RL80E821MDN1

The RL80E821MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead can, delivering 820 µF at 2.5 V in a low‑profile φ8×8 mm package. It is designed for general‑purpose electronic applications requiring low ESR and high ripple current in a compact radial format.

This part combines ultra low ESR performance (6 mΩ at 20°C/100 kHz) with high frequency ripple capability (6.1 A at 300 kHz) and a wide operating temperature range of −55°C to 105°C, offering reliable bulk energy storage and decoupling in space‑constrained designs.

Key Features

• Core Performance — 820 µF, 2.5 V High capacitance in a low rated voltage for bulk smoothing and decoupling in compact circuits.
• Ultra Low ESR ESR specified at 6 mΩ (20°C/100 kHz) to minimize voltage drop and dissipation at high frequency.
• High Ripple Current Capability Rated ripple current 610 mA at 120 Hz and 6.1 A at 300 kHz, supporting both low‑ and high‑frequency power filtering.
• Low Loss (tan δ) tan δ of 0.12 measured at 20°C/120 Hz for predictable AC behavior and stability.
• Thermal and Endurance Specification Operating range −55°C to 105°C with a rated load life of 2000 hours at 105°C.
• Compact Radial Package φ8×8 mm can with 3.5 mm lead spacing and radial leads for through‑hole mounting and simple mechanical retention.
• Leakage Current Specified leakage current of 512 µA measured at 20°C after 2 minutes, useful for predictable standby behavior.
• RoHS Compliant & Production Ready RoHS compliant and listed as mass production, suitable for deployment in production BOMs.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling where low ESR and high ripple current improve regulator stability and transient response.
• Compact power modules — Low‑profile φ8×8 package allows use in space‑constrained assemblies needing high capacitance at low voltage.
• High‑frequency bypassing — Specified performance at 100 kHz and 300 kHz supports high‑speed switching environments and point‑of‑load capacitors.

Unique Advantages

• Low‑impedance power delivery: 6 mΩ ESR at 100 kHz reduces supply ripple and thermal loss in high‑current circuits.
• High ripple handling across frequencies: 610 mA at 120 Hz and 6.1 A at 300 kHz provide flexibility for both mains‑frequency and switching‑frequency applications.
• Compact, low‑profile form factor: φ8×8 mm can with radial leads and 3.5 mm lead spacing simplifies placement in tight through‑hole layouts.
• Wide operating temperature: −55°C to 105°C supports deployment across varied thermal environments.
• Endurance for reliable operation: Rated for 2000 hours at 105°C to help ensure predictable service life under high‑temperature load conditions.
• Production and compliance ready: RoHS compliant and listed as mass production for straightforward procurement and integration.
