RKS1H150MCNAFGGS

The RKS1H150MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RKS series. It delivers 15 µF capacitance at a 50 V rating in a compact φ6.3 × 7.7 mm SMD radial-can package designed for applications that demand low ESR and high ripple-current capability.

With an operating range of −55°C to 125°C and a specified load life of 3000 hours at 125°C, this part targets designs that require stable capacitance, low loss (tanδ), and reliable performance under elevated temperature and ripple stress.

Key Features

• Capacitance & Voltage — 15 µF nominal capacitance with a rated voltage of 50 V and capacitance tolerance of −20% to +20%.
• Low ESR and High-Frequency Performance — ESR specified at 40 mΩ measured at 20°C/100 kHz, enabling effective high-frequency decoupling and lower loss in switching environments.
• High Allowable Ripple Current — Low-frequency ripple current 110 mA (120 Hz) and high-frequency ripple current 1.1 A (300 kHz) for robust handling of AC stress.
• Wide Temperature & Long Endurance — Operating temperature range −55°C to 125°C with a rated endurance of 3000 hours at 125°C for long-term high-temperature operation.
• Leakage & Loss — Leakage current specified at 100 µA and tanδ (loss tangent) 0.12 measured at 20°C, 120 Hz for predictable loss and leakage behavior.
• SMD Radial-Can Package & Reflow Compatibility — Compact φ6.3 × 7.7 mm SMD can, supplied in embossed carrier taping with moisture-proof packing; compatible with lead‑free reflow soldering conditions (260°C peak as specified).
• Regulatory — RoHS compliant.

Typical Applications

• Power conversion modules — Local energy storage and output smoothing where high ripple current and low ESR are required in a compact SMD form factor.
• High-temperature electronics — Circuits that operate or are assembled for elevated temperatures, leveraging the −55°C to 125°C range and 3000-hour endurance at 125°C.
• High-frequency decoupling — Filtering and decoupling near switching devices where low ESR at 100 kHz and strong high-frequency ripple capability improve stability.

Unique Advantages

• Designed for ripple-intensive environments: Rated ripple current of 1.1 A (300 kHz) and 110 mA (120 Hz) supports aggressive switching and AC stress without excessive heating.
• Low electrical loss: 40 mΩ ESR at 100 kHz and tanδ of 0.12 (20°C, 120 Hz) reduce power dissipation and help maintain efficiency in power-dense designs.
• High-temperature endurance: 3000 hours at 125°C provides predictable lifetime performance for long-term deployment in hot operating conditions.
• Compact SMD radial-can footprint: φ6.3 × 7.7 mm package enables high capacitance density on space-constrained PCBs while supporting standard surface-mount assembly flows.
• Manufacturing-friendly packaging: Supplied in embossed carrier taping with moisture-proof packing to support automated pick-and-place and reflow processing.
• Regulatory compliance: RoHS compliant for designs requiring restriction of hazardous substances.
