RL80G821MDNASQ

The RL80G821MDNASQ is a conductive polymer aluminum solid electrolytic capacitor in a low-profile, radial-lead can (φ8×8 mm) designed for general-purpose electronic applications. It delivers high ripple-current capability and ultra-low ESR in a compact, radial package for space-constrained power designs.

Key attributes include 820 µF capacitance at 4 V, an ESR of 6 mΩ measured at 20°C/100 kHz, a rated operating range of −55°C to 105°C, and a 5000-hour endurance at 105°C—providing a balance of performance and reliability for demanding board-level power circuits.

Key Features

• Capacitance and Voltage — 820 µF nominal capacitance with a rated voltage of 4 V and a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Low ESR — ESR of 6 mΩ specified at 20°C/100 kHz for reduced AC loss and improved efficiency in high-frequency applications.
• High Ripple Current Handling — Rated ripple current of 610 mA at 120 Hz and 6.1 A at 300 kHz, enabling robust smoothing and decoupling under varying frequency loads.
• Low Loss Angle (tan δ) — tanδ of 0.12 (20°C, 120 Hz), supporting stable performance across intended conditions.
• Reliability and Life — Endurance rated 5000 hours at 105°C; leakage current specified at 820 µA after standard conditioning.
• Compact Radial Package — φ8×8 mm can with 3.5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assembly and easy placement in compact designs.
• Manufacturing and Compliance — Lead-free flow soldering condition correspondence and RoHS-compliant; available in bulk (no terminal forming) or bag packing. Product is in mass production.

Typical Applications

• General-purpose power filtering — Compact decoupling and smoothing where low ESR and high ripple current capacity improve voltage stability on power rails.
• Embedded and board-level power modules — Low-profile φ8 package and radial leads make it suitable for tight layouts requiring through-hole mounting while maintaining high-frequency performance.
• High-frequency power circuits — High ripple current rating at 300 kHz and low ESR support applications with significant AC components or switching activity.

Unique Advantages

• High ripple tolerance in a small footprint: 6.1 A ripple current capability at 300 kHz combined with a φ8×8 mm package enables effective filtering without large can sizes.
• Low ESR for improved efficiency: 6 mΩ ESR at 100 kHz minimizes AC losses and heat generation in high-frequency circuits.
• Wide operating temperature: −55°C to 105°C rating supports designs exposed to broad thermal environments.
• Long endurance at elevated temperature: 5000-hour life at 105°C helps ensure sustained performance in continuous-duty applications.
• Radial-lead convenience: Through-hole mounting with defined lead spacing simplifies placement in mixed-technology PCBs and prototyping.
• RoHS-compliant manufacturing: Meets RoHS requirements and supports lead-free flow soldering conditions for modern assembly processes.
