RNU0G122MDN1

The RNU0G122MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, offering 1,200 µF capacitance at a 4 V rating. It combines high capacitance and low ESR with a compact φ8 × 11.5 mm package and is intended for general-purpose electronic applications.

Designed for applications that require high ripple tolerance and thermal endurance, this part delivers measurable performance: 7 mΩ ESR (20°C/100 kHz), rated ripple currents up to 5.7 A (300 kHz), and an operating range from −55°C to 105°C with a rated life of 2,000 hours at 105°C.

Key Features

• Capacitance & Voltage — 1,200 µF nominal capacitance with a 4 V rated voltage and ±20% tolerance for bulk energy storage in compact radial form.
• Conductive Polymer Electrolyte — Solid electrolyte construction for low ESR and stable high-frequency performance; tan δ of 0.08 (20°C, 120 Hz) for predictable loss characteristics.
• Low ESR & High Ripple Capability — ESR of 7 mΩ (20°C/100 kHz) and rated ripple currents of 570 mA at 120 Hz and 5.7 A at 300 kHz support high ripple and fast transient conditions.
• Thermal Endurance — Operating temperature −55°C to 105°C with a life rating of 2,000 hours at 105°C, suitable for sustained elevated-temperature operation.
• Leakage Current — Specified leakage current of 960 µA (after 2 minutes at 20°C), enabling predictable bias behavior in power circuits.
• Radial Lead Package & Mechanical — φ8 × 11.5 mm can size (0.8 × 1.15 cm), 3.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• RoHS Compliant — Conforms to RoHS requirements for environmentally restricted substances.

Typical Applications

• General-purpose power circuits — Provides bulk capacitance and low ESR in power supply designs and energy storage roles where compact radial can parts are preferred.
• High-ripple power stages — Rated high-frequency ripple current (5.7 A at 300 kHz) supports applications with significant AC ripple or fast switching transients.
• Temperature-challenged environments — With an operating range from −55°C to 105°C and 2,000 h life at 105°C, suitable for designs requiring sustained elevated-temperature performance.

Unique Advantages

• High capacitance in a compact footprint: 1,200 µF in a φ8 × 11.5 mm package reduces board area compared with larger cans for the same capacitance value.
• Low ESR for improved efficiency: 7 mΩ (20°C/100 kHz) ESR helps minimize power loss and heat generation in high-current circuits.
• Rated ripple performance across frequencies: Specified ripple currents at both low and high frequency (570 mA at 120 Hz and 5.7 A at 300 kHz) support a wide range of switching and filtering duties.
• Wide temperature range and defined life: −55°C to 105°C operation with a 2,000-hour endurance at 105°C gives predictable lifetime behavior under thermal stress.
• Through-hole mounting convenience: Radial lead can and standard 3.5 mm lead spacing simplify prototyping and replacement in legacy and industrial designs.
• RoHS compliance: Meets environmental substance restrictions for global product requirements.
