RPS0G122MCN1GS

The RPS0G122MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount can package, offering 1200 µF capacitance with a 4 V rated voltage. It combines low ESR and high ripple-current capability in a compact φ10 × 12.4 mm SMD package for space-constrained power designs.

Designed for general-purpose power applications, the device delivers measurable benefits for power-rail decoupling and high-frequency filtering through low equivalent series resistance (12 mΩ at 100 kHz) and rated ripple currents up to 5.5 A at high frequency. It supports elevated operating conditions with a −55 °C to 105 °C temperature range and a 2000-hour endurance at 105 °C.

Key Features

• Electrical Capacity — 1.2 mF (1200 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20 °C for predictable bulk energy storage.
• Low Loss / Low ESR — tanδ 0.12 (20 °C, 120 Hz) and ESR 12 mΩ measured at 20 °C / 100 kHz to minimize voltage drop and power loss in high-frequency circuits.
• High Ripple Current — Rated ripple current of 550 mA at 120 Hz and 5.5 A at 300 kHz, enabling effective smoothing for switching supplies and power rails.
• Thermal and Endurance — Operates from −55 °C to 105 °C with a rated life of 2000 hours at 105 °C, supporting sustained elevated-temperature operation.
• Surface-Mount Can Package — Radial, can-style SMD (φ10 × 12.4 mm) with surface mount land size L: 10.3 mm × W: 10.3 mm and a seated height of 12.4 mm for compact PCB integration.
• Assembly-Ready Packaging — Supplied on embossed carrier tape with moisture-proof packing and compatible with lead-free reflow soldering conditions (260 °C peak).
• Environmental Compliance — RoHS compliant for use in regulated designs.

Typical Applications

• Power-rail decoupling — Low ESR and high ripple capability make it suitable for smoothing and stabilizing supply rails in power conversion circuits.
• Switching regulator input filtering — High-frequency ripple current rating and ESR measured at 100 kHz support filtering at switching frequencies.
• Compact SMD power modules — The φ10 × 12.4 mm surface-mount can provides bulk capacitance in tight board layouts where axial or larger cans are impractical.

Unique Advantages

• Low ESR for improved power efficiency: 12 mΩ ESR at 100 kHz reduces I²R losses and helps maintain voltage stability at high switching frequencies.
• High ripple-current handling: 5.5 A at high frequency and 550 mA at 120 Hz enable robust filtering for both low- and high-frequency ripple components.
• Compact, assembly-ready form factor: φ10 × 12.4 mm SMD can with embossed carrier taping and moisture-proof packing simplifies automated placement and reflow processing.
• Wide temperature range and rated life: −55 °C to 105 °C operating range and 2000 hours endurance at 105 °C support designs exposed to elevated ambient temperatures.
• Reflow-compatible and RoHS compliant: Supports lead-free reflow peak of 260 °C and meets RoHS requirements for streamlined manufacturing and compliance.
