RKS1H560MCNAHHGS

The RKS1H560MCNAHHGS from Nichicon is a surface-mount conductive-polymer aluminum electrolytic capacitor offering 56 µF capacitance at 50 V. It combines low ESR and high allowable ripple current with a long rated life at elevated temperature, making it suitable where compact bulk and high-temperature endurance are required.

Designed for assembly on modern surface-mount production lines, this Radial Can SMD device supports lead-free reflow and comes in embossed carrier taping with moisture-proof packing for integrated manufacturing workflows.

Key Features

• Electrical Performance — 56 µF nominal capacitance with ±20% tolerance and tanδ of 0.12 (measured at 20°C, 120 Hz), providing predictable impedance behavior for filtering and decoupling.
• Low ESR & High-Frequency Performance — ESR of 30 mΩ at 20°C/100 kHz and a high-frequency ripple current rating of 1.6 A (300 kHz), enabling effective high-frequency smoothing and reduced heat generation under dynamic loads.
• Ripple Current Handling — Low-frequency ripple current rating of 160 mA at 120 Hz supports bulk filtering under mains-related ripple conditions.
• Leakage & Polarization — Polarized design with leakage current specified at 140 µA, suitable for polarized bulk and decoupling roles where controlled leakage is required.
• Thermal & Reliability — Rated operating temperature from −55°C to +125°C with an endurance (load life) of 3000 hours at 125°C, offering stability in high-temperature environments.
• Mounting & Packaging — Surface-mount radial can package, dimensions φ8 × 8.7 mm, with recommended land size 8.3 × 8.3 mm; supplied in embossed carrier taping and moisture-proof packing for SMT assembly.
• Assembly Compatibility — SMD lead-free reflow capable with peak-temperature correspondence to 260°C per the series specification for reflow processes.
• Compliance — RoHS compliant for environmental regulatory requirements.

Typical Applications

• Power rail decoupling — Low ESR (30 mΩ at 100 kHz) and 56 µF capacitance provide effective decoupling and smoothing on board-level power rails where ripple reduction is needed.
• Bulk board-level filtering — 140 µA leakage and 160 mA low-frequency ripple rating make the capacitor suitable for board bulk filtering tasks that require stable leakage characteristics.
• High-temperature electronics — 3000-hour endurance at 125°C and an operating range of −55°C to +125°C support applications exposed to sustained elevated temperatures.
• High-frequency power handling — 1.6 A ripple current rating at 300 kHz and low ESR support high-frequency smoothing demands in power conversion and high-speed switching environments.

Unique Advantages

• Low ESR for efficient HF smoothing: 30 mΩ ESR at 100 kHz reduces impedance at switching frequencies, improving voltage stability under transient loads.
• High ripple-current capability: 1.6 A at 300 kHz enables handling of significant AC ripple without excessive self-heating.
• High-temperature endurance: Rated 3000 hours at 125°C for sustained reliability in thermally demanding designs.
• SMT-ready packaging: Radial can SMD in embossed carrier taping with moisture-proof packing simplifies automated assembly and storage.
• Lead-free reflow compatible: Supports lead-free reflow soldering up to a 260°C peak, aligning with modern assembly processes.
• RoHS compliant: Meets environmental restrictions for restricted substances.
