RDS1A820MCNAFEGS

The RDS1A820MCNAFEGS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a compact SMD can package. It delivers high capacitance and high ripple-current capability in a surface-mount form factor intended for compact power delivery and decoupling applications.

With an 82 µF, 10 V rating, low ESR and wide operating temperature range, this part targets designs that require robust high-frequency smoothing and sustained performance at elevated temperatures.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic construction for stable capacitance and low-loss performance.
• Capacitance & Voltage 82 µF nominal capacitance with ±20% tolerance and a 10 V rated voltage.
• Low ESR & High Ripple Capability ESR of 25 mΩ (measured at 100 kHz, 20°C) and a high-frequency ripple current rating of 1.8 A at 300 kHz (180 mA at 120 Hz), suitable for demanding switching environments.
• Thermal Endurance Rated for operation from −55°C to +125°C with a guaranteed load life of 3000 hours at 125°C.
• Assembly Compatibility Surface-mount radial can (SMD) designed for lead-free reflow soldering with a 260°C peak compatibility.
• Package & Footprint Compact dimensions L: 5.7 × D: 6.3 mm and recommended land pattern L: 6.5 × W: 6.5 mm for tight board layouts.
• Compliance RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• DC–DC converter outputs Low ESR and 1.8 A ripple capability at high frequency make this capacitor suitable for output smoothing and energy buffering in compact regulator stages.
• Power supply decoupling Compact SMD can and low impedance support decoupling at high switching frequencies in power delivery networks.
• Industrial and telecom power modules Extended temperature range (−55°C to +125°C) and 3000-hour life at 125°C enable use in temperature-challenged power subsystems.
• Embedded and compact electronics Small footprint (5.7 × 6.3 mm) and lead-free reflow compatibility suit dense PCB layouts where board space and reflow reliability matter.

Unique Advantages

• High ripple-current handling: The 1.8 A rating at 300 kHz and low ESR (25 mΩ at 100 kHz) reduce voltage ripple and thermal stress in switching power stages.
• High-temperature endurance: A 3000-hour rated life at 125°C provides predictable aging and long-term stability in hot environments.
• Compact SMD can: Small dimensions and a defined land pattern enable space-efficient PCB designs without sacrificing capacitance.
• Reflow-ready, lead-free assembly: Designed for 260°C peak lead-free reflow processes to fit modern manufacturing flows.
• RoHS compliance: Meets current RoHS directives for environmentally regulated designs.
