RFS1C101MCN1GS

The RFS1C101MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It provides 100 µF capacitance at a 16 V rating with a compact φ5 × 5.7 mm case optimized for high ripple handling and low equivalent series resistance.

Designed for general-purpose electronic designs, this SMD capacitor delivers low ESR and high ripple current performance with a load life of 2000 hours at 105°C and an operating temperature range of −55°C to 105°C. It is supplied in embossed carrier taping with moisture-proof packing for assembly readiness.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with ±20% tolerance at a rated voltage of 16 V, suitable for general-purpose decoupling and energy storage needs.
• Low Loss Tangent — tanδ of 0.12 (measured at 120 Hz, 20°C) supporting stable AC performance.
• Low ESR — ESR of 27 mΩ at 20°C/100 kHz, enabling efficient high-frequency operation and reduced power dissipation.
• High Ripple Current Capability — Rated ripple current of 300 mA at 120 Hz and 3 A at 300 kHz, supporting applications with significant AC ripple and switching noise.
• Leakage Current & Reliability — Leakage current specified at 320 µA after 2 minutes at 20°C; rated life of 2000 hours at 105°C under rated voltage.
• Surface-Mount Package — Compact radial SMD can, φ5 × 5.7 mm (L × D), with recommended land size L: 5.3 × W: 5.3 mm for PCB placement.
• Assembly-Ready Packaging — Embossed carrier taping with moisture-proof packing for automated placement and handling.
• RoHS Compliant — Conforms to RoHS directives.
• Reflow Compatibility — SMD type compatible with lead-free reflow soldering conditions (260°C peak), per series datasheet guidance.

Typical Applications

• General-purpose electronic designs — Provides bulk capacitance and noise suppression where a compact SMD capacitor is required.
• Surface-mount power modules — Low ESR and high ripple current ratings make it suitable for power-regulation circuitry in compact assemblies.
• High-frequency decoupling — ESR and ripple performance at 100 kHz and above support decoupling in switching environments.

Unique Advantages

• High ripple handling in a small package: 3 A rated ripple at 300 kHz combined with a φ5 × 5.7 mm case enables compact designs without sacrificing AC performance.
• Low dissipation and improved efficiency: 27 mΩ ESR at 100 kHz reduces losses and heating in power-conversion and filtering applications.
• Robust thermal endurance: 2000-hour life at 105°C supports long-term reliability in thermally demanding environments.
• Assembly-ready SMD format: Embossed carrier taping and moisture-proof packing streamline automated placement and storage.
• Predictable leakage behavior: Specified leakage current of 320 µA after conditioning provides quantifiable standby/idle current characteristics for designers.
