UPJ1V220MDD

The UPJ1V220MDD is a radial aluminum electrolytic capacitor in Nichicon’s UPJ series, rated 22 µF at 35 V with a ±20% tolerance. Designed for low impedance performance and general-purpose power applications, it is especially well suited for switching power supply filtering and local decoupling where a compact, through-hole radial package is required.

Key Features

• Electrical Performance  22 µF capacitance at 35 V with ±20% tolerance, providing stable bulk capacitance for power-rail smoothing.
• Low Loss and Leakage  tanδ of 0.12 (max) at 35 V and a measured leakage current of 23.1 µA, minimizing dissipation and standby current.
• Ripple Current Handling  Rated ripple currents of 42.5 mA at 120 Hz and 85 mA at 200 kHz to support AC ripple in switching environments.
• Temperature and Lifetime  Operating range from −55°C to +105°C with a rated life of 2000 hours at 105°C, supporting sustained operation in elevated-temperature designs.
• Mechanical and Mounting  Compact radial can package (φ5 × 11 mm) with 2 mm lead spacing and radial lead mounting for easy through-hole assembly.
• Compliance  RoHS compliant for designs requiring environmental directive conformance.

Typical Applications

• Switching power supplies  Low impedance characteristics make the UPJ1V220MDD suitable for output filtering and smoothing in switching regulator designs.
• General-purpose power filtering  Compact radial form factor and stable capacitance support local decoupling and bulk storage on power rails.
• Through-hole power modules  Radial lead package with 2 mm lead spacing simplifies mounting and replacement in through-hole assemblies.

Unique Advantages

• Low-impedance design  Reduces AC ripple and voltage fluctuation on power rails, improving regulator stability where compact electrolytic capacitance is needed.
• Measured low leakage  Leakage current of 23.1 µA helps minimize standby current and unwanted discharge paths in low-power states.
• Compact radial package  φ5 × 11 mm can size with 2 mm lead spacing allows space-efficient placement on through-hole PCBs.
• Broad operating temperature  Rated from −55°C to +105°C to accommodate designs exposed to a wide thermal range.
• Clear ripple specifications  Specified ripple currents at both low and high frequencies help designers validate thermal and ripple handling in switching applications.
• RoHS compliant  Meets environmental directive requirements for regulated substances.

Why Choose UPJ1V220MDD?

The UPJ1V220MDD combines a compact radial can package with low-impedance electrical characteristics and clearly defined ripple, loss, and leakage specifications. Its −55°C to +105°C operating range and 2000-hour rating at 105°C make it a practical choice for designers who need reliable electrolytic capacitance in space-constrained, through-hole applications.

This part is ideal for engineers specifying power-supply output filters, local decoupling, and general-purpose smoothing where a small, RoHS-compliant aluminum electrolytic with documented ripple and leakage characteristics is required.
