RDS1C121MCNAHFGS

The RDS1C121MCNAHFGS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in an SMD radial can package. It delivers 120 µF at 16 V with a polarized design and is built for high-capacitance, high-ripple applications in compact surface-mount assemblies.

Engineered for demanding thermal and ripple environments, this part offers lead-free reflow compatibility to a 260°C peak and RoHS compliance (2011/65/EU, (EU)2015/863), making it suitable for modern production processes and regulatory requirements.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance at 16 V with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Low ESR — ESR of 23 mΩ measured at 100 kHz, supporting efficient high-frequency performance and reduced power loss.
• High Ripple Current — Rated ripple current of 1.8 A at 300 kHz and 180 mA at 120 Hz, suitable for applications with significant AC current components.
• Wide Temperature Range & Endurance — Operating temperature from −55°C to +125°C with a load life of 3000 hours at 125°C, for sustained performance in elevated-temperature environments.
• Surface-Mount Radial Can Package — Compact dimensions L: 6.7 × D: 8 mm with recommended land size L: 8.3 × W: 8.3 mm for PCB mounting.
• Assembly Compatibility — SMD type designed for lead-free reflow soldering up to a 260°C peak.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized Electrolyte — Polar capacitor construction for DC bias applications.

Typical Applications

• Power supply decoupling — Bulk and high-frequency decoupling where low ESR and high ripple current reduce voltage ripple on power rails.
• DC–DC converter outputs — Output smoothing in compact converters benefiting from high capacitance and high-frequency ripple capability.
• Industrial and telecommunications power modules — Power filtering in environments demanding extended thermal endurance (−55°C to +125°C) and long load life at high temperature.
• Compact embedded systems — Board-level energy storage and transient handling in space-constrained SMD assemblies using a radial can package.

Unique Advantages

• High ripple handling for robust power rails — 1.8 A at 300 kHz and low ESR (23 mΩ) reduce heating and improve stability under AC stress.
• Thermal endurance for extended operation — 3000 hours at 125°C provides verifiable lifecycle performance in elevated-temperature applications.
• SMD radial-can form factor — Compact L: 6.7 × D: 8 mm size and defined land pattern (8.3 × 8.3 mm) simplify PCB layout for surface-mount assembly.
• Lead‑free reflow compatible — Built for modern assembly processes with a 260°C peak reflow capability.
• Regulatory-ready — RoHS compliance supports restricted-substance requirements for global supply chains.
