• Electrical Ratings 680 µF capacitance with ±20% tolerance at 20°C/120 Hz and a 10 V rated voltage for mid-voltage power rails.
• Thermal and Endurance Performance Operating range −55°C to 105°C and life of 2000 hours at 105°C, suitable for sustained elevated-temperature operation.
• Package and Mounting Radial lead can (φ10×12.5 mm) with 5 mm lead spacing (±0.5 mm) for through-hole mounting; available in bulk (no terminal forming) or bag packing.
• Leakage and Dissipation Specified leakage current of 1360 µA and tan δ (DF) of 0.1 measured at 20°C/120 Hz, allowing predictable behavior in DC bias conditions.
• RoHS Compliant Meets RoHS requirements for restricted substances.

Typical Applications

• Power supply decoupling and smoothing — Low ESR (7 mΩ) and high ripple current handling make this capacitor suitable for stabilizing mid-voltage rails and reducing output ripple.
• DC‑DC converter output filtering — Compact φ10×12.5 mm package with high-frequency ripple capability (6.1 A at 300 kHz) supports modern switching regulator outputs.
• General-purpose electronics — The RR71A681MDN1’s wide temperature range (−55°C to 105°C) and 2000-hour endurance at 105°C suit a variety of consumer and industrial circuits requiring reliable bulk capacitance.

Unique Advantages

• Measured low ESR for lower losses — 7 mΩ at 20°C/100 kHz reduces I²R heating and improves regulator efficiency.
• Strong high-frequency performance — Rated 6.1 A ripple at 300 kHz supports fast-switching power stages and high-frequency decoupling needs.
• Compact, through-hole form factor — φ10×12.5 mm radial lead can with 5 mm lead spacing fits space-constrained PCB layouts while retaining robust mounting.
• Robust thermal endurance — 2000-hour life at 105°C and −55°C to 105°C operating range provide predictable long-term behavior under elevated temperatures.
• Predictable leakage and dissipation — Specified leakage current (1360 µA) and tan δ (0.1) allow accurate power budgeting and thermal design.
• Production-ready packaging — Available in bulk (no terminal forming) or bag packing for easy integration into assembly and procurement workflows.
