RKS1C221MCNAJLGS

The RKS1C221MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It delivers 220 µF capacitance at a 16 V rated voltage in a compact φ10 × 12.4 mm SMD can package intended for general-purpose electronic designs.

Designed for reliable high-temperature operation, this part features a wide operating temperature range and a specified load life of 3000 hours at 125°C, providing a balance of capacitance density, low ESR and ripple-current capability for demanding power applications.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 16 V rated voltage and ±20% capacitance tolerance at 20°C, 120 Hz.
• Conductive-Polymer Construction — Solid electrolyte design for stable performance and reduced equivalent series resistance compared with traditional electrolytics.
• Low Loss (tan δ) — tanδ of 0.12 measured at 20°C, 120 Hz for predictable dissipation characteristics.
• Low ESR — ESR specified at 20 mΩ (20°C, 100 kHz) to reduce power loss and thermal rise in high-frequency applications.
• High Ripple Current Capability — Rated low-frequency ripple current of 200 mA at 120 Hz and high-frequency ripple current of 2 A at 300 kHz to support demanding power rails.
• Leakage Current — Specified leakage current of 176 µA, suitable for general-purpose electronic use.
• High-Temperature Endurance — Endurance specified as 3000 hours at 125°C to support elevated operating environments.
• Compact SMD Can Package — φ10 × 12.4 mm radial can (SMD) for space-efficient PCB implementation; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS Compliance — Series-level compliance to the RoHS directive as documented in the product datasheet.
• Mass Production Availability — Part status indicated as mass production for predictable sourcing.

Typical Applications

• General-purpose electronic designs — Suitable where a 220 µF, 16 V SMD capacitor with low ESR and rated high-temperature endurance is required.
• Power management modules — Used on power rails that benefit from high ripple-current capability and low loss at high frequency.
• Compact assemblies — Small φ10 × 12.4 mm SMD can supports space-constrained PCBs and automated assembly via embossed carrier taping.

Unique Advantages

• High ripple tolerance: 200 mA at 120 Hz and 2 A at 300 kHz ripple-current ratings support robust filtering and decoupling on power rails.
• Low ESR performance: 20 mΩ at 100 kHz minimizes I²R losses and thermal rise in high-frequency conditions.
• Extended high-temperature life: 3000 hours endurance at 125°C provides predictable long-term performance in elevated-temperature environments.
• Stable loss characteristics: tanδ of 0.12 at 20°C/120 Hz yields consistent dissipation behavior across operating conditions.
• Assembly-ready packaging: Embossed carrier taping and moisture-proof packing enable reliable pick-and-place and reflow processing (peak 260°C per datasheet reflow guidance).
• Manufacturer pedigree: Part of Nichicon's RKS series of conductive-polymer aluminum solid electrolytic capacitors, with series-level specifications documented in the datasheet.
