RR70E681MDN1

The RR70E681MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, part of Nichicon’s RR7 series. It delivers ultra-low ESR and high ripple current capability in a compact φ8×11.5 mm package for general-purpose electronic designs.

Engineered for demanding temperature and ripple environments, this 680 µF, 2.5 V polarized capacitor provides a combination of low impedance, measurable leakage control and a 2000-hour endurance rating at 105°C.

Key Features

• Dielectric / Electrolyte Conductive polymer solid electrolyte for low ESR and stable performance.
• Low Equivalent Series Resistance (ESR) 7 mΩ specified at 20°C / 100 kHz, enabling high-frequency decoupling and low loss under AC stress.
• High Ripple Current Handling Rated ripple current 5.6 A (105°C / 100 kHz); frequency coefficient data yields 560 mA at 120 Hz and unity at higher RF frequencies.
• Capacitance and Tolerance 680 µF with ±20% tolerance at 120 Hz, 20°C.
• Thermal and Endurance Operating temperature range −55°C to +105°C with a rated load life of 2000 hours at 105°C.
• Leakage and Loss Leakage current specified at 425 µA (measured at 20°C after 2 minutes); tan δ of 0.08 at 120 Hz, 20°C.
• Form Factor Radial lead, φ8×11.5 mm can with 3.5 mm lead spacing (±0.5 mm tolerance); available in bulk or bag packing.
• Regulatory RoHS compliant.

Typical Applications

• General-purpose electronic equipment Suitable for designs requiring a compact, low-ESR polarized capacitor at 2.5 V.
• Power filtering and decoupling Low ESR and high ripple current specifications support smoothing and decoupling roles in power rails within general-purpose designs.
• Compact board-level implementations Radial lead package (φ8×11.5 mm) and 3.5 mm lead spacing for through-hole mounting in space-constrained assemblies.

Unique Advantages

• Ultra-low ESR: 7 mΩ at 20°C/100 kHz reduces AC losses and supports stable voltage under ripple.
• High ripple capacity: 5.6 A rated ripple current at 100 kHz (105°C) enables reliable operation under significant AC stress.
• Compact radial package: φ8×11.5 mm can with 3.5 mm lead spacing delivers dense board-level placement while maintaining robust filtering capability.
• Wide operating range: −55°C to +105°C supports deployment across varied thermal environments common in general-purpose electronics.
• Endurance-rated: 2000 hours at 105°C provides a defined lifetime metric for thermal and operational planning.
• RoHS-compliant manufacturing: Meets lead-restriction requirements for regulated markets.
