RDS1C271MCNAHFGS

The RDS1C271MCNAHFGS is a conductive polymer aluminum solid electrolytic capacitor delivering high capacitance and high ripple-current capability in a compact surface-mount can. Designed for reliable operation across a wide temperature range (−55°C to 125°C) and a rated voltage of 16 V, it targets power management and board-level decoupling where high stability under elevated temperature and frequency is required.

Key value comes from its combination of 270 µF capacitance, low ESR, and a 3000-hour load life at 125°C, enabling sustained performance in demanding thermal and ripple environments while supporting lead-free reflow processes.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 16 V provides substantial bulk and decoupling capability for low-voltage power rails.
• Conductive Polymer Architecture — Solid electrolyte construction for stable electrical characteristics with reduced leakage behavior compared to some wet electrolytes.
• Low ESR & High-Frequency Performance — ESR of 23 mΩ measured at 100 kHz and specified ripple current of 1.8 A at 300 kHz support high-frequency switching environments.
• High Ripple Endurance — Rated ripple current of 180 mA at 120 Hz and frequency coefficients documented through 300 kHz enable predictable thermal and ripple handling across frequencies.
• Extended High-Temperature Life — Load life rating of 3000 hours at 125°C under rated voltage for long-term reliability in elevated-temperature applications.
• Surface-Mount, Reflow-Compatible Package — Radial can SMD package (φ8 × 6.7 mm) optimized for PCB assembly and compatible with lead-free reflow peak temperature of 260°C.
• Wide Operating Temperature — Specified for −55°C to +125°C operation to accommodate harsh thermal conditions.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements for restricted substances.

Typical Applications

• Power Supply Smoothing — High capacitance and low ESR provide effective bulk filtering for 16 V and lower power rails, reducing voltage ripple from switching converters.
• DC–DC Converter Output Filtering — Rated ripple current at high frequency (1.8 A at 300 kHz) supports switching regulator outputs and point-of-load decoupling.
• Industrial Electronics — Extended load life at 125°C and wide temperature operation make the part suitable for control and instrumentation electronics exposed to elevated temperatures.
• Compact Board-Level Power Modules — Small φ8 × 6.7 mm SMD can allows integration into dense power assemblies where board real estate and thermal endurance are required.

Unique Advantages

• High ripple capability: 1.8 A ripple current rating at 300 kHz enables robust handling of high-frequency switching currents without rapid degradation.
• Low ESR at operating frequencies: 23 mΩ ESR at 100 kHz reduces I2R losses and improves transient response in power delivery networks.
• Long high-temperature lifetime: 3000 hours at 125°C under rated voltage supports designs that must maintain capacitance and ESR stability over extended periods in hot environments.
• Reflow-compatible SMD design: Lead-free reflow compatibility up to a 260°C peak simplifies assembly into modern SMT manufacturing flows.
• Compact footprint: φ8 × 6.7 mm can provides a balance of capacitance and board area for densely populated PCBs.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for commercial and industrial products.
