RDS1A101MCNAFEGS

The RDS1A101MCNAFEGS is a surface-mount conductive polymer aluminum electrolytic capacitor delivering 100 µF at 10 V in a compact φ6.3 × 5.7 mm can. Designed for applications that require high capacitance, low ESR and sustained performance at elevated temperatures, it targets power stages and filtering tasks in industrial and communications equipment.

This part combines a low ESR of 25 mΩ (measured at 100 kHz) with high ripple capability (up to 1.8 A at 300 kHz) and a rated operating range of −55 °C to +125 °C with a 3000-hour load life at 125 °C, providing reliable filtering and decoupling in thermally demanding designs.

Key Features

• Capacitance & Tolerance — 100 µF nominal capacitance with tolerance ±20% at 120 Hz, 20 °C for predictable bulk energy storage and decoupling.
• Low ESR & High Ripple Capability — ESR of 25 mΩ (100 kHz) combined with rated ripple current up to 1.8 A at 300 kHz supports high-frequency switching applications and reduces losses.
• Wide Temperature and Long Life — Specified to operate from −55 °C to +125 °C with an endurance rating of 3000 hours at 125 °C for sustained performance in hot environments.
• Electrical Loss and Leakage — tanδ of 0.12 (20 °C, 120 Hz) and a specified leakage current up to 700 µA, enabling predictable AC loss and DC leakage behavior.
• Compact SMD Package — Radial can SMD package sized φ6.3 × 5.7 mm with surface-mount land footprint 6.5 × 6.5 mm for space-efficient board layouts.
• Assembly Compatibility — SMD type designed for lead-free reflow soldering (260 °C peak), supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS Compliant — Meets RoHS directive requirements for environmental compliance.

Typical Applications

• Power conversion (DC–DC stages) — Bulk smoothing and output filtering where 100 µF at 10 V, low ESR and 1.8 A ripple capability support stable regulator performance.
• Switch-mode power supplies — Input/output decoupling for switching regulators operating at high frequencies; low ESR and frequency-rated ripple current mitigate thermal rise.
• Industrial electronics — Capacitor for power rails in equipment exposed to elevated temperatures, leveraging the −55 °C to +125 °C range and 3000-hour life at 125 °C.
• Telecom and networking modules — Local energy storage and noise suppression for high-frequency communication circuits that require compact, high-capacitance SMD components.

Unique Advantages

• High ripple tolerance in compact form: Low ESR (25 mΩ) and rated ripple up to 1.8 A at 300 kHz enable effective filtering in space-constrained boards.
• Thermal endurance for demanding environments: Rated for −55 °C to +125 °C and validated for 3000 hours at 125 °C, supporting long-term operation under high-temperature stress.
• Predictable electrical behavior: Specified tanδ (0.12 at 20 °C, 120 Hz) and defined leakage current limits (700 µA) help designers budget losses and standby current precisely.
• Surface-mount assembly ready: SMD radial can with embossed carrier taping and moisture-proof packing simplifies automated placement and lead-free reflow processes.
• Regulatory compliance: RoHS compliance reduces material compliance risk for global product deployment.
