RFS1C220MCN1GS

The RFS1C220MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor rated at 22 µF and 16 V. It combines low equivalent series resistance (ESR) and high ripple-current capability in a compact radial can SMD package for general-purpose electronic designs.

Designed for applications that demand stable capacitance over a wide temperature range, this component delivers measurable performance benefits—low ESR, defined leakage, and a 2000-hour endurance at 105°C—making it suitable for dense power and filtering circuits in industrial and commercial electronics.

Key Features

• Capacitance & tolerance — 22 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Voltage rating — 16 V rated voltage suitable for a range of low-voltage power rails.
• Low ESR — 45 mΩ ESR measured at 20°C/100 kHz, minimizing voltage drop under AC conditions.
• High ripple current capability — 121 mA at 120 Hz (low frequency) and 1.21 A at 300 kHz (high frequency), supporting both low- and high-frequency filtering tasks.
• Leakage current — Specified leakage current of 100 µA after 2 minutes at 20°C under rated voltage.
• Robust thermal endurance — Rated for 2000 hours at 105°C, with an operating temperature range from −55°C to 105°C.
• Compact SMD package — Radial, can-style SMD with dimensions L: 5.7 × D: 5 mm (φ5 × 5.7 mm case); supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Manufacturing compatibility — Lead-free reflow soldering condition correspondence up to a 260°C peak.
• Regulatory — RoHS compliant.

Typical Applications

• Power rail smoothing — Low ESR and rated ripple currents suit local decoupling and smoothing on low-voltage power rails.
• Switching regulator output filtering — High-frequency ripple capability supports output filtering in DC–DC converters and point-of-load modules.
• General-purpose industrial electronics — Temperature endurance to 105°C and 2000-hour life make it appropriate for continuous-duty industrial control and instrumentation circuits.
• Compact SMD designs — Small radial can SMD format and taped packaging enable automated placement in space-constrained assemblies.

Unique Advantages

• Measurable low-loss performance: 45 mΩ ESR at 100 kHz reduces AC losses and supports tighter voltage regulation in power circuits.
• Frequency-flexible ripple handling: Specified ripple currents at both 120 Hz and 300 kHz provide predictable behavior across low- and high-frequency filtering tasks.
• Thermal reliability: 2000-hour rated life at 105°C and an operating range of −55°C to 105°C support designs with elevated ambient or sustained thermal stress.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing streamlines high-volume SMD assembly and inventory handling.
• Clear electrical limits: Defined leakage current (100 µA) and capacitance tolerance (±20%) enable straightforward component selection and margining in circuit design.
