RKS1H150MCNAHFGS

The RKS1H150MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series. It delivers 15 µF capacitance at a 50 V rating with low ESR and designed endurance for high-temperature operation.

Engineered for SMD power applications that require high allowable ripple current and stable performance up to 125°C, this part combines low loss (tanδ) and robust leakage and life characteristics for reliable board-level energy smoothing and filtering.

Key Features

• Core Electricals  15 µF nominal capacitance with tolerance −20% to +20%, rated for 50 V operation.
• Low Loss / Stability  tanδ = 0.12 measured at 20°C, 120 Hz, providing predictable loss performance under typical test conditions.
• Low ESR  30 mΩ equivalent series resistance specified at 20°C / 100 kHz for improved high-frequency performance and reduced heat generation.
• High Ripple Capability  Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) to support demanding AC ripple environments.
• Leakage and Polarization  Polarized design with leakage current specified at 100 µA, appropriate for stable DC applications.
• Thermal Endurance  Rated operating temperature −55°C to +125°C with a load-life specification of 3000 hours at 125°C.
• SMD Package & Assembly  Compact radial can SMD style, body φ8 × 6.7 mm, supplied in embossed carrier taping with moistureproof packing and compatible with lead-free reflow profiles.
• Environmental Compliance  RoHS-compliant construction.

Typical Applications

• SMD high-ripple circuits  Suited for board-level locations that require high allowable ripple current and low ESR, supported by the part’s 1.6 A (300 kHz) HF and 160 mA (120 Hz) LF ripple ratings.
• High-temperature power modules  Intended for assemblies operating up to 125°C with a 3000-hour endurance at rated voltage, enabling stable capacitance and ESR over extended high-temperature use.
• Compact power filtering  Small φ8 × 6.7 mm SMD package provides capacitance and filtering in space-constrained designs while maintaining low ESR and controlled loss.

Unique Advantages

• Measurable high-frequency performance: ESR 30 mΩ at 100 kHz yields lower impedance at switching frequencies, improving filtering effectiveness.
• Specified ripple handling: Defined ripple current ratings at both low and high frequencies allow designers to match component selection to real-world ripple conditions.
• High-temperature durability: 3000 hours life at 125°C provides a clear, testable endurance metric for thermally aggressive designs.
• Predictable loss characteristics: tanδ specified at 20°C/120 Hz supports thermal and efficiency calculations during design validation.
• SMD-ready packaging: Embossed carrier taping and moisture-proof packing simplify automated placement and assembly workflows.
• RoHS compliance: Meets RoHS directive requirements for lead-free assemblies.
