RKS1E151MCNAHFGS

The RKS1E151MCNAHFGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 150 µF at 25 V in a compact φ8 × 6.7 mm can-style SMD package. It combines low ESR, high allowable ripple current and extended high-temperature endurance for power-dense surface-mount assemblies.

Designed for applications that demand stable filtering and energy hold under elevated temperature and high-frequency stress, this part delivers measurable performance advantages where ripple tolerance, long life at temperature, and compact PCB footprint are priorities.

Key Features

• Capacitance & Voltage: 150 µF rated capacitance with a rated voltage of 25 V and a tolerance of -20% to 20% for predictable bulk energy storage.
• Conductive Polymer Electrolyte: Solid conductive polymer construction for improved stability and performance compared with traditional wet electrolytes.
• Low ESR & High Frequency Ripple Handling: ESR of 30 mΩ (measured at 100 kHz, 20°C) and a high-frequency ripple current rating of 1.6 A (at 300 kHz), enabling efficient high-frequency decoupling and reduced power dissipation.
• Low-Frequency Ripple Capability: 160 mA ripple current at 120 Hz for robust performance in lower-frequency smoothing applications.
• High-Temperature Endurance: Rated operating range from -55°C to 125°C with a load-life specification of 3000 hours at 125°C to support long-term operation in hot environments.
• Leakage & Losses: Specified leakage current of 187 µA and tan δ of 0.12 (measured at 20°C, 120 Hz), supporting reliable passive behavior in DC circuits.
• SMD Can Package & Reflow Compatibility: φ8 × 6.7 mm can-style SMD package with embossed carrier taping and moisture-proof packing; compatible with lead-free reflow soldering profiles specified for the series.
• Production Ready: Mass production status and RoHS compliance for volume deployment and regulatory conformity.

Typical Applications

• Power supply filtering and decoupling: Low ESR and high ripple current ratings make this capacitor well suited to smoothing outputs of switching regulators and reducing voltage ripple in DC power rails.
• DC-DC converter output stages: Compact SMD can construction with high-frequency ripple capability supports bulk and hold functions on converter outputs where board space is limited.
• Industrial electronics: Wide operating temperature (-55°C to 125°C) and 3000-hour life at 125°C support robust operation in industrial power modules and control equipment.

Unique Advantages

• High ripple tolerance: 1.6 A at 300 kHz and 160 mA at 120 Hz enable reliable handling of both high-frequency and low-frequency ripple loads, reducing thermal stress on the capacitor.
• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz minimizes I²R losses and supports tighter voltage regulation in power systems.
• Extended high-temperature life: 3000 hours at 125°C provides predictable endurance for designs exposed to sustained high temperatures.
• Compact SMD form factor: φ8 × 6.7 mm can-style package offers a small PCB footprint for space-constrained designs while retaining high capacitance.
• Manufacturing and supply readiness: Embossed carrier taping with moisture-proof packing and mass production status simplify PCB assembly and procurement.
• Regulatory compliance: RoHS-compliant construction supports use in regions requiring restricted substance conformity.
