RKS1J220MCNAHFGS

The RKS1J220MCNAHFGS is a Nichicon RKS series conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount radial can. It offers 22 µF capacitance at a 63 V rating with low ESR and specified high-frequency ripple capability for demanding power applications.

Designed for elevated-temperature operation and long-term endurance, this SMD capacitor suits designs that require stable decoupling and bulk filtering under high-frequency ripple and extended high-temperature stress.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a rated voltage of 63 V and capacitance tolerance of -20% to +20%.
• Low ESR & High Ripple Capability — ESR specified at 40 mΩ (20°C, 100 kHz) with ripple current ratings of 110 mA at 120 Hz and 1.1 A at 300 kHz, supporting high-frequency power applications.
• Thermal Performance & Endurance — Rated for operation from -55°C to 125°C with a rated load life of 3000 hours at 125°C.
• Leakage & Loss — Leakage current specified at 100 µA and tangent of loss angle (tan δ) of 0.12 (20°C, 120 Hz), enabling predictable behavior in bias and decoupling circuits.
• Package & Assembly — Compact φ8 × 6.7 mm (diameter × length) radial SMD can; supplied in embossed carrier tape with moisture-proof packing and compatible with lead-free reflow soldering up to a 260°C peak as specified in the series datasheet.
• Polarized Design — Polarized electrolytic construction appropriate for DC decoupling and bulk storage applications.
• RoHS Compliant — Meets RoHS requirements as stated in the product data.

Typical Applications

• Power-supply decoupling — Low ESR and high ripple current capability make this capacitor suitable for smoothing and decoupling in power rails.
• Switching regulator output filtering — High-frequency ripple rating and 100 kHz ESR specification support use on switching regulator outputs and converter stages.
• High-temperature electronics — Specified operation to 125°C and a 3000-hour endurance at that temperature enable use in thermally demanding systems.
• Compact SMD assemblies — Small φ8 × 6.7 mm SMD can and tape packaging simplify automated placement in space-constrained boards.

Unique Advantages

• High ripple handling: 1.1 A allowed at 300 kHz and 110 mA at 120 Hz provide margin for designs with significant AC stress on capacitors.
• Predictable high-frequency performance: ESR specified at 100 kHz (40 mΩ) and tan δ defined at 120 Hz help engineers assess stability and loss across frequency ranges.
• Extended high-temperature life: 3000 hours endurance at 125°C supports reliability in elevated-temperature applications and long field life.
• Reflow-compatible packaging: Embossed carrier taping with moisture-proof packing and datasheet-defined reflow profile (260°C peak) facilitate automated assembly and handling.
• Compact footprint: φ8 × 6.7 mm dimensions deliver high capacitance in a small SMD can for dense power boards.

Why Choose RKS1J220MCNAHFGS?

RKS1J220MCNAHFGS combines conductive-polymer aluminum construction with low ESR and robust ripple-current ratings to deliver stable decoupling and bulk capacitance in compact SMD form. Its wide operating temperature range (−55°C to 125°C) and 3000-hour life at 125°C make it well suited for designs that must tolerate sustained thermal stress without sacrificing filtering performance.

This part is ideal for engineers specifying capacitors for high-frequency switching outputs, power-distribution decoupling, and compact assemblies where space, thermal endurance, and predictable ESR/ripple behavior are critical. RoHS compliance and tape-and-reel packaging simplify supply-chain and assembly integration.
