UPJ0J121MDD

The UPJ0J121MDD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPJ series optimized for low-impedance, general-purpose power applications. It delivers 120 µF capacitance at a 6.3 V rating in a compact φ5 × 11 mm can with 2 mm lead spacing.

This part is targeted at switching power supplies and other through-hole power designs that require compact bulk capacitance, measurable ripple handling, and a broad operating temperature range from −55°C to 105°C. Product status: End of Life.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance at a rated voltage of 6.3 V with ±20% tolerance for general-purpose decoupling and bulk storage.
• Low Impedance Performance — UPJ series design noted for low impedance characteristics suitable for switching power supplies and high-frequency ripple environments.
• Ripple Current Capability — Rated ripple current of 60.95 mA at 120 Hz and 115 mA at 200 kHz to support common power conversion frequencies.
• Electrical Loss — Specified tangent of loss angle (tan δ) of 0.22 at 6.3 V, helping to predict dissipation under AC stress.
• Leakage Current — Low leakage current specified at 22.68 µA, supporting low-standby-loss designs.
• Robust Temperature & Lifetime — Operating range −55°C to +105°C with a rated load life of 2000 hours at 105°C for reliability in elevated-temperature use.
• Package & Mounting — Radial lead, can-style package (φ5 × 11 mm) with 2 mm lead spacing for through-hole assembly and straightforward PCB layout.
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and measurable ripple handling improve voltage stability.
• General Power Decoupling — Local energy storage in through-hole boards and power modules for embedded systems and industrial controls.
• Consumer and Industrial Electronics — Compact bulk capacitance for small-form-factor devices that operate across −55°C to +105°C.

Unique Advantages

• Compact Bulk Capacitance: 120 µF in a φ5 × 11 mm can provides substantial capacitance in a small footprint for dense PCB layouts.
• Designed for Switching Environments: Low-impedance UPJ series construction and rated ripple currents (60.95 mA @120 Hz, 115 mA @200 kHz) target switching power supply use.
• Predictable Loss and Leakage: Known tan δ (0.22) and measured leakage (22.68 µA) make thermal and standby-loss budgeting straightforward.
• Wide Temperature Range: −55°C to +105°C operation supports use in both cold-start and elevated-temperature applications.
• Through-Hole Packaging: Radial lead, 2 mm spacing simplifies assembly and rework for prototyping and low-to-medium volume production.
• RoHS Compliant: Meets RoHS directive requirements for environmentally restricted substances.

Why Choose UPJ0J121MDD?
