RKS1C221MCNAHGGS

The RKS1C221MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor featuring 220 µF nominal capacitance and a 16 V rated voltage. It is a polar SMD can-style capacitor engineered for general-purpose electronic designs that require high capacitance in a compact footprint.

Designed for demanding thermal and ripple environments, this part delivers a 3000-hour rated life at 125°C, a wide operating temperature range from −55°C to 125°C, and measurable high-frequency performance suitable for designs that need stable capacitance and controlled ESR across temperature.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of −20% to +20% at 20°C, 120 Hz.
• Low Loss Angle (tan δ): tanδ specified at 0.12 under 20°C, 120 Hz measurement conditions for predictable dissipation characteristics.
• Low ESR: Equivalent series resistance of 30 mΩ measured at 20°C/100 kHz, supporting stable high-frequency behavior.
• High Ripple Current Handling: Low-frequency ripple current of 160 mA at 120 Hz and high-frequency ripple current of 1.6 A at 300 kHz, enabling effective smoothing and decoupling in power circuits.
• Leakage Current: Specified leakage current of 176 µA (measured per part data), suitable for many general-purpose applications.
• Temperature & Endurance: Operating range from −55°C to 125°C with a rated life of 3000 hours at 125°C for long-term thermal reliability.
• Package & Mounting: Radial SMD can (φ8 × 7.7 mm) packaged for surface-mount assembly; supplied in embossed carrier taping with moisture-proof packing.
• Manufacturing Readiness: SMD type compatible with lead-free reflow soldering up to a 260°C peak, per manufacturer soldering conditions.
• RoHS Compliance: Series documentation indicates compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply decoupling: 220 µF capacitance combined with 1.6 A high-frequency ripple capability supports bulk decoupling and local energy storage on DC rails.
• DC–DC converters and POL modules: Low ESR (30 mΩ at 100 kHz) helps reduce switching losses and maintain stable output under high-frequency loading.
• Industrial and general-purpose electronics: Wide −55°C to 125°C operating range and 3000-hour life at 125°C suit equipment exposed to broad thermal conditions.

Unique Advantages

• Compact high-capacitance SMD solution: 220 µF in a φ8 × 7.7 mm can-style SMD package enables space-efficient board layouts.
• Measured high-frequency performance: 30 mΩ ESR at 100 kHz and 1.6 A ripple current at 300 kHz provide verifiable attenuation for switching noise and fast transients.
• Extended high-temperature endurance: 3000 hours rated life at 125°C gives designers a quantifiable reliability baseline for thermal stress applications.
• Predictable loss characteristics: Specified tanδ of 0.12 at 20°C/120 Hz supports thermal and dissipation calculations in power designs.
• Assembly-friendly packaging: Embossed carrier taping with moisture-proof packing and compatibility with 260°C peak lead-free reflow simplify automated placement and soldering.
