RNE0J122MDN1

The RNE0J122MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, rated 1200 µF at 6.3 V. It combines high capacitance with low ESR and high ripple-current capability in a compact φ8×9 mm package.

Engineered for general-purpose electronic applications, the device supports operation from −55°C to 105°C and offers a load life endurance of 2000 hours at 105°C, making it suitable for designs where high capacitance, low loss and sustained ripple performance are required.

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance at a rated voltage of 6.3 V with a tolerance of −20% to +20%.
• Low Loss (tan δ) — tanδ = 0.08 measured at 20°C, 120 Hz, supporting stable performance in AC conditions.
• Very Low ESR — ESR of 10 mΩ measured at 20°C/100 kHz, reducing heat generation and improving high-frequency performance.
• High Ripple Current Capability — Rated ripple current 570 mA at 120 Hz and 5.7 A at 300 kHz (frequency coefficient table in datasheet supports high-frequency use).
• Leakage Current — Specified leakage current of 1512 µA (measured at 20°C after 2 minutes under rated voltage conditions).
• Thermal & Endurance — Operating temperature range −55°C to 105°C with an endurance (load life) of 2000 hours at 105°C.
• Package & Mounting — Radial lead can, case size φ8×9 mm, lead spacing 3.5 mm (±0.5 mm); offered in bulk (no terminal forming) or bag packing.
• Environment — RoHS compliant and available in mass-production quantities.

Typical Applications

• General Power Supply Filtering — High capacitance and low ESR make this part suitable for bulk smoothing and energy storage in general-purpose power supplies.
• High-Frequency Decoupling — Low ESR at 100 kHz and strong ripple-current rating support decoupling and noise suppression in circuits with high-frequency switching components.
• Compact Electronic Modules — Small φ8×9 mm footprint provides substantial capacitance in space-constrained assemblies where sustained ripple handling is required.

Unique Advantages

• High Capacitance in a Small Can — 1200 µF in a φ8×9 mm package delivers significant energy density for compact designs.
• Low ESR for Improved Efficiency — 10 mΩ ESR at 100 kHz reduces conduction losses and heat rise under high-frequency load.
• Robust Ripple Handling — Rated ripple current up to 5.7 A at high frequency supports demanding switching environments.
• Wide Temperature Range and Defined Endurance — −55°C to 105°C operating range with 2000 hours life at 105°C provides predictable long-term behavior under thermal stress.
• Production-Ready Availability — RoHS-compliant and in mass production for reliable supply and integration into commercial manufacturing flows.
