UPJ1C121MED

The UPJ1C121MED is an aluminum electrolytic capacitor in a radial lead can, rated 120µF at 16V with ±20% tolerance. Engineered as a low-impedance device for switching power supplies and general-purpose power applications, it delivers stable performance across a wide operating range.

Compact and RoHS compliant, this capacitor provides defined ripple-current capability and a specified lifetime at elevated temperature, making it suitable for embedded power designs that require reliable, through-hole electrolytic solutions.

Key Features

• Core Electrical Specs — 120µF capacitance at 16V with ±20% tolerance, polarized for DC power applications.
• Low Impedance Performance — Specified as low impedance for switching power supplies; frequency-specific ripple ratings are 103.3 mA at 120 Hz and 195 mA at 200 kHz, enabling effective ripple handling in power circuits.
• Temperature & Reliability — Rated operating temperature from −55°C to +105°C; part-level lifetime specified as 2000 hours at 105°C. Series documentation also notes extended load-life options up to 5000 hours at +105°C for certain case sizes.
• Package & Mechanical — Radial lead, can-style package with 2.5 mm lead spacing and dimensions L: 1.1 × D: 0.63 cm for compact through-hole mounting.
• Compliance — RoHS compliant, meeting the referenced RoHS directive requirements.

Typical Applications

• Switching Power Supplies — Designed specifically for use in switching power supplies where low impedance and controlled ripple handling are required.
• General-Purpose Power Circuits — Suitable for general-purpose DC power applications that require polarized electrolytic capacitance within the specified voltage and temperature range.
• Through-Hole Power Modules — Compact radial lead form factor and 2.5 mm lead spacing simplify integration into through-hole power assemblies and repairable designs.

Unique Advantages

• Low-Impedance Design: Optimized for switching power environments to reduce voltage ripple and improve regulation performance.
• Frequency-Qualified Ripple Ratings: Published ripple-current values at both low and high frequencies (103.3 mA at 120 Hz, 195 mA at 200 kHz) allow designers to match the part to their switching frequencies.
• Compact Through-Hole Package: Small can dimensions (L: 1.1 × D: 0.63 cm) and 2.5 mm lead spacing save board area while retaining robust mechanical mounting.
• Wide Temperature Range: Operates from −55°C to +105°C, supporting designs that experience broad ambient and internal temperature conditions.
• RoHS Compliance: Meets RoHS requirements for environmental compliance and regulatory alignment.
