RL80G821MDN1

The RL80G821MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile, radial-lead can (φ8×8 mm) offering 820 µF nominal capacitance at a 4 V rating. Designed for general-purpose electronic designs, it delivers low equivalent series resistance and high ripple-current capability in a compact through-hole package.

Key value comes from its ultra low ESR (6 mΩ at 20°C/100 kHz), high-frequency ripple tolerance (6.1 A at 300 kHz), and a wide operating temperature range from -55°C to 105°C, coupled with 2000 hours of rated-life endurance at 105°C.

Key Features

• Capacitance and Voltage — 820 µF nominal capacitance with a rated voltage of 4 V and tolerance of -20% to +20%.
• Low ESR — ESR of 6 mΩ measured at 20°C/100 kHz, enabling low-loss operation at high frequencies.
• High Ripple Current — Low-frequency ripple current of 610 mA (120 Hz) and high-frequency ripple capability up to 6.1 A (300 kHz), supporting demanding ripple environments.
• Dielectric Loss — tanδ (DF) of 0.12 measured at 20°C, 120 Hz, suitable for stable performance in AC conditions.
• Reliability and Endurance — Rated life of 2000 hours at 105°C under rated voltage with specified limits on capacitance change, tanδ and ESR after test.
• Temperature Range — Operational from -55°C to 105°C for wide environmental compatibility.
• Compact Radial Package — φ8×8 mm can with 3.5 mm lead spacing and radial through-hole mounting for compact PCB layouts and robust mechanical retention.
• Leakage Current — Specified leakage current of 820 µA (measured after 2 minutes at 20°C under rated voltage).
• Compliance and Availability — RoHS compliant and in mass production; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General Purpose Electronics — Suited for designs that require 820 µF at 4 V with low ESR and defined ripple-current handling for general-purpose energy storage and decoupling.
• Compact, Low-Profile Assemblies — φ8×8 mm low-height packaging fits space-constrained boards where through-hole mounting is preferred.
• High-Frequency Power Environments — The 6 mΩ ESR at 100 kHz and 6.1 A ripple capability at 300 kHz make this part appropriate for applications with significant high-frequency ripple currents.
• Through-Hole Manufacturing — Radial lead form and 3.5 mm lead spacing support standard through-hole assembly and robust mechanical connection.

Unique Advantages

• Low-loss operation: 6 mΩ ESR at 20°C/100 kHz minimizes power dissipation and thermal rise under high-frequency AC loading.
• High ripple tolerance: Rated ripple currents of 610 mA (120 Hz) and 6.1 A (300 kHz) reduce the need for parallel components in ripple-heavy circuits.
• Space-efficient form factor: φ8×8 mm can and 8 mm height provide a compact footprint for through-hole designs without sacrificing capacitance.
• Robust thermal endurance: 2000 hours at 105°C rated life supports sustained operation in elevated-temperature environments.
• Predictable electrical characteristics: Specified tanδ (0.12 at 20°C/120 Hz) and leakage current values enable straightforward system-level margining.
• RoHS compliant and production-ready: Meets RoHS requirements and is available in mass-production quantities with bulk or bag packing options.
