RKS1E151MCNAHHGS

The RKS1E151MCNAHHGS is a Nichicon RKS-series conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial-can package. It delivers 150 µF at 25 V with low equivalent series resistance and rated ripple performance for SMD applications.

Designed for high-frequency and high-temperature environments, this part offers low ESR (30 mΩ at 100 kHz), high allowable ripple current (160 mA at 120 Hz and 1.6 A at 300 kHz), and a rated operating range of −55 °C to 125 °C with a rated life of 3000 hours at 125 °C.

Key Features

• Electrolyte / Core — Conductive polymer aluminum solid electrolyte provides stable capacitance and low ESR in an SMD radial-can form factor.
• Capacitance & Voltage — 150 µF nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20%.
• Low ESR & High-Frequency Performance — ESR of 30 mΩ measured at 100 kHz and specified high-frequency ripple current of 1.6 A at 300 kHz for demanding HF decoupling.
• Ripple Current Capability — Low-frequency ripple current rating of 160 mA at 120 Hz and high-frequency rating of 1.6 A at 300 kHz to support power-stage filtering and smoothing.
• Thermal & Endurance — Rated for −55 °C to 125 °C and a load life of 3000 hours at 125 °C, supporting extended operation in elevated temperature environments.
• Assembly & Packaging — SMD radial-can package (φ8 × 8.7 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering profiles up to 260 °C peak.
• Leakage & Dissipation — Specified leakage current and tan δ (0.12 at 20 °C, 120 Hz) for predictable power loss and standby behavior.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• SMD circuits requiring high ripple tolerance — Suited for surface-mount designs where high allowable ripple current and low ESR are needed.
• High-frequency decoupling — Low ESR at 100 kHz and specified high-frequency ripple current make it appropriate for HF decoupling and filtering functions.
• Elevated-temperature electronics — Rated for continuous operation up to 125 °C with a 3000-hour load life for long-term performance in hot environments.

Unique Advantages

• High ripple-current capability: 1.6 A at 300 kHz and 160 mA at 120 Hz provide margin for demanding ripple and transient currents.
• Low ESR for HF performance: 30 mΩ at 100 kHz reduces loss and improves filtering effectiveness at high switching frequencies.
• Robust thermal endurance: 3000 hour life at 125 °C supports reliability in thermally stressed assemblies.
• SMD-ready package and soldering compatibility: Embossed carrier taping and moisture-proof packing plus reflow compatibility (260 °C peak) streamline automated assembly.
• Predictable electrical behavior: Specified tan δ, leakage current, and capacitance tolerance enable straightforward design margining and verification.
