RL80J681MDN1

The RL80J681MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial lead can (φ8×8 mm). Designed for general-purpose electronic applications, it delivers high ripple-handling capability and ultra-low ESR in a compact package.

Its combination of 680 μF capacitance, 6.3 V rating and wide operating temperature (-55°C to 105°C) targets compact power decoupling and bulk energy storage where low loss and high-frequency performance matter.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 6.3 V and capacitance tolerance of -20% to +20% (at 120 Hz, 20°C).
• Conductive Polymer Construction — Solid polymer electrolyte offering ultra-low ESR and high ripple current capability compared with conventional electrolytics.
• Low ESR & High Ripple Capacity — ESR of 8 mΩ (measured at 20°C / 100 kHz) with rated ripple currents of 570 mA at 120 Hz and 5.7 A at 300 kHz, enabling effective high-frequency filtering and bulk decoupling.
• Loss Performance — tanδ (loss tangent) of 0.12 measured at 20°C, 120 Hz for predictable dissipation behavior in AC conditions.
• Thermal & Endurance — Rated for operation from -55°C to 105°C with a specified endurance (load life) of 2000 hours at 105°C.
• Compact Radial Package — Low-profile φ8×8 mm can with radial leads and 3.5 mm lead spacing (±0.5 mm), packaged in bulk or bag packing for assembly flexibility.
• Leakage Current — Specified leakage current of 856 µA (measured per datasheet conditioning procedures), supporting predictable standby loss behavior.
• RoHS Compliance — Compliant with RoHS directives.

Typical Applications

• Power supply decoupling — Low ESR and high HF ripple capability make this capacitor suitable for smoothing and decoupling on point-of-load converters and switching regulators.
• High-frequency power modules — Compact φ8×8 mm size with strong high-frequency ripple rating supports local energy buffering in compact power stages and DC–DC modules.
• Industrial and instrumentation electronics — Wide operating temperature range (-55°C to 105°C) and 2000 h endurance at 105°C suit demanding environmental conditions and continuous-operation designs.

Unique Advantages

• Ultra-low ESR for improved efficiency: 8 mΩ ESR at 20°C / 100 kHz reduces conduction losses and improves regulator stability and transient response.
• High high-frequency ripple capability: 5.7 A ripple current at 300 kHz enables effective suppression of switching noise in compact assemblies.
• Compact, low-profile footprint: φ8×8 mm can and radial lead configuration deliver high capacitance density for space-constrained PCBs.
• Robust thermal range and endurance: -55°C to 105°C operation and 2000-hour load life at 105°C support long-term reliability in continuous-use systems.
• Predictable loss and leakage behavior: Specified tanδ (0.12 at 20°C/120 Hz) and measured leakage current support accurate thermal and power-loss budgeting.
• Assembly flexibility: Radial lead format with 3.5 mm lead spacing and bulk/bag packing options ease handling and through-hole assembly processes.
