RHT0J681MDN1

The RHT0J681MDN1 from Nichicon is a radial-lead conductive polymer aluminum solid electrolytic capacitor rated at 6.3 V and 680 µF. It combines low equivalent series resistance and high ripple-current capability with a wide operating temperature range for general-purpose electronic designs.

Designed for demanding thermal environments, this part is specified for operation from −55°C to 125°C and carries a rated load life of 1000 hours at 125°C, making it suitable where sustained high-temperature performance is required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a rated voltage of 6.3 V with a tolerance of −20% to +20%.
• Conductive Polymer Construction — Solid electrolytic design for low tanδ (0.12 at 20°C, 120 Hz) and stable electrical characteristics.
• Low ESR — ESR of 12 mΩ measured at 20°C/100 kHz, enabling improved AC performance and thermal stability under ripple conditions.
• High Ripple Current Capability — Rated for 174 mA at 120 Hz (low frequency) and 1.74 A at 300 kHz (high frequency), supporting effective ripple handling in compact packages.
• High-Temperature Endurance — Load life specified as 1000 hours at 125°C under rated voltage, with end-of-life criteria defined for capacitance, tanδ, ESR, and leakage current.
• Compact Radial Package — φ10 × 12.5 mm can with 5.0 mm lead spacing and radial-lead mounting; available in bulk or bag packing for flexible assembly.
• Leakage Current Specification — Leakage current of 856 µA at 20°C (measured after 2 minutes), providing a defined baseline for design calculations.
• Regulatory Status — RoHS compliant.

Typical Applications

• General Purpose — For general-purpose electronic circuits requiring a polarized 680 µF, 6.3 V capacitor with high-temperature capability.
• High-Temperature Designs — Where operation up to 125°C and a 1000 h rated life are required, the RHT0J681MDN1 provides defined endurance characteristics.
• Ripple-Handling Circuits — Suited to applications that require quantified ripple performance thanks to a 12 mΩ ESR (100 kHz) and specified ripple currents at 120 Hz and 300 kHz.

Unique Advantages

• Measured Low ESR (12 mΩ) — Enables predictable AC performance and supports the specified high-frequency ripple current capability.
• Defined High-Temperature Life — 1000 hours at 125°C provides an explicit endurance metric for thermal reliability planning.
• High Ripple Current Ratings — Clear low- and high-frequency ripple current specifications (174 mA at 120 Hz; 1.74 A at 300 kHz) for margin-aware design.
• Compact Radial Form Factor — φ10 × 12.5 mm can with 5.0 mm lead spacing offers a small footprint for through-hole assemblies while maintaining capacitance density.
• Stable Dielectric Performance — tanδ of 0.12 (20°C, 120 Hz) and controlled leakage (856 µA) yield predictable behavior for circuit designers.
• Production Availability — Designated as mass production and offered in bulk or bag packing for scalable procurement and assembly.
