RS80J681MDN1

The RS80J681MDN1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a low-profile, radial-lead can. Designed for general-purpose power applications, it delivers high ripple current capability and low ESR/ESL in a compact φ6.3×8 mm package with 2.5 mm lead spacing.

Its combination of 680 µF capacitance, 6.3 V rating and a −55 °C to 105 °C operating range makes it suitable for compact power-supply decoupling and high-frequency smoothing where space and thermal endurance are important. The part is supplied in bulk/bag packing for volume production and is RoHS compliant.

Key Features

• Conductive polymer aluminum solid electrolyte Provides stable electrical performance with low ESR behavior compared with traditional wet electrolytic types.
• Capacitance & voltage 680 µF nominal capacitance at a rated voltage of 6.3 V with ±20% tolerance.
• Low ESR / ESL Specified ESR of 8 mΩ at 100 kHz (20 °C), delivering reduced loss and improved efficiency at switching frequencies.
• High ripple current capability Rated ripple current of 470 mA at 120 Hz and 4.7 A at 300 kHz; frequency coefficient for ripple current reaches 1.00 at 100 kHz and 300 kHz.
• Compact radial package Low-profile can φ6.3×8 mm with 2.5 mm lead spacing and radial leads for through-hole mounting and compact board layouts.
• Wide temperature and rated life Operates from −55 °C to 105 °C with a rated load life of 2000 hours at 105 °C.
• Polarized, general-purpose use Polarized construction intended for general-purpose power filtering and smoothing applications.
• RoHS compliant and production-ready Supplied in bulk/bag packing for mass production and compliant with RoHS requirements.

Typical Applications

• Power-supply decoupling — Compact decoupling and bulk storage on DC-DC converter outputs where low ESR and high ripple handling reduce voltage ripple.
• High-frequency switching regulators — Output filtering and energy buffering in switch-mode power supplies that operate at 100 kHz–300 kHz frequencies.
• Embedded and consumer electronics — Space-constrained boards requiring a low-profile, through-hole capacitor for smoothing and transient suppression.
• Communications and industrial electronics — Local energy storage and ripple management in compact power modules and control circuitry.

Unique Advantages

• Space-efficient low-profile design: φ6.3×8 mm can and 2.5 mm lead spacing enable compact through-hole layouts without sacrificing capacitance.
• High-frequency performance: 8 mΩ ESR at 100 kHz and frequency coefficients that reach 1.00 at 100 kHz/300 kHz support effective high-frequency ripple handling.
• Robust ripple capability: Rated ripple current up to 4.7 A at 300 kHz allows the capacitor to handle significant AC stress in switching applications.
• Wide operating range and proven life: −55 °C to 105 °C rating with 2000 hours endurance at 105 °C provides predictable behavior under elevated temperature load.
• Production-ready packaging: Bulk/bag packing and mass-production availability ease procurement for volume manufacturing.
• Regulatory compliance: RoHS compliance supports deployment in regulated markets.
