RSL0E221MCN1GB

The RSL0E221MCN1GB is a conductive polymer aluminum solid electrolytic capacitor in a low-profile surface-mount can (φ6.3) designed for compact, high-performance board-level power applications. It delivers 220 µF at 2.5 V with low ESR and high ripple-current capability, making it suitable for dense PCB layouts where space and thermal endurance matter.

Built for reliability in elevated-temperature environments, the part is rated for operation from –55 °C to +105 °C, accepts lead-free reflow soldering up to a 260 °C peak, and carries RoHS compliance.

Key Features

• Dielectric / Electrolyte: Conductive polymer aluminum solid electrolyte providing stable capacitance in a compact SMD can.
• Capacitance & Voltage: 220 µF rated capacitance at 2.5 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Low ESR & Loss: ESR of 16 mΩ measured at 100 kHz, 20 °C and tan δ of 0.12, supporting efficient high-frequency performance.
• High Ripple Current: Rated ripple current up to 3.5 A at 300 kHz (frequency-dependent behavior applies; coefficient data available in the datasheet).
• Thermal Endurance: Load life specified at 2000 hours at 105 °C, with operating temperature range from –55 °C to +105 °C.
• Leakage Current & Surge: Leakage current ≤ 300 µA (measured at 20 °C after 2 minutes) and surge voltage rating of 2.8 V.
• Package & Mounting: Low-profile SMD radial can, case size φ6.3 × L4.2 mm, seated height 4.2 mm, surface-mount land recommendation 6.5 × 6.5 mm.
• Manufacturing Compatibility: SMD type compatible with lead-free reflow soldering condition at a 260 °C peak; RoHS directive compliant.

Typical Applications

• General-purpose board-level power management: Low ESR and 220 µF bulk capacitance support local energy buffering and stability on power rails in compact designs.
• High-frequency decoupling and filtering: 16 mΩ ESR at 100 kHz combined with strong high-frequency ripple capability (3.5 A at 300 kHz) helps suppress switching noise in dense layouts.
• Thermally demanding electronics: Rated for continuous operation up to 105 °C with a 2000-hour load-life specification for sustained performance in elevated-temperature assemblies.

Unique Advantages

• Compact, low-profile can: φ6.3 × 4.2 mm case delivers significant capacitance in a small SMD footprint, enabling space-efficient board designs.
• High ripple-current handling: Up to 3.5 A at high frequency reduces voltage ripple and improves regulator stability without oversized components.
• Low ESR for efficient power delivery: 16 mΩ ESR at 100 kHz minimizes loss and heat generation under dynamic loads.
• Extended high-temperature life: 2000 hours at 105 °C provides predictable aging characteristics for longer service in hot environments.
• Assembly-ready: Lead-free reflow compatibility (260 °C peak) and RoHS compliance simplify modern manufacturing flow and regulatory adherence.
