RKS1D151MCNAJLGS

The RKS1D151MCNAJLGS from Nichicon is a surface-mount conductive-polymer aluminum electrolytic capacitor in the RKS series. It delivers 150 µF capacitance at a 20 V rating with low equivalent series resistance and high allowable ripple current, designed for general-purpose SMD power applications.

Engineered for elevated operating ranges, this part supports an ambient temperature range of -55°C to 125°C and a rated load life of 3000 hours at 125°C, making it suited to designs that require stable capacitance and reliable performance under thermal stress.

Key Features

• Capacitance & Tolerance — 150 µF nominal with a tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Voltage Rating — Rated for 20 V operation.
• Low ESR — 20 mΩ equivalent series resistance measured at 100 kHz, supporting low-loss performance at high frequency.
• High Ripple Capability — Low-frequency ripple current of 200 mA at 120 Hz and high-frequency ripple current of 2.0 A at 300 kHz, enabling effective ripple handling across frequency ranges.
• Loss Characteristics — tanδ of 0.12 (measured at 20°C, 120 Hz) for predictable dissipation behavior.
• Leakage Current — Specified leakage current of 150 µA after application of rated voltage.
• Operating Temperature & Lifetime — Continuous operation from -55°C to 125°C with a rated endurance of 3000 hours at 125°C.
• Package & Mounting — Surface-mount can (φ10 × 12.4 mm) in embossed carrier taping with moisture-proof packing for automated assembly; lead-free reflow compatible to a 260°C peak.
• Compliance — RoHS compliant.

Typical Applications

• Power supply filtering — Use for smoothing and filtering on DC power rails where low ESR and high ripple capability are required.
• Decoupling on high-frequency rails — Effective at reducing voltage ripple in switching regulator output stages thanks to low ESR at 100 kHz and rated high-frequency ripple current.
• Bulk energy storage for SMD designs — Provides compact bulk capacitance for space-constrained surface-mount power assemblies operating up to 125°C.

Unique Advantages

• High ripple tolerance: Combined low ESR (20 mΩ @100 kHz) and 2.0 A high-frequency ripple rating enable robust ripple handling in switching power environments.
• Extended high-temperature life: Rated 3000 hours at 125°C for predictable long-term performance in thermally demanding applications.
• Compact SMD can package: φ10 × 12.4 mm SMD form factor simplifies board layout while delivering 150 µF of capacitance.
• Lead-free reflow compatibility: Designed for lead-free reflow processes with a 260°C peak soldering profile, supporting common assembly workflows.
• Manufacturing-ready packaging: Supplied in embossed carrier taping with moisture-proof packing for high-volume automated placement.
