RNE1C681MCNASQ

The RNE1C681MCNASQ is a conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RNE series, offered in a radial lead, can-style package. It delivers high capacitance and low equivalent series resistance (ESR) in a compact radial format for general-purpose electronic use.

Designed for applications that require high ripple handling and long-term stability, this part provides a combination of 680 µF capacitance, a 16 V rating, and a rated lifetime of 5000 hours at 105°C, with RoHS compliance for environmental requirements.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a 16 V rated voltage; capacitance tolerance is ±20% at 120 Hz, 20°C.
• Conductive Polymer Electrolyte — Solid conductive polymer construction as specified for the RNE series, offering low ESR performance.
• Low ESR — 10 mΩ equivalent series resistance specified at 100 kHz, 20°C, supporting efficient high-frequency performance.
• High Ripple Current — Rated ripple current of 523 mA at 120 Hz and 5.23 A at 300 kHz; frequency coefficients are provided across 120 Hz–300 kHz (0.10 @120 Hz, 0.45 @1 kHz, 0.50 @10 kHz, 1.00 @100 kHz, 1.00 @300 kHz).
• Thermal Endurance — Load life rated at 5000 hours at 105°C, with category temperature range from −55°C to +105°C.
• Radial Lead Package — Radial, can-style package with 3.5 mm lead spacing; compact dimensions L: 1.15 cm × D: 0.8 cm and polarized construction.
• Compliance — Lead-free flow soldering condition correspondence and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — Smoothing and decoupling on power rails where high capacitance and low ESR improve transient response and ripple attenuation.
• High-ripple power stages — Local bulk capacitance in circuits that experience significant ripple current up to the specified high-frequency ratings.
• Embedded and industrial electronics — General-purpose energy storage for boards and modules operating across −55°C to +105°C with long-term load life requirements.

Unique Advantages

• High stored energy in a compact radial package: 680 µF at 16 V provides substantial charge capacity in a small can-style footprint (1.15 × 0.8 cm).
• Low ESR for improved efficiency: 10 mΩ at 100 kHz reduces resistive losses and heat generation at high switching frequencies.
• High-frequency ripple capability: Rated ripple currents up to 5.23 A at 300 kHz with published frequency coefficients to aid design margining.
• Proven thermal endurance: 5000-hour load life at 105°C supports applications requiring sustained elevated-temperature operation.
• Regulatory readiness: Lead-free flow soldering correspondence and RoHS compliance meet common environmental and assembly requirements.
