RKS1V220MCNAHHGS

The RKS1V220MCNAHHGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 22 µF capacitance at a 35 V rating. It combines low equivalent series resistance (30 mΩ at 100 kHz) and high allowable ripple current to support compact, high-frequency power designs.

Engineered for high-temperature operation up to 125°C with a 3000 hour rated life at 125°C, this part is targeted at applications that require stable capacitance, low loss (tanδ 0.12 at 20°C/120 Hz), and robust endurance under elevated temperature and ripple stress.

Key Features

• Capacitance & Voltage: 22 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance for predictable decoupling and energy storage.
• Low ESR: 30 mΩ ESR specified at 20°C/100 kHz, enabling efficient high-frequency filtering and reduced dissipation in switching applications.
• High Ripple Current Capacity: Rated ripple currents of 160 mA at 120 Hz and 1.6 A at 300 kHz support both low- and high-frequency ripple demands.
• High-Temperature Endurance: Designed for operation from –55°C to +125°C with a rated load life of 3000 hours at 125°C, providing long-term stability in hot environments.
• Leakage & Loss: Leakage current specified at 100 µA and tanδ of 0.12 (20°C/120 Hz) for controlled leakage and dissipation.
• SMD Package & Assembly: Compact φ8 × 8.7 mm can-style SMD package supplied in embossed carrier taping and moisture-proof packing; compatible with lead-free reflow up to 260°C peak per the series soldering profile.
• Compliance: RoHS compliant, aligning with modern environmental requirements.

Typical Applications

• Power Conversion: Bulk and output filtering in DC–DC converters and switching regulators where high ripple current capability and low ESR improve efficiency and stability.
• Telecom & Networking Equipment: Decoupling and smoothing in high-density power rails that require reliable operation to 125°C and long lifecycle performance.
• Industrial Electronics: Energy storage and transient suppression in control equipment and power modules exposed to elevated ambient temperatures and continuous ripple stress.

Unique Advantages

• High ripple tolerance: The combination of low ESR (30 mΩ) and 1.6 A high-frequency ripple rating supports aggressive switching topologies with reduced thermal rise.
• Extended high-temperature life: 3000 hours at 125°C provides proven endurance for applications operating in sustained high-temperature environments.
• Compact SMD form factor: φ8 × 8.7 mm can-style SMD packaging enables space-efficient placement while supporting automated assembly with embossed carrier taping.
• Low loss and controlled leakage: tanδ of 0.12 and leakage current of 100 µA ensure predictable behavior for precision power rails and long-term reliability.
• Lead-free reflow compatibility: Designed for lead-free reflow soldering (260°C peak), simplifying integration into modern surface-mount manufacturing flows.
• RoHS compliance: Meets RoHS requirements for environmentally conscious designs.
