RS80E821MCNASQ

The RS80E821MCNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead, low-profile can (φ6.3×8 mm). It delivers high capacitance (820 µF) at a low rated voltage (2.5 V) while maintaining a compact footprint and through-hole mounting compatibility.

Designed for general-purpose power and decoupling applications, the device combines low ESR and high ripple-current capability with a wide operating temperature range (−55 °C to +105 °C) and a long rated lifetime at elevated temperature (5000 h at 105 °C).

Key Features

• Core Technology  Conductive polymer aluminum solid electrolytic construction for stable capacitance and improved high-frequency performance.
• Capacitance & Tolerance  820 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C.
• Low ESR  Equivalent series resistance of 7 mΩ measured at 100 kHz, supporting efficient filtering and low-loss operation.
• High Ripple Current  Rated ripple current up to 5.6 A at 300 kHz and 560 mA at 120 Hz, enabling robust handling of switching currents.
• Compact, Low-Profile Package  φ6.3 × 8 mm can with 2.5 mm lead spacing, radial-lead mounting for easy through-hole assembly.
• Thermal and Lifetime Performance  Operating temperature range −55 °C to +105 °C with a rated lifetime of 5000 hours at 105 °C.
• Polarized, Through-Hole Form  Polar capacitor with standard radial leads; supplied in bulk bag packing for production use.
• RoHS Compliant  Meets RoHS environmental requirements.

Typical Applications

• General-purpose power filtering  Use for bulk decoupling and smoothing on low-voltage power rails where high capacitance and low ESR improve stability.
• High-frequency switching regulation  Suitable for local energy storage on switching regulator outputs due to elevated ripple-current capability at high frequency.
• Compact through-hole modules  Low-profile φ6.3×8 mm package and 2.5 mm lead spacing make it suitable for space-constrained, through-hole boards.
• Embedded and consumer electronics  Provides stable capacitance across −55 °C to +105 °C for general-purpose designs that require reliable decoupling.

Unique Advantages

• Low-loss performance: 7 mΩ ESR at 100 kHz reduces dissipation and improves filtering efficiency in high-frequency circuits.
• High ripple current capacity: Rated up to 5.6 A at 300 kHz (and 560 mA at 120 Hz), allowing the capacitor to handle demanding switching currents without excessive heating.
• Space-efficient form factor: φ6.3×8 mm low-profile can and 2.5 mm lead spacing minimize board area while preserving through-hole mounting simplicity.
• Long high-temperature life: Rated for 5000 hours at 105 °C, supporting reliable operation in elevated-temperature environments.
• Production-friendly packaging: Supplied in bulk (no terminal forming) / bag packing for mass-production assembly workflows.
• Regulatory compliance: RoHS-compliant construction supports environmental and regulatory requirements.
