RS80E821MCN1

The RS80E821MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial-lead can (φ6.3×8 mm). Designed for general-purpose power applications, it delivers high ripple-current capability and low equivalent series resistance (ESR) in a compact footprint.

Its primary value is reliable power-filtering and bulk decoupling in compact assemblies, offering a wide operating temperature range and defined endurance at elevated temperature for sustained performance in demanding environments.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic capacitor for stable performance and low ESR.
• Capacitance & Voltage 820 µF rated capacitance with a rated voltage of 2.5 V and tolerance of -20% to +20%.
• Low Loss (tan δ) tanδ (DF) = 0.10 measured at 20°C, 120 Hz, supporting low-loss operation in filtering applications.
• Very Low ESR ESR = 7 mΩ measured at 20°C/100 kHz, enabling improved transient response and reduced I²R losses.
• High Ripple Current Low-frequency ripple current 560 mA (120 Hz) and high-frequency ripple current 5.6 A (300 kHz), with frequency coefficients: 0.10 @120 Hz, 0.45 @1 kHz, 0.50 @10 kHz, 1.00 @100 kHz and 1.00 @300 kHz.
• Leakage Current Leakage current specified as 512 µA (conditioned per datasheet measurement practice).
• Temperature & Endurance Operating temperature range −55°C to +105°C and rated life of 2000 hours at 105°C.
• Package & Mechanical Radial lead can, size φ6.3 × 8 mm, lead spacing 2.5 mm (tolerance 0.5 mm); available in bulk (no terminal forming) or bag packing.
• Compliance & Availability RoHS compliant and in mass production.

Typical Applications

• Power conversion modules Bulk smoothing and decoupling for DC–DC converters and switching regulators where low ESR and high ripple current are required.
• Point-of-load filtering Local energy storage and transient suppression on compact power rails in space-constrained boards.
• Portable and handheld equipment Compact low-profile package suits tight enclosures requiring reliable power filtering over a wide temperature range.
• Industrial control electronics Power smoothing and energy buffering in control and instrumentation circuits that operate up to 105°C.

Unique Advantages

• Low ESR for improved efficiency: 7 mΩ ESR at 100 kHz reduces power loss and improves converter efficiency and transient response.
• High ripple capability: 5.6 A ripple current at high frequency supports demanding switching supply environments.
• Compact low-profile form: φ6.3×8 mm radial can fits dense, height-restricted assemblies without sacrificing capacitance.
• Wide temperature and proven endurance: −55°C to +105°C operating range and 2000 h life at 105°C support long-term reliability in elevated-temperature applications.
• Design-friendly packaging: Radial lead and 2.5 mm lead spacing simplify through-hole assembly and layout for mixed-technology boards.
• Regulatory readiness: RoHS compliance supports deployment in markets with restricted substance requirements.
