RKS1J150MCNAHFGS

The RKS1J150MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 15 µF capacitance at a 63 V rating. It combines low equivalent series resistance and high allowable ripple current to support board-level power filtering in compact SMD assemblies.

Designed for elevated-temperature operation, this part delivers a 3000-hour load life at 125 °C and a wide operating range from −55 °C to 125 °C, making it suitable for applications that require long-term stability under thermal stress.

Key Features

• Capacitance & Voltage — 15 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20%.
• Low Loss Angle (tan δ) — tan δ of 0.12 measured at 20 °C, 120 Hz, supporting effective AC performance.
• Low ESR — Equivalent series resistance of 40 mΩ measured at 20 °C and 100 kHz to reduce dissipation and voltage ripple at high frequency.
• High Ripple Current Capability — Low-frequency ripple current of 110 mA at 120 Hz and high-frequency ripple current of 1.1 A at 300 kHz for demanding switching environments.
• Leakage Current — Specified leakage current up to 100 µA after standard conditioning.
• High-Temperature Endurance — Load life specification of 3000 hours at 125 °C under rated voltage.
• Thermal and Soldering Robustness — SMD type with lead-free reflow soldering correspondence up to a 260 °C peak; reflow up to two times when peak temperature ≤ 260 °C as specified.
• Compact SMD Can — Radial can SMD package with dimensions φ8 × 6.7 mm and surface-mount land size 8.3 × 8.3 mm for board-level integration.
• Packaging for Production — Supplied in embossed carrier taping with moisture-proof packing and listed as mass production status.
• RoHS Compliance — Compliant with RoHS requirements.

Typical Applications

• Power modules and DC–DC converters — Low ESR and 1.1 A HF ripple capability support high-frequency output filtering in compact power stages.
• Point-of-load decoupling — 15 µF capacitance and low loss angle make it suitable for decoupling near switching regulators and semiconductor drivers.
• High-temperature electronics — Rated endurance of 3000 hours at 125 °C and a −55 °C to 125 °C operating range for sustained performance in hot environments.
• Space-constrained SMD assemblies — φ8 × 6.7 mm can provides usable capacitance in a compact board footprint for dense layouts.

Unique Advantages

• Low ESR for efficient filtering: 40 mΩ at 100 kHz minimizes resistive losses and helps maintain stable voltage under high-frequency switching.
• High allowable ripple current: 1.1 A at 300 kHz supports aggressive switching workloads and reduces the need for multiple parallel devices.
• Proven high-temperature endurance: 3000-hour life at 125 °C provides predictable long-term behavior in thermal stress environments.
• SMD reflow compatibility: Lead-free reflow correspondence up to 260 °C enables standard surface-mount assembly processes.
• Production-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated placement and storage.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements.
