RS80E331MDN1

The RS80E331MDN1 is a conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RS8 series. It is a polarized, radial-lead, low-profile (φ6.3×8 mm) component designed for general-purpose electronic circuits requiring a compact, low-ESR energy storage element.

This part delivers a combination of low equivalent series resistance, high ripple-current capability, and a wide operating temperature range, making it suitable for through‑hole PCB designs that require reliable decoupling or bulk capacitance at low voltage.

Key Features

• Capacitance & Rated Voltage — 330 µF rated capacitance at 2.5 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low ESR / High Ripple Handling — ESR of 7 mΩ measured at 100 kHz; rated ripple current values include 560 mA at 120 Hz and 5.6 A at 300 kHz.
• Low Profile Radial Package — Small footprint: φ6.3 × 8 mm (D×L) with 2.5 mm lead spacing; radial lead (can) package for through‑hole mounting.
• Temperature Range & Endurance — Operates from −55°C to +105°C with a specified load life of 2000 hours at 105°C.
• Conductive Polymer Solid Electrolyte — Solid polymer chemistry and polarized construction for stable performance and low loss.
• Assembly & Compliance — Radial lead type compatible with lead-free flow soldering conditions and compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Circuitry — Use where a 330 µF, 2.5 V polarized capacitor is required for bulk capacitance or decoupling in through‑hole designs.
• Through‑Hole PCB Assemblies — Suited to designs that use radial lead components and require compatibility with lead‑free flow soldering.
• Temperature‑Constrained Designs — Appropriate for applications that operate within −55°C to +105°C and require a capacitor rated for 2000 hours at 105°C.

Unique Advantages

• Low ESR for Improved Voltage Stability: 7 mΩ ESR at 100 kHz reduces voltage drop under high-frequency load transients.
• High Ripple Capability: Rated ripple currents of 560 mA (120 Hz) and 5.6 A (300 kHz) support circuits with significant AC content across the capacitor.
• Compact, Low‑Profile Footprint: φ6.3×8 mm size provides substantial capacitance in a small radial package to save board space.
• Robust Operating Range: −55°C to +105°C rating and 2000 h life at 105°C provide predictable endurance in elevated-temperature environments.
• Manufacturing‑Ready: Radial lead form factor with lead‑free flow soldering compatibility eases integration into standard through‑hole assembly flows.
• Regulatory Compliance: RoHS compliance (2011/65/EU, (EU)2015/863) supports environmental regulatory requirements.
