RFS0G151MCN1GS

The RFS0G151MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for general-purpose SMD applications. It delivers high capacitance (150 µF) at a low rated voltage (4 V) in a compact φ5 × 5.7 mm can-style package suited for space- and performance-constrained designs.

Built for stability and high-frequency performance, this capacitor combines low ESR (22 mΩ at 20°C/100 kHz), high ripple current capability, and extended endurance (2000 hours at 105°C) to support robust power decoupling and bulk energy storage in demanding thermal and frequency environments.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte design for stable electrical characteristics and improved high-frequency behavior.
• High capacitance in a compact SMD can — 150 µF in a φ5 × 5.7 mm package (radial, can - SMD) for space-efficient bulk capacitance.
• Low ESR — 22 mΩ measured at 20°C/100 kHz, supporting reduced power loss and improved ripple handling.
• High ripple current capability — Rated ripple current 2.61 A at 300 kHz (and 261 mA at 120 Hz), enabling effective filtering at high switching frequencies.
• Endurance and thermal range — Load life rated 2000 hours at 105°C with operating temperature range –55°C to 105°C for thermal reliability in elevated environments.
• Electrical stability metrics — tanδ (DF) of 0.12 measured at 20°C/120 Hz and leakage current specified at 300 µA (after 2 minutes at 20°C), providing predictable behavior for circuit design.
• Surface-mount packaging and handling — Supplied in embossed carrier taping with moisture-proof packing for automated assembly and storage stability.
• RoHS compliant — Conforms to applicable RoHS requirements.

Typical Applications

• General-purpose power filtering: Suitable for bulk decoupling and smoothing on compact power rails where 150 µF capacitance and low ESR improve transient response.
• High-frequency switching supplies: Supports high ripple currents up to 2.61 A at 300 kHz, helping to handle switching noise and ripple in DC–DC converters.
• Compact embedded systems: Small φ5 × 5.7 mm footprint and surface-mount format make it useful where board area is limited but high capacitance is required.

Unique Advantages

• High energy density in a small package: 150 µF in a φ5 × 5.7 mm SMD can reduces board space while providing substantial bulk capacitance.
• Improved thermal endurance: 2000-hour life at 105°C supports longer field life in elevated-temperature applications.
• Reduced losses at high frequency: 22 mΩ ESR at 100 kHz lowers dissipation and supports efficient power delivery in switching circuits.
• High ripple handling: Rated ripple current of 2.61 A at 300 kHz enables reliable performance with high-frequency power converters and drivers.
• Predictable electrical behavior: Specified tanδ (0.12 at 20°C/120 Hz) and leakage (300 µA) allow designers to budget loss and leakage precisely.
• Production-ready packaging: Embossed carrier taping with moisture-proof packing simplifies automated placement and inventory handling.
