RSL0J221MCN1GB

The RSL0J221MCN1GB is a conductive polymer aluminum solid electrolytic capacitor in a compact, low‑profile SMD can (φ6.3×4.2 mm). Engineered for general‑purpose electronic designs, it delivers high capacitance and low equivalent series resistance in a surface‑mount package.

Key value comes from a combination of low ESR and high ripple‑current capability, a 2000‑hour load life at 105 °C, lead‑free reflow compatibility to a 260 °C peak, and RoHS compliance—making it suitable for compact power and decoupling applications requiring thermal endurance and high AC current handling.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 6.3 V, with capacitance tolerance ±20% (measured at 120 Hz, 20 °C).
• Low ESR — ESR specified at 18 mΩ (measured at 100 kHz, 20 °C), supporting efficient high‑frequency decoupling and reduced heat generation.
• High Ripple Current — Rated for 3.2 A at 300 kHz; datasheet also cites 3,200 mArms (100 kHz, 100 °C) for this 6.3 V, 220 µF RSL part, enabling robust AC current handling.
• Compact, Low‑Profile SMD — Surface‑mount radial can in φ6.3×4.2 mm package (land size L: 6.5 × W: 6.5 mm), optimized for space‑constrained PCB layouts.
• Thermal & Endurance Rating — Operating temperature range −55 °C to +105 °C with a rated load life of 2000 hours at 105 °C (endurance test conditions per datasheet).
• Leakage Current — Typical leakage current listed as 693 µA (@20 °C, after 2 minutes) for the 220 µF, 6.3 V variant, consistent with solid polymer electrolytes.
• Assembly & Compliance — SMD type compatible with lead‑free reflow soldering conditions (260 °C peak) and compliant to RoHS directives.

Typical Applications

• General‑purpose electronics — Compact surface‑mount decoupling and bulk capacitance in consumer and industrial PCBs where low ESR and high ripple tolerance are required.
• Power supply modules — Local energy storage and smoothing in small footprint power converters using SMD assembly processes.
• High‑frequency circuits — AC ripple handling and filtering in circuits operating at high switching or switching‑frequency harmonics, enabled by the low ESR and high ripple current ratings.

Unique Advantages

• Space‑efficient performance: Low‑profile φ6.3×4.2 mm package provides high 220 µF capacitance in a compact SMD can, reducing PCB area for power bus components.
• Lower power loss: 18 mΩ ESR at 100 kHz reduces I²R losses and heating under ripple currents, improving thermal margin in dense designs.
• High AC endurance: 3.2 A ripple specification at 300 kHz and 3,200 mArms at 100 kHz (100 °C) supports demanding ripple environments in switching supplies.
• Robust thermal life: 2000‑hour load life at 105 °C delivers predictable lifetime behavior for sustained elevated‑temperature operation.
• Assembly friendly: Designed for lead‑free reflow up to a 260 °C peak, simplifying integration into modern SMD production flows.
• Regulatory compliance: RoHS conformity ensures alignment with common environmental requirements for commercial and industrial products.
