RKS1C561MCNAHHGS

The RKS1C561MCNAHHGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 560 µF capacitance at a 16 V rating. Designed for general-purpose SMD power applications, it combines high capacitance in a compact φ8 × 8.7 mm can-style SMD package suitable for automated assembly.

Its value proposition centers on high allowable ripple current, low ESR at high frequency, and extended endurance — making it a strong choice where stable filtering and decoupling are required under elevated temperature and long-life conditions.

Key Features

• Capacitance & Tolerance — 560 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), providing predictable bulk energy storage for power rails.
• Rated Voltage — 16 V rated voltage suitable for many low-voltage power-supply and DC-DC converter designs.
• Low ESR at High Frequency — ESR of 30 mΩ measured at 20°C and 100 kHz, supporting effective high-frequency decoupling and reduced power loss in switching applications.
• High Allowable Ripple Current — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency), enabling robust handling of switching and ripple currents in compact SMD layouts.
• Wide Temperature & Long Life — Operating range from −55°C to +125°C with an endurance rating of 3000 hours at 125°C, delivering extended operational stability in thermally demanding environments.
• Leakage & Loss Characteristics — Leakage current specified at 448 µA and tan δ (loss tangent) of 0.12 (measured at 20°C, 120 Hz), enabling designers to budget leakage and dissipation accurately.
• SMD Package & Assembly — Radial can SMD package (φ8 × 8.7 mm) supplied in embossed carrier taping with moisture-proof packing for pick-and-place compatibility and controlled storage.
• Environmental Compliance — RoHS compliant as specified, supporting regulatory requirements for lead-free assemblies.

Typical Applications

• General-purpose electronics — Bulk filtering and decoupling where a high-capacitance SMD solution is required for compact power subsystems.
• Switch-mode power supplies — Output filtering and ripple smoothing in DC-DC converters, benefiting from the part’s low ESR and high-frequency ripple handling.
• High-frequency power circuits — Decoupling in circuits with fast switching where 100 kHz ESR performance and 300 kHz ripple capability improve stability and transient response.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 160 mA (120 Hz) and 1.6 A (300 kHz) reduce the need for parallel components to handle AC stress.
• Low high-frequency ESR: 30 mΩ at 100 kHz lowers I²R losses and helps maintain voltage stability in fast switching environments.
• Compact SMD form factor: φ8 × 8.7 mm radial can-style package provides high capacitance density for space-constrained boards while remaining compatible with automated assembly and moisture-proof packaging.
• Extended high-temperature life: 3000 hours endurance at 125°C supports long-term reliability in elevated-temperature applications.
• Predictable leakage and loss: Specified leakage current (448 µA) and tan δ (0.12) allow accurate thermal and power-loss budgeting in system designs.
