RS81E680MCN1

The RS81E680MCN1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a compact radial-lead can (φ6.3 × 8 mm). It delivers 68 µF capacitance at a 25 V rating with a ±20% tolerance and is designed for general-purpose electronic applications that require a low-profile, high-ripple, low-ESR capacitor.

Key value propositions include low equivalent series resistance (18 mΩ at 20°C/100 kHz), strong high-frequency ripple handling (up to 3.5 A at 300 kHz), and extended operating conditions across −55°C to 105°C with a rated endurance of 2000 hours at 105°C.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic construction for stable electrical performance.
• Capacitance & Voltage 68 µF capacitance rated at 25 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low ESR & High-Frequency Performance ESR of 18 mΩ (20°C/100 kHz) and a tangent of loss angle (tan δ) of 0.1 (20°C/120 Hz) to support low-loss operation.
• High Ripple Current Capability Rated ripple current of 350 mA at 120 Hz and 3.5 A at 300 kHz for demanding AC and switching environments.
• Thermal & Lifetime Characteristics Operating temperature range −55°C to 105°C with a load life (endurance) of 2000 hours at 105°C.
• Compact Radial Package Low-profile can, φ6.3 × 8 mm, radial lead mounting (lead spacing 2.5 mm, tolerance ±0.5 mm) for board-level space efficiency.
• Leakage & Measurement Conditions Leakage current specified at 510 µA (measured after 2 minutes at 20°C); DF measurement condition 20°C, 120 Hz.
• Packaging & Compliance Available in Bulk (no terminal forming) or Bag packing; RoHS compliant and in mass production.

Typical Applications

• General-purpose electronics — A compact radial-lead conductive polymer capacitor option for general-purpose designs that require 68 µF at 25 V within −55°C to 105°C operating range.
• Space-constrained boards — Low-profile φ6.3 × 8 mm package and 2.5 mm lead spacing make it suitable where board height and footprint are limited.
• Power-stage filtering — Low ESR (18 mΩ at 100 kHz) and high ripple current rating (3.5 A at 300 kHz) support filtering and smoothing in power circuits that match the specified voltage and temperature ranges.

Unique Advantages

• Low ESR for efficient performance: 18 mΩ measured at 20°C/100 kHz reduces losses at high frequency and helps maintain voltage stability in switching environments.
• High ripple handling: Rated ripple currents of 350 mA (120 Hz) and 3.5 A (300 kHz) enable reliable operation under significant AC ripple conditions within the specified ratings.
• Compact, low-profile form factor: φ6.3 × 8 mm radial-can package provides a small board footprint while preserving capacitor capability.
• Wide temperature and rated-life specification: −55°C to 105°C operating range and 2000-hour endurance at 105°C support long-term use in elevated-temperature environments.
• Production-ready and compliant: Mass-production status and RoHS compliance simplify procurement and regulatory acceptance.
• Practical lead configuration: Radial leads with 2.5 mm spacing (±0.5 mm tolerance) suit through-hole PCB layouts and straightforward manual or wave assembly options (packaging offered in Bulk/Bag).
