RKS1D561MCNAJLGS

The RKS1D561MCNAJLGS from Nichicon is a surface-mount conductive polymer aluminum electrolytic capacitor offering 560 µF capacitance at 20 V in a compact φ10 × 12.4 mm can-style SMD package. Designed for general-purpose electronic designs, it delivers high capacitance, low equivalent series resistance, and extended high-temperature endurance for reliable power conditioning in space-constrained boards.

Key value comes from a combination of low ESR (20 mΩ at 100 kHz), high allowable ripple current (up to 2.0 A at high frequency), and a rated life of 3000 hours at 125°C, with RoHS compliance and moisture-proof embossed carrier taping for production-ready assembly.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a rated voltage of 20 V and tolerance of −20% to +20% for predictable bulk energy storage.
• Low ESR — 20 mΩ equivalent series resistance measured at 100 kHz (20°C), enabling efficient high-frequency performance.
• High Ripple Current — 200 mA at 120 Hz (low frequency) and 2.0 A at high frequency, supporting demanding ripple-handling in power rails.
• Thermal Endurance — Rated operating range −55°C to +125°C with a rated lifetime of 3000 hours at 125°C for sustained operation in elevated-temperature environments.
• Loss Characteristics — tanδ (loss tangent) of 0.12 measured at 20°C, 120 Hz, indicating stable dielectric loss behavior.
• SMD Can Package — Radial can-style SMD (φ10 × 12.4 mm) optimized for surface-mount assembly and available in embossed carrier taping with moisture-proof packing for automated handling.
• Leakage Current — Specified leakage current of 560 µA after application of rated voltage.
• Assembly Compatibility — Series datasheet indicates compatibility with lead-free reflow soldering conditions up to a 260°C peak.

Typical Applications

• General-Purpose Power Filtering — Bulk decoupling and rail smoothing where high capacitance and low ESR reduce ripple and improve voltage stability.
• SMD Power Modules — Surface-mount power stages and supply modules that require compact, high-capacitance components with strong high-frequency ripple capability.
• Embedded Systems — Board-level energy storage in compact embedded designs operating across a wide temperature range (−55°C to +125°C).

Unique Advantages

• High Capacitance in a Small Footprint: 560 µF in a φ10 × 12.4 mm SMD can delivers significant bulk capacitance for space-constrained PCB layouts.
• Low ESR for Improved Efficiency: 20 mΩ ESR at 100 kHz reduces losses and supports stable performance at higher switching frequencies.
• Strong Ripple Handling: High-frequency ripple current rating of 2.0 A enables use in demanding power conversion and filtering roles.
• Extended High-Temperature Life: 3000 hours at 125°C gives designers confidence in long-term reliability under elevated operating temperatures.
• Production-Ready Packaging: Embossed carrier taping with moisture-proof packing facilitates reliable automated placement and storage.
• RoHS Compliant: Conforms to RoHS requirements, supporting regulatory compliance in lead-free assembly environments.
