RKS1H150MCNAFEGS

The RKS1H150MCNAFEGS is a surface mount conductive polymer aluminum solid electrolytic capacitor optimized for high-frequency and high-temperature operating environments. With a rated capacitance of 15 µF at 50 V and a compact φ6.3 × 5.8 mm can-style SMD package, it targets power electronics and board-level decoupling where low ESR, high ripple tolerance, and extended endurance are required.

Key value comes from its combination of low ESR (80 mΩ at 100 kHz), high allowable ripple current (750 mA at 300 kHz), and a guaranteed load life of 3000 hours at 125 °C, enabling reliable smoothing and decoupling on high-density power rails and compact converters.

Key Features

• Conductive polymer aluminum solid electrolytic — Solid polymer chemistry for stable electrical performance and predictable leakage characteristics.
• Capacitance and tolerance — 15 µF nominal with ±20% tolerance (measured at 120 Hz, 20 °C), suitable for board-level decoupling and smoothing functions.
• Voltage rating — 50 V rated for mid-voltage power rails and converter outputs.
• Low ESR and high-frequency performance — ESR of 80 mΩ at 100 kHz and a tan δ of 0.12 (20 °C, 120 Hz), supporting low-loss operation at high switching frequencies.
• High ripple capability — Low-frequency ripple current of 75 mA (120 Hz) and high-frequency ripple current of 750 mA (300 kHz) for robust suppression of switching noise.
• Extended high-temperature endurance — Rated life of 3000 hours at 125 °C, enabling sustained performance in elevated ambient conditions.
• Compact SMD package — φ6.3 mm diameter × 5.8 mm length can-style SMD with recommended land size 6.6 × 6.6 mm for space-constrained designs.
• Soldering and assembly — Designed for lead-free reflow soldering processes with moisture-proof packed embossed carrier taping for automated placement.
• RoHS compliant — Conforms to RoHS directive requirements.

Typical Applications

• DC–DC converter outputs — Provides output smoothing and bulk decoupling where low ESR and high ripple capability reduce voltage ripple on compact converters.
• Switch-mode power supplies — Handles high-frequency switching currents and helps suppress switching noise thanks to low ESR at 100 kHz and high allowable ripple current.
• Point-of-load decoupling — Compact can-style SMD fits tight board layouts while delivering stable capacitance and leakage behavior for local regulation stages.
• Industrial electronics — Endurance to 125 °C and 3000-hour load life supports sustained use in elevated-temperature control and power modules.

Unique Advantages

• Low-loss high-frequency performance: 80 mΩ ESR at 100 kHz and tan δ of 0.12 (20 °C, 120 Hz) minimize dissipation in switching environments.
• High ripple tolerance: 750 mA ripple current at 300 kHz supports aggressive switching topologies and high-density power stages.
• High-temperature endurance: 3000 hours at 125 °C assures long-term stability in demanding thermal environments.
• Compact SMD form factor: φ6.3 × 5.8 mm can-style package and standardized tape-and-reel packing simplify automated assembly in space-constrained designs.
• Predictable leakage performance: Specified leakage current of 100 µA (conditioning and measurement per datasheet) helps maintain reliability in bias-sensitive circuits.
• Manufacturing-ready packaging: Embossed carrier taping with moisture-proof packing supports surface-mount assembly flows.
