UPM1H121MPD6

The UPM1H121MPD6 is an aluminum electrolytic capacitor from Nichicon’s UPM series, offering a 120 µF capacitance at a 50 V rating in a radial lead can package. It delivers low impedance and long-term reliability in a compact φ10 × 16 mm form factor with 5 mm lead spacing.

Designed for demanding temperature and duty cycles, this polarized capacitor supports operation from −55 °C to +105 °C and a rated lifetime of 5000 hours at 105 °C, making it suitable for systems that require sustained ripple handling and thermal endurance.

Key Features

• Electrical Performance 120 µF nominal capacitance with ±20% tolerance and a 50 V rated voltage for bulk energy storage and smoothing applications.
• Low Impedance Specified impedance of 130 mΩ to improve ripple handling and reduce voltage drop under load.
• Ripple Current Ratings Rated ripple current of 270.3 mA at 120 Hz and 510 mA at 200 kHz for effective AC ripple attenuation across low- and high-frequency ranges.
• Thermal and Reliability Wide operating range from −55 °C to +105 °C and a guaranteed lifetime of 5000 hours at 105 °C to support long-term high-temperature operation.
• Package & Mounting Radial lead can, φ10 × 16 mm (1.6 cm × 1.0 cm) with 5 mm lead spacing; supplied in bulk (no terminal forming) / bag packing for production assembly.
• Automotive-Grade Qualification AEC‑Q200 qualified, enabling use in applications that require automotive-grade component qualification.
• Compliance RoHS compliant and polarized construction for correct DC application.

Typical Applications

• Automotive electronics — Suited for automotive modules and control units where AEC‑Q200 qualification, extended temperature range, and long life at 105 °C are required.
• Power supply filtering — Low impedance and rated ripple currents make it appropriate for bulk filtering, smoothing and decoupling in power rails.
• High-temperature environments — Operation to +105 °C and a 5000-hour life rating support use in thermally demanding assemblies and industrial electronics.

Unique Advantages

• Extended high-temperature life: 5000 hours at 105 °C provides predictable endurance for long-term deployments.
