RNL1E681MDSBSQ

The RNL1E681MDSBSQ is a Nichicon RNL series conductive polymer aluminum solid electrolytic capacitor in a radial lead can. It delivers 680 µF at 25 V with low ESR and rated ripple capability for general-purpose power electronics. Designed for applications that require high capacitance density, high-frequency ripple handling and endurance in a compact φ10×16 mm package, it supports demanding thermal and ripple environments.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a 25 V rated voltage with ±20% tolerance, suitable for bulk smoothing and energy storage on power rails.
• Low ESR & High-Frequency Performance — ESR of 10 mΩ measured at 20°C/100 kHz and tanδ of 0.12 (20°C, 120 Hz) for reduced loss and improved high-frequency response.
• High Ripple Current Capability — Low-frequency ripple current of 580 mA (120 Hz) and high-frequency ripple current of 5.8 A (300 kHz) to support switching regulators and high-speed power stages.
• Thermal Range & Endurance — Rated for operation from −55°C to 105°C with a life/endurance rating of 5000 hours at 105°C.
• Radial Lead Mechanical Package — φ10×16 mm can with 5.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing and produced in mass-production quantities.
• RoHS Compliant & Soldering — Compliant with the RoHS directive; radial lead type corresponds to lead-free flow soldering conditions.

Typical Applications

• Power supply bulk smoothing — Provides bulk capacitance and energy reserve on 25 V rails to reduce voltage ripple in power supplies and adapters.
• DC–DC converter output filtering — Low ESR and high ripple capability help stabilize fast-switching converters and reduce output ripple at kHz–100 kHz frequencies.
• Communications and industrial electronics — Compact φ10×16 mm radial can fits space-constrained boards that require long-life capacitors with wide temperature tolerance.
• General-purpose electronic equipment — Suitable for consumer, industrial and infrastructure equipment that call for reliable bulk capacitance and endurance.

Unique Advantages

• High capacitance in a compact can — 680 µF in a φ10×16 mm package saves board space while providing substantial charge storage for power rails.
• Low ESR at high frequency — 10 mΩ at 100 kHz reduces I²R losses and supports efficient operation of high-frequency power stages.
• Designed for high ripple environments — Rated ripple currents of 580 mA (120 Hz) and 5.8 A (300 kHz) accommodate both low- and high-frequency ripple stress.
• Wide temperature and long life — −55°C to 105°C operating range and 5000 h endurance at 105°C provide predictable performance in elevated-temperature applications.
• Production-ready packaging — Available in bulk (no terminal forming) or bag packing and listed as mass production, simplifying procurement and assembly planning.
• Regulatory and process readiness — RoHS compliance and compatibility with lead-free flow soldering support modern manufacturing and regulatory requirements.
