RNU1E680MCN1

The RNU1E680MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can designed for general-purpose electronic applications. It combines low ESR and high ripple-current capability with a compact φ8×11.5 mm package, making it suitable for designs that require reliable power filtering and decoupling across a wide temperature range.

Key attributes include 68 μF nominal capacitance at 25 V, a wide operating temperature range (−55 °C to +105 °C), and a specified endurance of 2000 hours at 105 °C—providing predictable performance for volume production use.

Key Features

• Core Electrical 68 μF capacitance with ±20% tolerance at 120 Hz, rated for 25 V operation and polarized configuration.
• Low ESR & High-Frequency Performance ESR specified at 24 mΩ (20 °C / 100 kHz) with high-frequency ripple capability up to 3.6 A at 300 kHz, supporting high-rate AC currents on power rails.
• Ripple & Leakage Low-frequency ripple current rating of 360 mA at 120 Hz and leakage current specified at 850 μA (after 2 minutes at 20 °C), enabling stable long-term operation under rated voltage.
• Package & Mounting Radial lead, can-style package (φ8 × 11.5 mm) with 3.5 mm lead spacing (±0.5 mm). Supplied in bulk with no terminal forming and bag packing for production assembly.
• Reliability & Temperature Range Endurance rated to 2000 hours at 105 °C and an operating temperature range from −55 °C to +105 °C, providing defined life expectancy under elevated-temperature conditions.
• Compliance & Availability RoHS compliant and listed as mass production status under Nichicon’s RNU series.

Typical Applications

• General-purpose electronics — Suited for mainstream board-level uses where a reliable, polarized capacitor is required for energy storage and smoothing.
• High-frequency power rails — Low ESR and a 3.6 A rating at 300 kHz make it suitable for decoupling and ripple handling on high-frequency switch-mode supplies.
• Thermally demanding environments — Rated for continuous operation to 105 °C with a 2000-hour endurance specification for designs exposed to elevated temperatures.
• Volume production assemblies — Radial lead format and bulk/bag packing support automated through-hole assembly and high-volume manufacturing workflows.

Unique Advantages

• Low ESR for improved power efficiency: 24 mΩ ESR (20 °C / 100 kHz) reduces voltage drop and heat generation on high-current AC components of the circuit.
• High ripple-current capability: Rated ripple currents of 360 mA (120 Hz) and 3.6 A (300 kHz) enable effective handling of both low- and high-frequency ripple components.
• Defined high-temperature endurance: 2000 hours at 105 °C gives designers a clear specification for long-term performance under elevated temperatures.
• Compact radial can package: φ8×11.5 mm size with 3.5 mm lead spacing fits space-constrained board layouts while supporting through-hole assembly.
• Production-ready supply: Mass production status and RoHS compliance support procurement and regulatory needs for commercial product lines.
