RKS1K150MCNAHJGS

The RKS1K150MCNAHJGS is a surface-mount conductive polymer aluminum electrolytic capacitor in Nichicon’s RKS series, specified at 15 µF and a rated voltage of 80 V. It is designed for general-purpose electronic power and decoupling functions where compact SMD packaging, low ESR and sustained ripple performance are required.

Key value propositions include low equivalent series resistance (40 mΩ at 100 kHz), high allowable ripple current (1.1 A at high frequency), and extended endurance (3000 hours at 125°C), enabling reliable performance in demanding thermal and electrical environments.

Key Features

• Capacitance & Tolerance — 15 µF nominal with a capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Voltage Rating — 80 V rated voltage for higher-voltage DC bus and power applications.
• Low Loss / tan δ — tanδ = 0.12 specified at 20°C, 120 Hz to indicate controlled dissipation for stable performance.
• Low ESR & High-Frequency Performance — ESR of 40 mΩ at 20°C/100 kHz and a high-frequency ripple current rating of 1.1 A (at 300 kHz), supporting efficient filtering at switching frequencies.
• Ripple Current Capability — 110 mA at 120 Hz (low-frequency) and 1.1 A at high frequency for sustained ripple handling across frequency ranges.
• Leakage Current — Specified leakage current of 100 µA, supporting predictable bias behavior after voltage application.
• Extended Endurance — Rated for 3000 hours at 125°C, enabling long-term use in elevated-temperature environments.
• Temperature Range — Operating range from −55°C to +125°C for broad environmental tolerance.
• Compact SMD Can Package — φ8 × 10 mm SMD radial can package suitable for surface-mount assembly and automated placement.
• Packaging & Production — Supplied in embossed carrier taping with moisture-proof packing; product is in mass production and RoHS compliant.

Typical Applications

• General Power Filtering — Bulk and decoupling capacitor for PCB power rails where 15 µF/80 V capacity and low ESR improve voltage stability.
• Switch-Mode Power Supplies — Output and intermediate bus filtering in power supplies that benefit from high ripple-current capability and low ESR at switching frequencies.
• Industrial and Embedded Electronics — Use in compact surface-mount designs requiring extended endurance at elevated temperatures (3000 h at 125°C).

Unique Advantages

• High-voltage capability: 80 V rating enables use on higher-voltage DC rails without changing capacitor family.
• Low ESR for efficient filtering: 40 mΩ at 100 kHz reduces dissipation and improves filtering effectiveness at high frequencies.
• Robust ripple handling: 1.1 A at high frequency and 110 mA at 120 Hz support both switching and low-frequency ripple conditions.
• Long thermal endurance: 3000 hours at 125°C provides predictable lifetime in thermally demanding applications.
• Compact SMD form factor: φ8×10 mm SMD can supports automated assembly while conserving board area.
• Manufacturing-ready packaging: Embossed carrier taping and moisture-proof packing simplify supply-chain and assembly handling.
