RFS1E220MCN1GS

The RFS1E220MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It provides 22 µF capacitance at a 25 V rating with low ESR and high ripple capability, designed for general-purpose electronic designs.

Engineered for reliability across a wide temperature range (−55 °C to 105 °C) and a 2000-hour endurance at 105 °C, this SMD capacitor supports compact board-level power and decoupling needs where low loss and high ripple tolerance are required.

Key Features

• Dielectric / Construction — Conductive polymer aluminum solid electrolyte construction for stable capacitance and conductivity in a compact SMD can.
• Capacitance & Voltage — 22 µF rated capacitance at 25 V with ±20% tolerance (at 120 Hz, 20 °C).
• Low ESR — ESR 40 mΩ measured at 20 °C / 100 kHz, supporting low-loss performance at high frequencies.
• High Ripple Current — Rated ripple current of 220 mA at 120 Hz and 2.2 A at 300 kHz, enabling robust handling of both low- and high-frequency ripple.
• Leakage Current — Leakage current specified at 300 µA (after 2 minutes at 20 °C), supporting predictable bias behavior.
• Temperature & Endurance — Operating range −55 °C to 105 °C with a load life of 2000 hours at 105 °C.
• Package & PCB Integration — φ5 × 5.7 mm case (L: 5.7 × D: 5 mm) for space-efficient SMD placement; recommended land size L: 5.3 × W: 5.3 mm. Supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Lead-free Reflow Compatibility — Compatible with lead-free reflow soldering conditions up to a 260 °C peak.
• Compliance — RoHS compliant.

Typical Applications

• General Purpose Electronics — Suited for board-level designs that require 22 µF capacitance and 25 V rating in a compact SMD package.
• Power and Decoupling Circuits — Applicable where low ESR and high ripple current capability are needed to support stable power rails and decoupling.
• High-Frequency Circuits — Specified ESR at 100 kHz and ripple coefficients up to 300 kHz make it suitable for high-frequency smoothing and filtering tasks.

Unique Advantages

• Low ESR for reduced losses: 40 mΩ ESR at 20 °C / 100 kHz minimizes dissipation and supports efficient operation in frequency-sensitive circuits.
• High ripple tolerance: 2.2 A ripple current rating at 300 kHz and 220 mA at 120 Hz enables handling of both HF and LF ripple stress.
• Compact SMD can: φ5 × 5.7 mm package balances capacitance and board space, simplifying integration in dense layouts.
• Extended thermal endurance: Rated for 2000 hours at 105 °C and an operating range down to −55 °C for reliable performance across temperature extremes.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing and reflow compatibility streamline automated production flows.
• predictable leakage behavior: 300 µA leakage current specification supports reliable bias calculations and system-level power management.
