RDS1A121MCNAHFGS

The RDS1A121MCNAHFGS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount can package. It delivers 120 µF at 10 V with low ESR and elevated ripple-current capability for compact power and filtering circuits.

Designed for elevated-temperature endurance, this SMD capacitor supports a rated operating range of −55°C to +125°C and a load life of 3000 hours at 125°C. It is compatible with lead-free reflow soldering conditions (260°C peak) and is RoHS compliant.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a rated voltage of 10 V and tolerance of −20% to +20%.
• Conductive Polymer Construction — Solid polymer aluminum electrolytic design for stable electrical characteristics under load.
• Low ESR — ESR of 18 mΩ measured at 100 kHz, 20°C, supporting efficient high-frequency performance.
• High Ripple Current — Rated ripple current up to 2.45 A at 300 kHz (and 245 mA at 120 Hz), enabling robust handling of AC stress in power stages.
• High-Temperature Endurance — Load life specified at 3000 hours when operated at 125°C and rated voltage.
• Surface-Mount Can Package — Radial SMD can package with dimensions L: 6.7 × D: 8 mm and recommended land size L: 8.3 × W: 8.3 mm for PCB mounting.
• Lead-Free Reflow & RoHS — Compatible with 260°C peak lead-free reflow soldering conditions and compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Surface-mount power modules — Provides bulk capacitance and ripple handling for compact DC power stages where an SMD can is required.
• High-frequency power filtering — Low ESR (18 mΩ at 100 kHz) and rated ripple current up to 2.45 A at 300 kHz support filtering in high-frequency circuits.
• Elevated-temperature environments — Rated for continuous operation from −55°C to +125°C with a 3000-hour life at 125°C for designs requiring extended high-temperature reliability.

Unique Advantages

• High capacitance in a compact SMD can — 120 µF in an 8 × 6.7 mm case size provides significant capacitance density for space-constrained designs.
• Robust ripple handling — High-frequency ripple rating (2.45 A at 300 kHz) reduces thermal stress and improves performance in switching power applications.
• Low ESR for improved efficiency — 18 mΩ ESR at 100 kHz lowers conduction losses and supports stable voltage behavior under dynamic loads.
• Long high-temperature life — 3000 hours at 125°C offers predictable end-of-life behavior for elevated-temperature applications.
• Assembly-ready with lead-free reflow — Compatible with 260°C peak lead-free reflow processes, simplifying surface-mount assembly flows.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
