RS80J681MCN1

The RS80J681MCN1 is a conductive polymer aluminum solid electrolytic capacitor from Nichicon's RS8 series designed for general-purpose electronic applications. It combines low ESR/ESL construction with a compact, low-profile radial-can package to deliver high ripple-current capability in space-constrained assemblies.

Key value propositions include low equivalent series resistance at high frequency, robust ripple-current handling, and a parts footprint optimized for radial lead mounting and lead-free flow soldering processes.

Key Features

• Electrical Performance — 680 µF capacitance at 6.3 V with ±20% tolerance; polarized design suitable for DC filter and decoupling applications.
• Low ESR / High-Frequency Behavior — ESR specified at 8 mΩ measured at 100 kHz (20°C), providing reduced loss at high switching frequencies.
• High Ripple-Current Capability — Rated ripple current of 470 mA at 120 Hz and 4.7 A at 300 kHz, enabling effective smoothing under varying frequency conditions.
• Compact Low-Profile Package — φ6.3 × 8 mm can with 2.5 mm lead spacing; radial lead mounting for through-hole assemblies.
• Thermal and Lifetime Ratings — Operating temperature range of −55°C to +105°C with a specified load life of 2000 hours at 105°C for the part.
• Manufacturing Compatibility — Radial lead type with lead-free flow soldering condition correspondence and RoHS compliance (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic designs — Bulk decoupling and smoothing in compact power supply and control circuits where a low-profile radial capacitor is required.
• High-frequency power stages — Applications that benefit from low ESR at 100 kHz and elevated ripple-current ratings.
• Through-hole assemblies — Radial lead package fits PCB layouts with limited board area and standard lead spacing (2.5 mm).

Unique Advantages

• Low ESR at high frequency: 8 mΩ specified at 100 kHz (20°C) for reduced losses in switching and high-frequency circuits.
• High ripple-current handling: Rated for 470 mA at 120 Hz and 4.7 A at 300 kHz, supporting both low- and high-frequency ripple scenarios.
• Space-efficient low-profile can: φ6.3 × 8 mm package minimizes board area while providing substantial capacitance (680 µF).
• Robust thermal performance: −55°C to +105°C operating range with a specified load life of 2000 hours at 105°C for sustained reliability under elevated temperatures.
• Assembly-ready and compliant: Radial lead format compatible with lead-free flow soldering processes and RoHS-compliant materials.
