260°C (per series reflow guidance).
• RoHS Compliant — Meets applicable RoHS requirements as indicated in the product data.

Typical Applications

• DC‑DC Converters — Input/output smoothing and energy storage on 48 V or intermediate rails that require 80 V working voltage and low ESR.
• Power Supply Modules — Bulk decoupling and high‑frequency ripple attenuation in industrial and telecom power supplies.
• Motor Drive and Power Control — Filtering and transient suppression in power electronics subject to elevated temperatures and switching ripple.
• General Purpose Power Electronics — Robust SMD capacitor for assemblies needing long life at high ambient temperatures and high ripple capability.

Unique Advantages

• High‑voltage capability: 80 V rating lets designers use a single capacitor solution for higher‑voltage rails, reducing part count.
• High ripple handling: Specified ripple current of 1.1 A at 300 kHz and 110 mA at 120 Hz supports demanding switching supplies and reduces thermal stress.
• Low ESR for improved efficiency: 40 mΩ ESR at 100 kHz lowers conduction losses and improves regulation and stability in high‑frequency circuits.
• Extended high‑temperature life: 3000 hours at 125°C provides predictable ageing characteristics for long‑term reliability in hot environments.
• SMD can with tape packing: Embossed carrier taping and moisture‑proof packing enable automated placement and storage handling for volume production.
• Leakage control: Leakage specified at 100 µA ensures predictable standby and leakage behavior for power management applications.
