RKS1D271MCNAHGGS

The RKS1D271MCNAHGGS is a surface‑mount conductive‑polymer aluminum electrolytic capacitor delivering 270 µF at 20 V in a compact φ8 × 7.7 mm can‑SMD package. Engineered for applications demanding high capacitance, low ESR, and robust ripple handling, it combines solid polymer electrolyte construction with SMD assembly compatibility.

Key value propositions include low equivalent series resistance (30 mΩ at 100 kHz), high allowable ripple current (1.6 A at high frequency), and extended load life capability (3000 hours at 125°C), making it suitable for compact power circuitry operating across wide temperature ranges.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance with a 20 V rating and capacitance tolerance of -20% to +20% at 20°C, 120 Hz.
• Conductive‑Polymer Construction — Solid electrolyte polymer chemistry for stable performance and low loss; tan δ of 0.12 measured at 20°C, 120 Hz.
• Low ESR & High Ripple Handling — ESR of 30 mΩ at 20°C/100 kHz and high frequency ripple current of 1.6 A at 300 kHz (low frequency ripple 160 mA at 120 Hz) for improved power delivery and decoupling.
• High Temperature Endurance — Rated operating range from -55°C to +125°C with a load life of 3000 hours at 125°C, supporting demanding thermal environments.
• SMD Package & Assembly Compatibility — Radial can SMD package (φ8 × 7.7 mm) designed for surface‑mount processes; packaged in embossed carrier tape with moisture‑proof packing and compatible with lead‑free reflow profiles up to 260°C peak per soldering guidance.
• Leakage Current — Specified leakage current of 270 µA (measured under product conditions as provided).

Typical Applications

• Power Supply Decoupling — Bulk decoupling and smoothing where 270 µF capacity and low ESR reduce voltage ripple and stabilize regulators.
• Switching Power Converters — Supports converters that require high frequency ripple handling and low loss at kHz–hundreds of kHz switching frequencies thanks to 30 mΩ ESR and 1.6 A HF ripple rating.
• High‑Temperature Electronics — Systems exposed to elevated ambient temperatures benefit from the -55°C to 125°C operating range and 3000‑hour life at 125°C.

Unique Advantages

• High Capacitance in a Compact SMD Form — 270 µF in an 8 × 7.7 mm footprint enables space‑efficient designs without sacrificing bulk energy storage.
• Low ESR for Improved Power Integrity — 30 mΩ ESR at 100 kHz reduces losses and supports tighter voltage regulation in high‑current circuits.
• Robust Ripple Current Capability — 1.6 A high‑frequency ripple rating and 160 mA at 120 Hz provide headroom for demanding switching environments.
• Designed for Elevated Duty Cycles — 3000 hours at 125°C rated life supports long‑term reliability in high‑temperature applications.
• Assembly‑Friendly Packaging — Embossed carrier taping with moisture‑proof packing and compatibility with lead‑free reflow profiles simplifies automated SMT assembly.
• RoHS‑Compliant — Manufactured in accordance with RoHS requirements for lead‑free applications.
