RL80E122MDN1

The RL80E122MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial lead package from Nichicon's RL8 series. It delivers 1.2 mF capacitance at 2.5 V with ultra-low ESR and high ripple-current capabilities for general-purpose electronic designs.

Designed for compact assemblies, this φ8×8 mm radial can supports demanding thermal and ripple conditions with an operating range from −55°C to 105°C and a rated life of 2000 hours at 105°C.

Key Features

• Conductive Polymer Electrolyte Solid conductive polymer construction provides low ESR and stable performance under ripple stress.
• Low Equivalent Series Resistance (ESR) ESR = 7 mΩ measured at 20°C/100 kHz, reducing losses and heat generation in high-frequency applications.
• High Ripple Current Rated ripple current of 610 mA at 120 Hz (low frequency) and 6.1 A at 300 kHz (high frequency), supporting heavy AC loading.
• Compact, Low-Profile Package Size φ8 × 8 mm with 3.5 mm lead spacing (±0.5 mm), suitable for space-constrained through-hole layouts.
• Electrical Characteristics Capacitance 1.2 mF with tolerance −20% to +20%; tanδ = 0.12 at 20°C/120 Hz; leakage current specified at 750 µA.
• Thermal and Endurance Ratings Operating temperature range −55°C to 105°C and rated life/endurance of 2000 hours at 105°C under rated voltage.
• Assembly and Compliance Radial lead configuration with lead-free flow soldering condition correspondence; RoHS compliant and available in bulk/bag packing.

Typical Applications

• Power Supply Filtering General-purpose smoothing and filtering where low ESR and high ripple current minimize voltage ripple and thermal rise.
• DC–DC Converter Output Bulk and decoupling capacitance for converters that benefit from high-frequency ripple handling and compact footprint.
• High-Frequency Power Circuits Applications requiring stable performance at 100 kHz–300 kHz thanks to low ESR and rated high-frequency ripple current.
• Embedded and Industrial Electronics Through-hole radial format and wide temperature range make it suitable for general-purpose embedded and industrial boards.

Unique Advantages

• Low ESR for Lower Losses: 7 mΩ ESR at 100 kHz reduces I²R losses and operating temperature in high-frequency applications.
• High Ripple-Endurance: Rated ripple currents of 610 mA (120 Hz) and 6.1 A (300 kHz) help manage AC stress without rapid degradation.
• Space-Efficient Form Factor: φ8×8 mm low-profile can saves board area while providing 1.2 mF capacitance for bulk energy storage.
• Wide Temperature and Proven Endurance: −55°C to 105°C operating range and 2000-hour life at 105°C give predictable performance in thermal stress conditions.
• Through-Hole Assembly Friendly: Radial leads with 3.5 mm spacing simplify placement and soldering in through-hole production environments.
• RoHS Compliant and Production Ready: Environmentally compliant and listed as mass production, enabling straightforward procurement and deployment.
