RKS1C151MCNAFEGS

The RKS1C151MCNAFEGS from Nichicon is a surface-mount, conductive-polymer aluminum solid electrolytic capacitor rated at 150 µF and 16 V. It delivers low ESR and defined ripple-current capability in a compact SMD radial-can package (φ6.3 × 5.8 mm).

Designed for general-purpose electronic assemblies, this part offers a wide operating temperature range and extended load-life performance, making it suitable for board-level decoupling and filtering where stable capacitance, low loss, and high temperature endurance are required.

Key Features

• Capacitance and Tolerance — 150 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C), providing predictable bulk capacitance for power and decoupling functions.
• Rated Voltage — 16 V DC rating for common low-voltage power rails.
• Conductive-Polymer Aluminum Construction — Solid electrolyte chemistry used in the RKS series for reliable performance and low loss; tangent of loss angle (tan δ) specified at 0.12 (20°C, 120 Hz).
• Low ESR — 50 mΩ ESR specified at 20°C/100 kHz, supporting lower dissipation and improved high-frequency behavior.
• Ripple Current Capability — 100 mA at 120 Hz (low frequency) and 1 A at 300 kHz (high frequency), enabling effective handling of both low- and high-frequency ripple in power circuits.
• Leakage Current — 120 µA specified, suitable for general-purpose circuit designs where controlled leakage is required.
• Extended High-Temperature Life — Rated load life of 3000 hours at 125°C, providing predictable endurance in elevated-temperature environments.
• Package and Mounting — Surface-mount radial-can package, size φ6.3 × 5.8 mm, supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Compliance — RKS series is indicated as compliant to the RoHS directive (2011/65/EU, (EU)2015/863) in the product documentation.

Typical Applications

• General-purpose electronic assemblies — Provides bulk capacitance and decoupling for a wide range of PCB-level circuits that specify a 150 µF, 16 V SMD polymer aluminum capacitor.
• Power-rail smoothing — Low ESR and defined ripple-current ratings support smoothing and stability on DC power rails in compact designs.
• High-temperature board-level designs — Suitable for applications requiring continuous operation up to 125°C with a rated load life of 3000 hours.

Unique Advantages

• Low ESR at high frequency: 50 mΩ at 100 kHz reduces I²R losses and improves high-frequency performance compared with higher-ESR options.
• Balanced ripple capability: Specified ripple current at both 120 Hz and 300 kHz supports mixed-frequency power environments.
• High-temperature endurance: 3000-hour life at 125°C provides predictable aging and reliability in elevated-temperature applications.
• Compact SMD radial-can: φ6.3 × 5.8 mm package minimizes board space while maintaining substantial capacitance for its size.
• Manufacturing-ready packaging: Supplied in embossed carrier taping with moisture-proof packing to support automated pick-and-place assembly and storage control.
• Documented leakage and loss parameters: Specified leakage current (120 µA) and tan δ (0.12 at 120 Hz, 20°C) aid in accurate thermal and stability budgeting during design.
