RPS1A271MCN1GS

The RPS1A271MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount can package, delivering 270 µF capacitance at a 10 V rating. Designed for general-purpose electronic applications, it combines low ESR and high ripple-current capability in a compact φ10 × 7.7 mm footprint.

Manufactured by Nichicon and available in mass production, this part targets engineers building compact power systems and surface-mount assemblies that require reliable decoupling and bulk capacitance across a wide operating temperature range.

Key Features

• Capacitance & Voltage: 270 µF rated capacitance at 10 V, with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Conductive-Polymer Construction: Solid conductive polymer aluminum dielectric for stable performance and reduced ESR compared with traditional electrolytic types.
• Low ESR: ESR of 25 mΩ measured at 20°C/100 kHz, supporting high-frequency performance and efficient power delivery.
• High Ripple Current Capability: Low-frequency ripple current 350 mA (120 Hz) and high-frequency ripple current 3.5 A (300 kHz), with frequency coefficients that reach 1.00 at 100 kHz and 300 kHz.
• Loss Angle (tan δ): tanδ = 0.12 specified at 20°C, 120 Hz, indicating controlled dissipation for thermal and AC performance planning.
• Leakage Current: Specified leakage current of 540 µA (after 2 minutes at 20°C), enabling predictable bias behavior in DC circuits.
• Thermal Endurance & Lifetime: Rated life of 2000 hours at 105°C; category temperature range from -55°C to +105°C for broad environmental use.
• SMD Can Package: φ10 × 7.7 mm radial can SMD with embossed carrier taping and moisture-proof packing for automated assembly and inventory handling.
• Assembly Compatibility: Lead-free reflow soldering support with peak condition up to 260°C as specified for SMD assembly processes.
• RoHS Compliance: Meets RoHS directive requirements as stated in product information.

Typical Applications

• General-purpose electronics — Specified for "General Purpose" use where a 270 µF, 10 V surface-mount capacitor is required for bulk capacitance or decoupling.
• Compact power modules — Small φ10 × 7.7 mm SMD package with 3.5 A high-frequency ripple rating supports dense power converter and regulator designs.
• High-frequency decoupling — Low ESR (25 mΩ at 100 kHz) and frequency ripple coefficients reaching 1.00 at 100 kHz/300 kHz make it suitable for high-frequency noise suppression in power rails.

Unique Advantages

• Predictable high-frequency performance: Specified ESR at 100 kHz and defined frequency coefficients enable confident selection for switching and high-frequency applications.
• Compact SMD can package: φ10 × 7.7 mm radial can provides substantial capacitance in a board-friendly surface-mount form factor.
• Robust thermal profile: Rated for -55°C to +105°C with a 2000-hour endurance at 105°C for predictable lifetime under elevated temperatures.
• High ripple handling: Clear low- and high-frequency ripple specifications (350 mA at 120 Hz; 3.5 A at 300 kHz) let designers size capacitors to real ripple environments.
• Assembly-ready packaging: Embossed carrier taping and moisture-proof packing support automated placement and storage of SMD components.
• Measured leakage and dissipation data: Leakage current (540 µA) and tanδ (0.12) are specified for straightforward thermal and bias margin calculations.
