RDS1C121MCNAFEGS

The RDS1C121MCNAFEGS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount package, offering 120 µF at 16 V. It combines high capacitance with low ESR and high ripple-current capability for compact, temperature-demanding board-level power applications.

Designed for SMD assembly, this part supports lead-free reflow conditions up to a 260°C peak and is RoHS compliant. The device is specified for continuous operation from −55°C to 125°C with a rated load life of 3000 hours at 125°C.

Key Features

• Capacitance and Voltage — Rated at 120 µF and 16 V with a capacitance tolerance of ±20% at 120 Hz, 20°C.
• Low ESR — Equivalent series resistance of 24 mΩ measured at 100 kHz, 20°C, supporting efficient high-frequency performance.
• High ripple-current capability — Rated ripple current of 1.8 A at 300 kHz and 180 mA at 120 Hz, enabling effective smoothing and decoupling under dynamic loads.
• High-temperature endurance — Rated for operation to 125°C and qualified for a load life of 3000 hours at 125°C.
• SMD, lead-free reflow compatible — Surface-mount radial can package designed for lead-free reflow soldering with a 260°C peak.
• Wide operating temperature range — Specified from −55°C to +125°C for reliability across demanding thermal environments.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact footprint — Small package dimensions (L: 5.7 × D: 6.3 mm) for space-constrained board designs.

Typical Applications

• Surface-mount power decoupling — Low ESR and high ripple-current handling make this capacitor suitable for board-level decoupling and filtering in SMD power circuits.
• High-temperature electronics — Rated to 125°C with a 3000-hour life at that temperature, suitable for assemblies exposed to elevated operating temperatures.
• Compact power modules — The small L: 5.7 × D: 6.3 mm package supports dense PCB layouts where high capacitance is required in limited space.

Unique Advantages

• High ripple-current tolerance — 1.8 A at 300 kHz and defined ripple values at lower frequencies help reduce thermal stress and improve capacitor stability under dynamic loads.
• Low ESR for high-frequency performance — 24 mΩ at 100 kHz minimizes losses and improves efficiency in switching and high-frequency circuits.
• Extended high-temperature life — 3000 hours at 125°C provides predictable long-term performance in thermally challenging environments.
• Surface-mount, lead-free reflow compatible — SMD radial can designed for 260°C peak lead-free reflow streamlines modern assembly processes.
• Regulatory compliance — RoHS conformity supports use in designs that require restricted-substance compliance.
• Small package for space optimization — Compact dimensions enable higher component density without sacrificing capacitance or performance.
