RPS1A121MCN1GS

The RPS1A121MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RPS series. It delivers 120 µF capacitance at a 10 V rating with low equivalent series resistance and high ripple-current capability, packaged in an 8 × 6.7 mm SMD can.

Designed for general-purpose electronic use, this part targets circuits that require compact bulk capacitance, high-frequency ripple handling, and wide operating temperature range while maintaining RoHS compliance and mass-production availability.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance at 10 V, ±20% tolerance for predictable energy storage in low-voltage designs.
• Conductive-Polymer Construction — Solid polymer electrolyte for stable electrical characteristics and improved ripple handling compared with traditional wet electrolytes.
• Low ESR & High-Frequency Performance — ESR of 30 mΩ measured at 20°C/100 kHz and a tanδ of 0.12 (20°C, 120 Hz, 10 V), enabling efficient high-frequency decoupling and power filtering.
• High Ripple Current Capability — Rated ripple current of 260 mA at 120 Hz and 2.6 A at 300 kHz, suitable for applications with significant AC or switching noise.
• Robust Thermal & Lifetime Specs — Operating temperature range −55°C to +105°C with a rated load life of 2000 hours at 105°C.
• SMD Can Package & Board Compatibility — Compact φ8 × 6.7 mm can-style SMD (package case: radial, can - SMD) with recommended land size 8.3 × 8.3 mm for straightforward PCB placement.
• Assembly & Compliance — Embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering conditions up to a 260°C peak. RoHS compliant.
• Leakage Current — Specified leakage current of 240 µA (measured after 2 minutes at 20°C), supporting predictable bias current budgets.

Typical Applications

• General-Purpose Electronics — Bulk capacitance and decoupling in low-voltage circuits where 10 V rating and 120 µF are required.
• Power Filtering and Decoupling — Low ESR and high ripple current ratings make it suitable for smoothing and decoupling in switching power stages and regulators.
• High-Frequency Ripple Management — Demonstrated performance at 100–300 kHz frequency range supports use where high-frequency ripple suppression is needed.

Unique Advantages

• Compact, high-capacity SMD solution: 120 µF in a φ8 × 6.7 mm can reduces board area while providing substantial bulk capacitance.
• Effective high-frequency performance: 30 mΩ ESR at 100 kHz and frequency-rated ripple currents enable efficient suppression of switching noise.
• Wide temperature tolerance and rated life: −55°C to +105°C operation and 2000-hour endurance at 105°C support reliable operation in demanding thermal environments.
• Manufacturing-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated assembly; compatible with 260°C lead-free reflow profiles.
• Regulatory compliance: RoHS-compliant construction supports restricted-substance requirements for commercial production.
• Predictable leakage behavior: Specified leakage current (240 µA) and polymer construction reduce uncertainty in bias-sensitive designs.
