RNE1C681MCN1

The RNE1C681MCN1 from Nichicon is a radial-lead conductive polymer aluminum solid electrolytic capacitor designed for general-purpose electronic assemblies. It combines high capacitance and low equivalent series resistance (ESR) in a compact radial can package, offering robust ripple-current handling and extended load life for demanding operating environments.

This part is lead-free flow soldering condition compatible and RoHS compliant (2011/65/EU, (EU)2015/863), making it suitable for modern, regulatory-compliant production processes.

Key Features

• High Capacitance — 680 µF rated capacitance to support bulk energy storage and smoothing in compact assemblies.
• 16 V Rated Voltage — Rated voltage of 16 V for low-voltage power rails and general-purpose applications.
• Low ESR — ESR of 10 mΩ measured at 100 kHz, enabling efficient power delivery and reduced dissipation.
• High Ripple Current Capability — Handles 523 mA at 120 Hz and 5.23 A at 300 kHz, supporting both low- and high-frequency ripple conditions.
• Robust Thermal Endurance — Operating temperature range from −55 °C to +105 °C with a load life rated at 2000/5000 hours at 105 °C.
• Radial Lead Package — Radial, can-style package with 3.5 mm lead spacing and compact dimensions (L: 1.15 × D: 0.8 cm) for through-hole assemblies.
• Polarized — Polarized component suitable for typical electrolytic capacitor use cases; capacitance tolerance ±20%.
• Regulatory and Assembly Compatibility — Lead-free flow soldering condition correspondence and RoHS compliance.

Typical Applications

• General-purpose electronic assemblies — Provides bulk capacitance and stable ESR for circuitry labeled under general-purpose applications.
• Power management subsystems — Useful where high ripple-current capability and low ESR are needed for smoothing and energy buffering on low-voltage rails.
• Industrial and consumer electronics — Compact radial-can format and wide operating temperature range suit a range of board-level designs that require durable electrolytic capacitance.

Unique Advantages

• High energy density in a compact package: 680 µF in a small radial can (1.15 × 0.8 cm) helps reduce board footprint while delivering substantial bulk capacitance.
• Low ESR for efficient power delivery: 10 mΩ at 100 kHz lowers power loss and thermal rise in high-current paths.
• Wide frequency ripple handling: Rated ripple currents of 523 mA at 120 Hz and 5.23 A at 300 kHz support both low- and high-frequency decoupling needs.
• Durable thermal performance: −55 °C to +105 °C operating range with a tested load life of 2000/5000 hours at 105 °C for long-term reliability.
• Production-ready solder compatibility: Radial lead type with lead-free flow soldering condition correspondence eases integration into lead-free manufacturing processes.
• Regulatory compliance: Conforms to RoHS directives (2011/65/EU, (EU)2015/863) for environmentally compliant designs.
