RKS1D271MCNAJJGS

The RKS1D271MCNAJJGS is a surface-mount conductive polymer aluminum electrolytic capacitor from Nichicon's RKS series. It provides 270 µF capacitance at a 20 V rating in a compact φ10 × 10 mm SMD can package designed for general-purpose power decoupling and energy storage in electronic assemblies.

Designed for demanding thermal and ripple environments, this part combines low ESR (20 mΩ at 100 kHz), high allowable ripple current (up to 2 A at high frequency), and extended load life (3000 hours at 125°C) to support stable power delivery in industrial, telecommunications and embedded power modules.

Key Features

• Core Technology Conductive polymer aluminum solid electrolyte construction delivering stable capacitance and low loss under load.
• Electrical Performance 270 µF nominal capacitance with ±20% tolerance, tanδ 0.12 measured at 20°C/120 Hz, and leakage current specified at 270 µA.
• Low ESR & High Ripple Handling ESR of 20 mΩ at 100 kHz and high-frequency ripple current capability of 2 A (300 kHz) plus 200 mA at 120 Hz for robust decoupling and filtering.
• Extended Endurance Rated for 3000 hours at 125°C under rated voltage, enabling long-term operation in elevated temperature environments.
• Wide Temperature Range Operates from −55°C to +125°C to accommodate industrial and harsh-environment electronics.
• Surface-Mount Can Package Radial, can-style SMD package (φ10 × 10 mm) supplied in embossed carrier tape with moisture-proof packing for automated assembly; compatible with lead-free reflow peak temperatures up to 260°C per the series specification.
• Regulatory RoHS compliant.

Typical Applications

• Power Supply Filtering Bulk decoupling and smoothing for DC–DC converters and linear regulators where low ESR and high ripple capability improve transient response.
• Embedded Systems Energy storage and power stabilization for microcontroller-based modules and subsystems operating across wide temperature ranges.
• Industrial Electronics Power conditioning in instrumentation, control units and other industrial devices that require extended endurance at elevated temperatures.
• Telecommunications Equipment Local power decoupling in line cards, transceivers and baseband modules where high-frequency ripple handling and compact size matter.

Unique Advantages

• High Ripple Tolerance: Rated for up to 2 A at high frequency (300 kHz) and 200 mA at 120 Hz, enabling reliable filtering in high-switching-power applications.
• Low ESR for Improved Efficiency: 20 mΩ ESR at 100 kHz reduces power loss and heat generation under AC ripple, enhancing system efficiency and thermal margin.
• Extended High-Temperature Life: 3000-hour endurance at 125°C supports long-term operation in thermally challenging installations.
• Compact SMD Can Footprint: φ10 × 10 mm package balances capacitance and board space for compact power stages and modules.
• Assembly Ready Packaging: Supplied in embossed carrier tape with moisture-proof packing for automated pick-and-place and reflow processing.
• Stable Electrical Characteristics: Specified tanδ and leakage current figures provide predictable behavior for precision power designs.
