RR70G122MDN1

The RR70G122MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, rated 1200 µF at 4 V with polarization. Designed for general-purpose electronic applications, it delivers ultra-low ESR and high ripple-current handling for demanding power-decoupling and smoothing tasks.

Key built-in attributes include a wide operating temperature range (−55°C to +105°C), a 2000-hour load life at 105°C, and RoHS compliance, making it suitable where thermal endurance and reliable high-frequency performance are required.

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance at a 4 V rated voltage with tolerance −20% to +20%, providing substantial bulk capacitance in a compact radial package.
• Ultra Low ESR — ESR specified at 7 mΩ measured at 100 kHz, 20°C, enabling efficient high-frequency performance and reduced loss.
• High Ripple Current — Rated ripple current of 6.1 A at 100–300 kHz (6.1 A at 300 kHz equivalently) and 610 mA at 120 Hz, supporting high-frequency power stages and switching supplies.
• Thermal Endurance & Lifetime — Rated for operation from −55°C to +105°C with a specified load life of 2000 hours at 105°C.
• Radial Lead, Through-Hole Mounting — Radial lead, can-style package with 5 mm lead spacing and compatibility with lead-free flow soldering conditions.
• Compact Case Size — Case dimensions φD×L = 10 × 12.5 mm, with overall size L: 1.25 cm × D: 1.0 cm, enabling space-efficient placement on through-hole PCBs.
• Polarized, General Purpose — Polarized component intended for general-purpose use where conductive polymer solid-electrolytic characteristics are desired.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Power supply filtering — Bulk smoothing and decoupling in low-voltage power rails where 1200 µF and low ESR reduce output ripple and voltage excursions.
• High-frequency switching stages — Supports switching converters and regulators with high ripple-current capability (up to 6.1 A at high frequency) and low ESR at 100 kHz.
• General-purpose electronic assemblies — Through-hole radial form factor suits prototyping, repair, and designs that require robust, serviceable capacitors with a 2000-hour life at 105°C.

Unique Advantages

• Low-loss operation: 7 mΩ ESR at 100 kHz reduces I²R losses and heating in high-current applications.
• High ripple handling: Rated ripple current up to 6.1 A at high frequency supports demanding DC/DC outputs and switching nodes.
• Thermal reliability: Specified for −55°C to +105°C and 2000 hours at 105°C, offering predictable performance under elevated temperature stress.
• Space-efficient through-hole package: 10 × 12.5 mm can provides large capacitance in a compact radial form for PCB layouts that require through-hole components.
• Manufacturing-ready: Radial lead design corresponds to lead-free flow soldering conditions for production environments.
• RoHS conformity: Compliant with RoHS directives, simplifying regulatory integration into assemblies.
