UPZ2E121MND9

The UPZ2E121MND9 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPZ series. It is a radial-lead, polarized capacitor specified for 120 µF at a 250 V rated voltage, designed for general-purpose applications that require compact high-voltage capacitance.

Key value comes from its combination of miniature φ10 × 50 mm packaging, a wide operating temperature range of −40°C to 105°C, and defined endurance characteristics (2,000 hours at 105°C), making it suitable where compact high-voltage filtering and energy storage are required within the stated specifications.

Key Features

• Electrical Characteristics – Rated capacitance 120 µF with tolerance −20% to +20% (measured at 120 Hz, 20°C) and a rated voltage of 250 V.
• Dissipation Factor (tan δ) – tanδ = 0.15 specified at 20°C, 120 Hz and 250 V, providing a defined loss characteristic for design margin calculations.
• Leakage Current – Specified leakage current of 1300 µA (measured after 1 minute at 20°C under rated voltage), enabling predictable bias current in circuits.
• Ripple Current Capability – Rated low-frequency ripple current of 740 mA at 120 Hz and high-frequency ripple current of 1.036 A at 10 kHz, for handling AC ripple within the specified frequency bands.
• High-Temperature Endurance – Endurance rating of 2000 hours at 105°C under DC bias plus rated ripple, with post-test limits on capacitance change, tan δ, and leakage current as specified.
• Mechanical & Packaging – Compact radial CAN package, size φ10 × 50 mm, lead spacing 5.0 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Operating Temperature – Specified operating range from −40°C to +105°C for use across a wide ambient span.

Typical Applications

• General-Purpose Power Circuits – Suitable for compact power supply stages and circuits requiring 250 V rated capacitance where miniature high-voltage components are needed.
• Industrial Electronics – Fits equipment that requires defined high-temperature endurance (2,000 h at 105°C) and clear ripple-current handling in both low- and high-frequency conditions.
• Compact High-Voltage Modules – Useful where a small footprint (φ10 × 50 mm) and radial-lead mounting are preferred for assembly in tight layouts.

Unique Advantages

• Compact high-voltage footprint: φ10 × 50 mm construction provides 120 µF capacitance at a 250 V rating, enabling smaller designs without sacrificing voltage capability.
• Defined ripple performance: Published ripple current ratings for 120 Hz (740 mA) and 10 kHz (1.036 A) allow designers to size capacitors against measured ripple at specific frequencies.
• Predictable leakage behavior: Specified leakage current (1300 µA) and datasheet leakage formula help in budgeting DC bias current in the design.
• High-temperature endurance: 2000-hour rating at 105°C under DC bias plus rated ripple, providing a measurable reliability baseline for thermal-stressed designs.
• Radial-lead ease of assembly: Standard lead spacing (5.0 mm ±0.5 mm) and radial can package simplify through-hole mounting and prototyping workflows.
• Wide operating range: −40°C to +105°C rating supports use across a broad set of ambient conditions within the specified limits.
