RNL1C122MDS4

The RNL1C122MDS4 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can designed for general-purpose electronic applications. It delivers high capacitance (1.2 mF) and low ESR together with high ripple current capability in a compact radial package.

Engineered for reliability across a wide temperature range (−55°C to +105°C) and offered with load-life ratings of 2000 / 5000 hours at 105°C, this part is suitable where stable bulk capacitance, low losses and long-term thermal endurance are required. It is RoHS compliant and compatible with lead-free flow soldering conditions.

Key Features

• Capacitance & Voltage — 1.2 mF rated capacitance at 16 V, with capacitance tolerance of −20% to +20%.
• Low ESR — ESR of 8 mΩ measured at 100 kHz, supporting improved efficiency and reduced heat generation in high-frequency applications.
• High Ripple Current — Rated ripple current of 770 mA at 120 Hz and 7.7 A at 300 kHz, enabling handling of substantial AC ripple and switching currents.
• Thermal & Endurance — Operating temperature range from −55°C to +105°C with specified load life of 2000 / 5000 hours at 105°C for long-term operation under elevated temperature stress.
• Radial Lead Package — Radial, can-style package with 5 mm lead spacing for through-hole mounting and reliable mechanical attachment.
• Polarized — Polar capacitor type suited for DC circuits requiring polarity-aware bulk capacitance.
• Regulatory & Assembly — RoHS compliant and compatible with lead-free flow soldering conditions for modern manufacturing and regulatory requirements.

Typical Applications

• General-purpose electronics — Bulk energy storage and decoupling where a polarized 1.2 mF, 16 V capacitor with low ESR and high ripple tolerance is required.
• Power conversion stages — Use where high ripple current capability and low loss at switching frequencies improve stability and thermal performance.
• Industrial equipment — Suitable for circuits operating across −55°C to +105°C that need long-term endurance at elevated temperatures.

Unique Advantages

• High capacitance in a compact radial can: 1.2 mF of capacitance provides substantial bulk energy storage while keeping a through-hole mounting footprint.
• Low-loss operation: 8 mΩ ESR at 100 kHz reduces I²R losses and improves efficiency in high-frequency and switching environments.
• High ripple handling: Rated ripple currents up to 7.7 A at 300 kHz support demanding ripple and switching conditions.
• Designed for elevated-temperature endurance: Load-life ratings of 2000 / 5000 hours at 105°C provide predictable life performance in hot environments.
• Manufacturing-friendly: Radial lead form with compatibility for lead-free flow soldering streamlines assembly on through-hole PCBs.
• Regulatory compliance: RoHS conformity supports use in regulated production environments.
