RPS1C221MCN1GS

The RPS1C221MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can (φ8×11.7 mm). It delivers 220 µF capacitance at a 16 V rating with low equivalent series resistance and high ripple-current capability for compact power designs.

Designed for general-purpose surface-mount applications, this part targets designs that require stable capacitance across a wide temperature range and long endurance under elevated temperature operation.

Key Features

• Capacitance & tolerance — 220 µF with a tolerance of −20% to +20% (measured at 120 Hz, 20°C), suitable for bulk decoupling and energy storage in compact designs.
• Rated voltage — 16 V rated voltage providing headroom for common low-voltage power rails.
• Low ESR — ESR of 20 mΩ measured at 20°C/100 kHz, enabling improved high-frequency performance and reduced power loss.
• High ripple current — Low-frequency ripple current 370 mA at 120 Hz and high-frequency ripple current 3.7 A at 300 kHz, supporting demanding AC ripple and switching-power applications.
• Loss tangent — tanδ (DF) = 0.12 at 20°C/120 Hz, for controlled dissipation characteristics.
• Leakage current — 704 µA (specified value), consistent with conductive polymer aluminum solid electrolytic performance.
• Endurance — Rated life of 2000 hours at 105°C, for long-term operation under elevated temperatures.
• Wide operating temperature — −55°C to +105°C operating range to accommodate harsh thermal environments.
• Package and mounting — Surface-mount radial can, size φ8×11.7 mm (L: 11.7 mm × D: 8.0 mm) with recommended land size L: 8.3 × W: 8.3 mm and supplied in embossed carrier taping with moisture-proof packing.
• RoHS compliant — Compliant with RoHS requirements.
• Reflow compatibility — Series-level lead-free reflow soldering condition rated to a 260°C peak (per datasheet series information).

Typical Applications

• General-purpose electronics — Suited for surface-mount boards that require reliable bulk capacitance and stable performance across a wide temperature range.
• Power-supply filtering — Low ESR and high ripple-current capability make this capacitor appropriate for smoothing and filtering in switching power modules and regulators.
• High-frequency decoupling — ESR and ripple specifications at 100 kHz–300 kHz support applications with high-frequency switching components.

Unique Advantages

• High ripple tolerance: 3.7 A high-frequency ripple current rating and 370 mA at 120 Hz reduce stress in switching-power applications and improve thermal performance.
• Low ESR at high frequency: 20 mΩ measured at 20°C/100 kHz lowers conduction loss and enhances transient response in compact power networks.
• Compact SMD radial can: φ8×11.7 mm package provides substantial capacitance in a small footprint for space-constrained boards.
• Wide temperature and endurance: −55°C to +105°C operating range with 2000 hours endurance at 105°C supports sustained operation in thermally demanding environments.
• Manufacturing-ready packaging: Supplied in embossed carrier taping with moisture-proof packing to support automated surface-mount assembly and handling.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for electronic assemblies.
