RSS0J221MCN1GS

The RSS0J221MCN1GS is a Nichicon RSS series conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount can. It delivers 220 µF at 6.3 V with low ESR and high ripple-current capability for general-purpose surface-mount applications.

Designed for board-level power smoothing and decoupling where low impedance, high-frequency performance and thermal endurance matter, this part combines a small φ6.3×5.7 mm package with a 2000-hour endurance rating at 105°C.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte design for stable electrical characteristics in a surface-mount can package.
• Capacitance and tolerance — 220 µF nominal with a tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Low dissipation factor — tanδ = 0.12 (measured at 20°C, 120 Hz) for reduced loss in AC conditions.
• Very low ESR — 25 mΩ (measured at 20°C/100 kHz), supporting low-impedance power rails and high-frequency decoupling.
• High ripple current capability — Rated for 250 mA at 120 Hz and 2.5 A at 300 kHz, with frequency coefficients that provide full rated ripple at 100 kHz and 300 kHz.
• Leakage current — 700 µA (after 2 minutes at 20°C), enabling predictable standby and bias currents.
• Thermal and life rating — Operating range -55°C to +105°C with a load life/endurance of 2000 hours at 105°C.
• Compact SMD package — φ6.3×5.7 mm case (package case: radial, can - SMD) suitable for tight board layouts; recommended land size L: 6.6 × W: 6.6 mm.
• Production-ready packaging — Embossed carrier taping with moisture-proof packing; part is in mass production and RoHS compliant.

Typical Applications

• General-purpose surface-mount circuits — Suited for PCB power networks that require a 6.3 V, 220 µF capacitor with low ESR and high ripple handling.
• High-frequency ripple environments — Designed to manage ripple currents up to 2.5 A at higher frequencies (300 kHz) while maintaining low ESR.
• Thermally demanding assemblies — Rated for continuous operation across -55°C to +105°C with a 2000-hour endurance at maximum operating temperature.

Unique Advantages

• Low ESR for improved power stability: 25 mΩ at 100 kHz reduces voltage ripple and helps maintain stable rail voltages in compact designs.
• High ripple capability across frequencies: Rated ripple of 250 mA at 120 Hz and 2.5 A at 300 kHz, with frequency coefficients supporting full ripple at 100 kHz and 300 kHz.
• Robust thermal endurance: -55°C to +105°C operating range and 2000 hours life at 105°C provide predictable long-term performance in elevated-temperature environments.
• Compact SMD footprint: φ6.3×5.7 mm can and a recommended land size of 6.6 × 6.6 mm enable space-efficient placement on densely populated PCBs.
• Production-ready packaging and compliance: Embossed carrier taping with moisture-proof packing, RoHS compliant and available in mass production quantities.
• Measurable loss characteristics: tanδ = 0.12 at 20°C/120 Hz and defined leakage current of 700 µA for predictable AC and DC behavior.
