RL80E122MDNASQ

The RL80E122MDNASQ is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial-can package (φ8×8 mm). It delivers high ripple-current capability and ultra-low ESR in a compact, radial-leaded form factor for general-purpose electronic applications.

Designed as part of Nichicon's RL8 series, this part combines a 1.2 mF capacitance at 2.5 V with a wide operating temperature range and long endurance, providing a reliable solution where compact bulk capacitance and high-frequency performance are required.

Key Features

• Conductive polymer solid electrolyte — Solid polymer construction for stable electrical characteristics and improved ripple performance compared with traditional wet electrolytes.
• High capacitance in a compact package — 1.2 mF (1200 μF) at 2.5 V in a φ8×8 mm can provides substantial bulk capacitance in a low-profile footprint.
• Ultra-low ESR — ESR of 7 mΩ measured at 20°C/100 kHz, enabling reduced impedance at high frequencies.
• High ripple-current capability — Rated ripple current of 610 mA at 120 Hz and 6.1 A at 300 kHz supports switching and high-frequency power rails.
• Low loss tangent — tanδ of 0.12 measured at 20°C/120 Hz for predictable AC loss characteristics.
• Long endurance — Rated for 5000 hours at 105°C, supporting sustained operation under elevated temperature conditions.
• Robust environmental range — Operating temperature from −55°C to +105°C to accommodate a wide range of operating conditions.
• Radial-lead, board-ready package — φ8×8 mm radial can with 3.5 mm lead spacing (±0.5 mm) and compatibility with lead-free flow soldering conditions; available in bulk or bag packing.
• Regulatory status — RoHS compliant and in mass production.

Typical Applications

• General-purpose power filtering — Low ESR and high ripple-current capability make this capacitor suitable for smoothing and decoupling on power rails in general electronic designs.
• Switching regulator support — Compact bulk capacitance and high-frequency ripple ratings help stabilize DC–DC converters and switching power supplies.
• Embedded and industrial electronics — Low-profile φ8×8 package and extended temperature range (−55°C to +105°C) accommodate constrained PCB layouts and varied thermal environments.

Unique Advantages

• High energy density in a low-profile can — 1.2 mF in a φ8×8 mm package reduces board area while providing significant bulk capacitance.
• Minimized AC impedance — 7 mΩ ESR at 100 kHz lowers voltage ripple and improves transient response for high-speed power circuits.
• Handles demanding ripple currents — 6.1 A rating at high frequency supports modern switching topologies and reduces the need for parallel parts.
• Durable under elevated temperature — 5000-hour endurance at 105°C supports long-term reliability in thermally stressed designs.
• Assembly-friendly radial format — Radial leads with standard 3.5 mm spacing and lead-free flow solder compatibility simplify through-hole assembly processes.
• RoHS compliant and production-ready — Mass-production status and environmental compliance streamline sourcing and qualification.
