RKS1D151MCNAFGGS

The RKS1D151MCNAFGGS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It delivers 150 µF at 20 V with a compact φ6.3 × 7.7 mm footprint and is optimized for applications requiring high allowable ripple current and low ESR.

Designed for demanding thermal and high-frequency environments, this part provides verified endurance of 3000 hours at 125°C and RoHS-compliant construction for modern assembly processes.

Key Features

• Capacitance & Voltage — 150 µF rated at 20 V with ±20% tolerance, suitable where a mid-range capacitance in an SMD format is required.
• Conductive-Polymer Construction — Solid electrolyte conductive polymer architecture for stable performance and low equivalent series resistance.
• Low ESR & High-Frequency Performance — ESR of 30 mΩ measured at 20°C/100 kHz and a high-frequency ripple current rating of 1.4 A at 300 kHz, supporting high-speed switching environments.
• Ripple Current Capability — Low-frequency ripple current 140 mA at 120 Hz and high-frequency ripple current 1.4 A at 300 kHz, enabling robust decoupling under varying ripple conditions.
• Thermal Endurance — Rated operating temperature range −55°C to +125°C with an endurance (load life) of 3000 hours at 125°C.
• SMD Radial-Can Package — Compact φ6.3 × 7.7 mm can with surface-mount land recommendation 6.6 × 6.6 mm and embossed carrier taping with moisture-proof packing for automated assembly.
• Leakage Current — Specified leakage current of 150 µA, measured after rated voltage application conditions.
• RoHS Compliant — Meets RoHS requirements for restricted substances in electronic components.

Typical Applications

• SMD designs requiring high ripple current — Suitable where high allowable ripple current and low ESR are primary needs, as indicated by the specified ripple current and ESR values.
• High-frequency circuits — ESR specified at 100 kHz and a high-frequency ripple current rating at 300 kHz make this capacitor applicable to high-frequency supply decoupling where those parameters are critical.
• High-temperature operating environments — With an operating range of −55°C to 125°C and 3000-hour endurance at 125°C, the part is applicable where elevated temperature reliability is required.

Unique Advantages

• Low ESR for reduced losses: 30 mΩ ESR at 100 kHz lowers AC losses and supports efficient high-frequency operation.
• High allowable ripple current: 1.4 A at 300 kHz (high frequency) and 140 mA at 120 Hz (low frequency) provide flexibility across switching regimes.
• Thermal robustness: Rated to −55°C to +125°C with a 3000-hour load life at 125°C, offering predictable long-term performance under elevated temperatures.
• SMD-ready packaging: Embossed carrier taping and moisture-proof packing support automated assembly and lead-free reflow processes up to specified profiles.
• Compact radial-can footprint: φ6.3 × 7.7 mm size and recommended land pattern (6.6 × 6.6 mm) enable high-density board placement.
• Regulatory compliance: RoHS conformity for use in assemblies requiring restricted-substance compliance.
