RHS0G122MCN1GS

The RHS0G122MCN1GS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in the RHS series, specified as a surface-mount, polarized device with a rated capacitance of 1.2 mF and a rated voltage of 4 V. It is designed for general-purpose surface-mount applications that require high capacitance, low ESR and strong ripple-current capability.

Key performance attributes include low equivalent series resistance, high ripple current handling across low and high frequencies, a 2000-hour load life at 105°C, and lead-free reflow compatibility to a 260°C peak. The device is RoHS compliant.

Key Features

• Conductive polymer aluminum construction Solid electrolytic design for stabilized capacitance and reliable performance in surface-mount applications.
• High capacitance 1.2 mF (1.2 millifarads) rated capacitance for energy storage, decoupling and bulk smoothing.
• Low ESR ESR of 9 mΩ measured at 100 kHz, 20°C—minimizes AC loss and improves efficiency in high-frequency circuits.
• High ripple-current capability Rated ripple current of 540 mA at 120 Hz and 5.4 A at 300 kHz, supporting both low- and high-frequency converter loads.
• Temperature and endurance Operating range −55°C to +105°C with a specified load life of 2000 hours at 105°C under rated voltage conditions.
• Surface-mount, radial can package SMD form factor (Radial, Can - SMD) with a recommended land size of 8.3 × 8.3 mm for PCB mounting and automated assembly.
• Manufacturing and compliance Lead-free reflow soldering compatibility to a 260°C peak and compliance with RoHS (2011/65/EU, (EU)2015/863).
• Polarized with standard tolerance Polarized device with capacitance tolerance of −20% to +20% at 120 Hz, 20°C.

Typical Applications

• General Purpose Intended for general-purpose surface-mount applications that require high capacitance, low ESR and robust ripple-current handling.

Unique Advantages

• Low AC loss: 9 mΩ ESR at 100 kHz reduces dissipative losses in high-frequency circuits, improving efficiency and thermal performance.
• Broad ripple capability: Rated ripple current values of 540 mA (120 Hz) and 5.4 A (300 kHz) provide flexibility across switching frequencies.
• High-temperature endurance: 2000 hours at 105°C load life supports designs that operate under sustained elevated temperatures.
• Surface-mount packaging: Radial can SMD package with a defined land pattern (8.3 × 8.3 mm) for automated assembly and compact PCB layouts.
• Assembly-ready: Compatibility with lead-free reflow to a 260°C peak simplifies integration into modern, Pb-free manufacturing flows.
• Regulatory compliance: RoHS compliance supports use in products targeting restricted-substance requirements.
