RSA0E471MCN1GS

The RSA0E471MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount can (φ6.3×5.7 mm) offering 470 µF capacitance at 2.5 V. It delivers low ESR and high ripple current capability for general-purpose power filtering and decoupling in space-constrained electronic designs.

Designed for reliability in elevated-temperature environments, this SMD capacitor is rated for operation from -55°C to 105°C and has a load-life specification of 2000 hours at 105°C, making it suitable for applications that require sustained performance under thermal stress.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 2.5 V and ±20% tolerance (measured at 20°C, 120 Hz).
• Low ESR & High-frequency Performance — ESR specified at 13 mΩ (20°C, 100 kHz) to support low-loss decoupling and high-frequency operation.
• High Ripple Current Capability — Rated ripple current of 360 mA at 120 Hz (low frequency) and 3.6 A at 300 kHz (high frequency) for efficient smoothing in switching power stages.
• Temperature Range & Endurance — Operating temperature from -55°C to 105°C with a life/endurance rating of 2000 hours at 105°C under rated voltage.
• Leakage & Loss Characteristics — Leakage current specified at 700 µA and tangent of loss angle (tan δ) of 0.12 measured at 20°C, 120 Hz.
• Compact SMD Package — Radial, can-style SMD package with dimensions φ6.3 × 5.7 mm and recommended land size 6.5 × 6.5 mm for board-level integration.
• Assembly & Packaging — SMD type suitable for lead-free reflow (260°C peak per datasheet) and supplied in embossed carrier tape with moisture-proof packing for automated placement.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk decoupling and smoothing in low-voltage power rails where 470 µF at 2.5 V and low ESR improve transient response and stability.
• Switching regulator output capacitors — Supports high ripple currents up to 3.6 A at high frequency, suitable for compact DC–DC converter outputs and power modules.
• Compact electronics and modules — Small φ6.3×5.7 mm SMD footprint fits space-constrained designs that require higher capacitance and reliable thermal endurance.

Unique Advantages

• Low-loss power delivery: 13 mΩ ESR at 100 kHz reduces conduction losses and improves efficiency in power conversion and filtering circuits.
• High ripple capability: 3.6 A rated ripple current at 300 kHz enables robust handling of switching currents in high-frequency converters.
• Solid conductive polymer construction: Polymer electrolyte supports low ESR and stable performance over frequency and temperature.
• Thermal endurance: 2000-hour life at 105°C under rated voltage provides predictable long-term behavior in elevated-temperature applications.
• Board-level ready: SMD can package with embossed carrier tape and moisture-proof packing streamlines automated assembly and inventory handling.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for modern electronic products.
