RS81E820MCN1

The RS81E820MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial lead package. It delivers 82 µF at 25 V with a compact φ6.3 × 8 mm can and 2.5 mm lead spacing, designed for general-purpose electronic designs that require low ESR and high ripple capability.

Built for robust operation across a wide temperature range (−55 °C to 105 °C) and offered in mass-production packaging options (bulk / bag), this part targets compact power and signal-conditioning circuits where low loss and reliable performance matter.

Key Features

• Electrical Performance: 82 µF nominal capacitance with ±20% tolerance and rated voltage of 25 V, suitable for a variety of general-purpose circuits.
• Low ESR / High-Frequency Response: ESR of 18 mΩ measured at 20 °C / 100 kHz and tanδ of 0.1 (20 °C, 120 Hz), enabling efficient AC performance and reduced dissipation at high frequencies.
• High Ripple Current Capability: Rated ripple current of 350 mA at 120 Hz (low frequency) and 3.5 A at 300 kHz (high frequency), supporting demanding ripple conditions in switching and high-frequency applications.
• Temperature & Reliability: Operating range −55 °C to 105 °C with a rated life/endurance of 2000 hours at 105 °C.
• Compact, Low-Profile Package: φ6.3 × 8 mm can with 2.5 mm lead spacing and radial lead mounting for through-hole assemblies where board space is constrained.
• Leakage & Quality: Specified leakage current of 615 µA (measured after 2 minutes at 20 °C) and RoHS compliance for regulatory alignment.
• Packaging & Availability: Available in bulk (no terminal forming) or bag packing and listed as in mass production.

Typical Applications

• Compact Power Modules: Low-profile radial package and high ripple capability make it suitable for space-constrained power module input/output filtering.
• High-Frequency Power Supplies: Low ESR (18 mΩ @100 kHz) and substantial high-frequency ripple handling support switching regulator and point-of-load filtering.
• General-Purpose Electronics: General-purpose circuits requiring stable capacitance over −55 °C to 105 °C and endurance at elevated temperatures.

Unique Advantages

• Low-loss operation: Low ESR and specified tanδ reduce heat generation and improve efficiency in AC and high-frequency environments.
• High ripple tolerance: Rated ripple currents up to 3.5 A at high frequency enable use in demanding switching and decoupling applications.
• Space-efficient form factor: φ6.3 × 8 mm can and 2.5 mm lead spacing allow designers to minimize board footprint while retaining through-hole mounting ease.
• Wide temperature capability: −55 °C to 105 °C operating range and 2000-hour endurance at 105 °C support reliable operation in thermally active systems.
• Regulatory readiness: RoHS compliance ensures the part meets common environmental requirements.
• Production-ready supply: Offered in mass-production quantities with bulk or bag packing formats for scalable assembly needs.
