RPS1J120MCN1GS

The RPS1J120MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for general-purpose power decoupling and bulk storage in compact electronic assemblies. As part of Nichicon’s RPS series, this device offers low ESR and high ripple-current handling in a small φ8 × 6.7 mm can-style SMD package, making it suitable for applications requiring reliable decoupling at voltages up to 63 V.

Key Features

• Conductive polymer construction — Solid electrolyte provides stable electrical characteristics and reduced ESR compared with conventional liquid electrolytic capacitors.
• Capacitance and tolerance — 12 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, suitable for power-supply filtering and decoupling.
• Rated voltage — 63 V rating for higher-voltage rail applications.
• Low ESR — ESR of 38 mΩ measured at 20°C, 100 kHz for improved high-frequency performance.
• High ripple-current capability — Rated ripple current of 150 mA at 120 Hz and 1.5 A at 300 kHz, enabling effective suppression of AC components across a wide frequency range.
• Thermal and endurance performance — Operating temperature range −55°C to 105°C with a load life of 2000 hours at 105°C.
• Leakage and dissipation — Specified leakage current of 151 µA (after 2 minutes at 20°C) and tanδ of 0.12 at 120 Hz, 20°C.
• SMD, compact can package — φ8 × 6.7 mm case (package case: Radial, Can - SMD) with embossed carrier taping and moisture-proof packing for automated assembly.
• RoHS compliant — Meets the RoHS directive as stated in the product information.

Typical Applications

• Power-supply decoupling — Local energy buffering and high-frequency noise suppression on DC power rails up to 63 V.
• Point-of-load modules — Bulk and transient current support in compact DC–DC converters and regulator outputs.
• Industrial control electronics — Filtering and energy storage in control boards operating across a wide temperature range (−55°C to 105°C).
• Communications equipment — High-frequency ripple handling for power chains in telecom and networking modules.

Unique Advantages

• Low ESR for improved transient response: 38 mΩ at 100 kHz reduces voltage ripple and improves regulator stability in high-frequency circuits.
• Wide frequency ripple capability: Specified ripple-current performance at both 120 Hz and 300 kHz supports designs that must manage both low- and high-frequency disturbances.
• Compact SMD can package: φ8 × 6.7 mm form factor balances capacitance and board space for dense assemblies while supporting automated placement and moisture-proof packing.
• High-voltage support: 63 V rating enables use on higher-voltage rails without multiple parallel components.
• Designed for elevated operating temperatures: 2000-hour endurance at 105°C provides predictable lifetime behavior in thermally demanding environments.
