RR71A221MDN1

The RR71A221MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, rated 220 µF at 10 V and polarized for general-purpose electronic designs. It combines ultra-low ESR and high ripple current capability with a wide operating temperature range to support demanding power-filtering and decoupling roles.

Designed for reliability in compact assemblies, this radial-lead capacitor offers measurable endurance at elevated temperature and is RoHS compliant, making it suitable for a range of general-purpose applications that require stable capacitance and low loss.

Key Features

• Capacitance and Voltage: 220 µF nominal capacitance at a rated voltage of 10 V with ±20% tolerance.
• Low ESR: 7 mΩ equivalent series resistance measured at 100 kHz, reducing power loss and heating in high-frequency applications.
• High Ripple Current Handling: Rated ripple current of 610 mA at 120 Hz (low frequency) and 6.1 A at 300 kHz (high frequency), supporting both low- and high-frequency ripple environments.
• Temperature and Endurance: Operating temperature range from −55°C to +105°C with a rated life of 2000 hours at 105°C.
• Package and Mounting: Radial lead, polarized aluminum can with 5 mm lead spacing; physical dimensions L: 1.25 cm × D: 1.00 cm for compact PCB layouts.
• Solder and Environmental Compliance: Radial lead type compatible with lead-free flow soldering conditions and compliant with RoHS requirements.

Typical Applications

• Power supply filtering: Low ESR (7 mΩ) and high ripple current capability (6.1 A at 300 kHz) make it suitable for smoothing and local energy storage in power regulation circuits.
• DC–DC converter outputs: Compact radial package and high-frequency ripple handling support output filtering in space-constrained converter designs.
• General-purpose electronics: Polarized aluminum construction and broad temperature range (−55°C to +105°C) for use across diverse consumer and industrial general-purpose circuits.

Unique Advantages

• Measurable low-loss performance: 7 mΩ ESR at 100 kHz reduces dissipation and improves efficiency in high-frequency applications.
• Broad ripple capability: Dual-specified ripple ratings (610 mA at 120 Hz and 6.1 A at 300 kHz) provide predictable performance across low and high frequency regimes.
• Compact radial form factor: 1.25 cm × 1.00 cm can size with 5 mm lead spacing simplifies integration into tight PCB layouts while retaining radial-lead mounting convenience.
• High-temperature endurance: Rated for 2000 hours at 105°C, offering a defined thermal life performance for elevated-temperature designs.
• Regulatory and process readiness: RoHS compliant and compatible with lead-free flow soldering conditions for contemporary manufacturing processes.
