RS80E122MCN1

The RS80E122MCN1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial-lead package (φ6.3×8 mm). It delivers 1.2 mF capacitance at a 2.5 V rating with a wide operating temperature range of −55 °C to 105 °C for compact board-level power applications.

Engineered for low equivalent series resistance and high ripple capability, this part targets general-purpose electronic designs where compact size, high-frequency performance and robust endurance matter. It is RoHS compliant and available in bulk or bag packing for production use.

Key Features

• Dielectric / Construction: Conductive polymer aluminum solid electrolyte construction for stable electrical characteristics in a polarized radial-lead format.
• Capacitance & Voltage: 1.2 mF (1200 µF) nominal capacitance with tolerance −20% to 20% and rated voltage 2.5 V.
• Low ESR & High-Frequency Performance: ESR 7 mΩ measured at 20 °C / 100 kHz and tanδ 0.1 (20 °C, 120 Hz), enabling low-loss operation at high frequencies.
• High Ripple Current Capability: Rated ripple current 560 mA at 120 Hz and 5.6 A at 300 kHz (frequency coefficients support full rated ripple at 100–300 kHz).
• Compact Low-Profile Package: Small footprint φ6.3 × 8 mm (length × diameter), radial lead spacing 2.5 mm (±0.5 mm) suitable for space-constrained PCB layouts; lead diameter 0.6 mm.
• Reliability & Endurance: Load-life rating of 2000 hours at 105 °C, leakage current 750 µA (after 2 minutes at 20 °C), and operating temperature −55 °C to 105 °C.
• Mounting & Packing: Radial lead mounting type with bulk (no terminal forming) or bag packing options; compatible with lead-free flow soldering conditions per datasheet notes.
• Compliance: RoHS compliant.

Typical Applications

• General Purpose Electronics: Fits general-purpose board-level roles where a compact, low-ESR radial capacitor is required.
• Compact Power Circuits: Suited to tight-space power modules and assemblies that require high ripple handling in a low-profile package.
• High-Frequency Filtering: Applicable to PCB-level filtering tasks that benefit from low ESR at 100 kHz and above.

Unique Advantages

• High ripple acceptance in a small package: 5.6 A ripple capability at high frequency combined with a φ6.3×8 mm footprint enables aggressive power-density designs.
• Low-loss performance: 7 mΩ ESR at 100 kHz and tanδ 0.1 at 120 Hz reduce dissipation and improve efficiency in high-frequency applications.
• Wide temperature range and endurance: −55 °C to 105 °C rating plus 2000 h life at 105 °C provide predictable behavior across typical industrial operating conditions.
• Radial-lead form factor: Through-hole radial mounting with 2.5 mm lead spacing simplifies placement in mixed through-hole/SMT assemblies and supports lead-free flow soldering conditions.
• Production-ready packaging: Available in bulk or bag packing to support prototyping through mass production workflows.
