RDS1A121MCNAFEGS

The RDS1A121MCNAFEGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 120 µF capacitance at 10 V. Engineered for high ripple-current handling and extended thermal endurance, it serves designs that require stable capacitance and low ESR across a wide temperature span.

Its combination of 25 mΩ ESR (100 kHz), high-frequency ripple capability, and 3000-hour load life at 125°C targets electronic systems where reliability, compact SMD packaging (φ6.3×5.7 mm), and RoHS compliance are required.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance at 10 V with tolerance −20% to +20%.
• Low ESR — Equivalent series resistance of 25 mΩ measured at 100 kHz, supporting low-loss operation at higher switching frequencies.
• High Ripple Current — Rated ripple current up to 180 mA at 120 Hz and 1.8 A at 300 kHz, enabling robust AC performance across a wide frequency range.
• Wide Temperature Range — Operates from −55°C to 125°C, suited for thermally demanding environments.
• Long Life / Endurance — Rated for 3000 hours at 125°C under rated voltage, maintaining capacitance, tan δ and ESR within specified endurance limits.
• Leakage & Dissipation — Leakage current up to 700 µA (after 2 minutes at 20°C); tan δ 0.12 measured at 20°C, 120 Hz.
• SMD Package & Assembly Ready — φ6.3×5.7 mm radial can SMD with embossed carrier taping and moisture-proof packing compatible with standard SMT handling and lead‑free reflow processes.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• High-temperature electronics — Circuits and modules that must operate reliably between −55°C and 125°C, leveraging the capacitor’s 3000-hour rated life at 125°C.
• High-frequency power rails — Designs requiring high-frequency ripple current capability up to 1.8 A at 300 kHz together with low ESR (25 mΩ).
• Compact SMD power subsystems — Space-constrained boards needing a φ6.3×5.7 mm SMD capacitor with significant capacitance (120 µF) and robust soldering/handling packaging.

Unique Advantages

• High ripple-current capacity: Rated ripple current values at both low and high frequencies support demanding switching and filtering conditions.
• Thermal endurance: 3000-hour load life at 125°C provides quantifiable reliability for thermally stressed designs.
• Low ESR at RF: 25 mΩ ESR at 100 kHz reduces conduction losses and improves efficiency in high-speed power circuits.
• Soldering and assembly ready: Supplied on embossed carrier tape with moisture‑proof packing for streamlined SMT line integration and lead‑free reflow compatibility.
• Predictable leakage behavior: Specified leakage current limit (700 µA) simplifies bias and power-loss budgeting in system designs.
