RSS1E220MCN1GS

The RSS1E220MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It delivers 22 µF capacitance at a 25 V rating with low ESR and high ripple-current capability for compact, performance-focused designs.

Engineered for general-purpose surface-mount applications, this RoHS-compliant capacitor combines a small φ6.3×5.7 mm footprint and lead‑free reflow compatibility with a 2000‑hour endurance at 105°C to support reliable operation across a −55°C to 105°C temperature range.

Key Features

• Capacitance & Voltage — 22 µF rated capacitance at 25 V for bulk decoupling and energy storage in compact SMD designs.
• Low ESR & High Ripple Current — ESR of 40 mΩ (20°C, 100 kHz) combined with rated ripple currents of 210 mA at 120 Hz and 2.1 A at 300 kHz reduces losses and supports high-frequency ripple handling.
• Loss Tangent & Leakage — tanδ of 0.12 (20°C, 120 Hz) and leakage current specified at 110 µA, providing predictable impedance and leakage characteristics for design validation.
• Temperature & Endurance — Operating range −55°C to 105°C with a rated load life of 2000 hours at 105°C for sustained performance in elevated-temperature environments.
• Surface‑Mount Package — Compact φ6.3×5.7 mm (L: 5.7 × D: 6.3 mm) radial can SMD package with surface-mount land recommendation (6.6 × 6.6 mm) for space-constrained PCBs.
• Assembly & Compliance — SMD type specified for lead‑free reflow soldering (260°C peak) and supplied in embossed carrier taping with moisture‑proof packing; RoHS compliant.

Typical Applications

• General-purpose power filtering — Low ESR (40 mΩ) and high ripple-current capability (2.1 A at 300 kHz) make it suitable for board-level decoupling and smoothing in compact power circuits.
• High-frequency ripple absorption — Rated ripple performance at both low and high frequencies supports designs that require stable high-frequency filtering in limited board area.
• Compact SMD assemblies — The φ6.3×5.7 mm radial can SMD package fits densely packed PCBs while providing solid electrolytic capacitance and endurance.

Unique Advantages

• Predictable impedance profile: Specified tanδ (0.12 at 20°C/120 Hz) and ESR (40 mΩ at 100 kHz) enable accurate AC performance modeling and component selection.
• High ripple tolerance: 2.1 A at 300 kHz and 210 mA at 120 Hz provide margin for handling both low- and high-frequency ripple currents in power stages.
• Compact, solder‑compatible package: Surface-mount radial can (φ6.3×5.7 mm) and lead‑free reflow compatibility simplify automated assembly in modern production flows.
• Temperature resilience and endurance: −55°C to 105°C range with 2000 hours life at 105°C supports designs exposed to elevated operating temperatures.
• Supply-chain ready packaging: Embossed carrier taping and moisture‑proof packing facilitate handling, storage, and placement in high-volume manufacturing.
