RSB0E561MCN1GS

The RSB0E561MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for general-purpose power applications. It delivers high capacitance in a compact φ6.3 × 5.7 mm SMD can, optimized for low ESR and high ripple handling at low voltages.

Engineered for applications requiring stable bulk capacitance and robust ripple performance, this device targets power management, decoupling, and energy storage roles where a 2.5 V rating, wide temperature range, and long endurance are required.

Key Features

• Capacitance — 560 µF nominal capacitance with tolerance of -20% to +20%, suitable for bulk decoupling and energy storage.
• Rated Voltage — 2.5 V rated voltage, with a surge rating of 2.8 V as defined in the series datasheet.
• Low ESR — ESR of 10 mΩ measured at 20°C / 100 kHz, enabling efficient power delivery and reduced heat under AC ripple.
• High Ripple Current — Handles up to 380 mA at 120 Hz (low frequency) and up to 3.8 A at 300 kHz (high frequency), supporting high-frequency switching supplies.
• Temperature and Endurance — Operating range from -55°C to +105°C with a load life of 2000 hours at 105°C.
• Loss Tangent — tan δ of 0.12 (20°C, 120 Hz), indicating the specified dissipation factor under typical measurement conditions.
• Leakage Current — Specified leakage current of 700 µA (measured after standard conditioning), suitable for power circuits where controlled leakage is required.
• Compact SMD Package — φ6.3 × 5.7 mm can (package case: radial, can - SMD) with surface mount land size L: 6.5 × W: 6.5 mm for space-constrained PCB layouts.
• Packaging — Supplied in embossed carrier taping with moisture-proof packing for SMT assembly and storage.
• Regulatory — RoHS compliant; part is in mass production.

Typical Applications

• Point-of-load power filtering — Low ESR and high high-frequency ripple current make this capacitor suitable for smoothing outputs of switching regulators at 2.5 V rails.
• Bulk decoupling for power rails — High capacitance in a compact SMD can provides local energy storage for transient loads.
• High-frequency power stages — Elevated ripple current capability at 300 kHz supports use near power transistors and converters in compact designs.
• Industrial and consumer electronics — Wide temperature range (-55°C to +105°C) and long endurance (2000 h at 105°C) fit sustained operation in varied environments.

Unique Advantages

• Efficient power delivery: 10 mΩ ESR at 100 kHz reduces voltage drop and dissipation in high-current paths, improving converter efficiency.
• High ripple tolerance: 3.8 A capability at high frequency (300 kHz) and 380 mA at 120 Hz lets you place bulk capacitance close to switching nodes.
• Space-optimized form factor: φ6.3 × 5.7 mm SMD can provides 560 µF without a large PCB footprint, simplifying board layout in dense designs.
• Robust thermal and lifetime profile: -55°C to +105°C operating range with 2000 hours endurance at 105°C supports long-term reliability in demanding environments.
• Manufacturing-ready supply: Embossed carrier taping and moisture-proof packing support automated SMT assembly and storage logistics.
• Regulatory compliance: RoHS status ensures alignment with environmental requirements for many product lines.
