RKS1E220MCNAHFGS

The RKS1E220MCNAHFGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor with 22 µF rated capacitance at 25 V. It delivers low ESR and high allowable ripple current in a compact φ8 × 6.7 mm SMD can optimized for demanding power applications.

Designed for high-temperature endurance and reflow assembly, this capacitor targets power supply decoupling and high-frequency power circuits where low loss, thermal robustness, and reliable long-term operation are required.

Key Features

• Capacitance & Rating — 22 µF nominal capacitance with ±20% tolerance at 20°C, rated for 25 V operation.
• Low Loss & ESR — tanδ (DF) 0.12 (20°C, 120 Hz) and ESR 30 mΩ measured at 20°C/100 kHz, supporting efficient high-frequency filtering.
• High Ripple Current Capability — 160 mA at 120 Hz (low-frequency) and 1.6 A at 300 kHz (high-frequency), enabling robust handling of switching ripple.
• Leakage Current — Leakage current specified at 100 µA, supporting predictable standby and quiescent behavior.
• Thermal & Endurance Performance — Rated operating range −55°C to +125°C with a load life of 3000 hours at 125°C.
• Reflow-Compatible SMD Package — φ8 × 6.7 mm radial can SMD package with embossed carrier taping and moisture-proof packing; compatible with lead-free reflow soldering up to 260°C peak per datasheet conditions.
• RoHS Compliance — Product series is stated as compliant to the RoHS directive (2011/65/EU, (EU)2015/863) in the series documentation.

Typical Applications

• Power-supply decoupling and bulk smoothing — Low ESR and high ripple current make this capacitor suitable for decoupling and bulk energy storage on DC power rails.
• DC–DC converter output filtering — High-frequency ripple capability and low loss support stable output filtering in switching regulators and converters.
• Power modules and industrial electronics — Wide operating temperature and extended 3000-hour life at 125°C suit high-temperature and continuous-load environments.

Unique Advantages

• Low ESR for high-frequency performance: 30 mΩ (100 kHz) ESR reduces conduction losses and improves filtering effectiveness in switching applications.
• High allowable ripple current: 1.6 A at 300 kHz and 160 mA at 120 Hz enable reliable handling of both high-frequency switching ripple and lower-frequency variations.
• Extended high-temperature endurance: 3000 hours at 125°C supports long-term reliability in thermally demanding systems.
• Reflow-friendly SMD format: φ8 × 6.7 mm SMD can with embossed carrier taping and moisture-proof packing streamlines automated assembly and inventory handling.
• Predictable leakage and dissipation: Specified leakage current (100 µA) and tanδ (0.12) aid designers in power-budgeting and thermal management.
