Key Features

• Electrical Rating — 330 µF nominal capacitance, rated voltage 50 V, with capacitance tolerance ±20% measured at 120 Hz, 20 °C.
• Low Impedance Design — UPJ series specification indicates low impedance characteristics suitable for switching power supply applications.
• Thermal and Endurance Performance — Operating temperature range −55 °C to 105 °C and rated endurance of 2000 hours at 105 °C.
• Loss and Leakage — Tangent of loss angle (tan δ) specified at 0.10 for 50 V parts; leakage current specified as 495 µA.
• Ripple Current Capability — Ripple current ratings of 67.5 mA at 120 Hz and 135 mA at 200 kHz for handling AC ripple on DC rails.
• Compact Radial Package — Radial can package, dimensions φ6.3×11 mm, lead spacing 2.5 mm with ±0.5 mm tolerance; supplied in bulk (no terminal forming) or bag packing.
• RoHS Compliant — Meets RoHS requirements as listed in the product data.

Typical Applications

• Switching Power Supplies — Low-impedance UPJ construction and 50 V rating make it suitable for bulk smoothing and output filtering in switch-mode power circuits.
• General-Purpose Electronic Equipment — Specified for general-purpose applications where radial-lead electrolytics are required for board-level power support.
• Radial-Lead Power Circuits — Compact φ6.3×11 mm radial can and 2.5 mm lead spacing simplify placement in tight PCB layouts for power rail decoupling and energy storage.

Unique Advantages

• Designed for Switching Environments — The UPJ series’ low-impedance profile targets switching power supply demands, improving ripple handling compared to standard electrolytics.
• High-Temperature Endurance — 2000 hours at 105 °C provides predictable lifetime performance for sustained elevated-temperature operation.
• Measurable Loss and Leakage Specs — Specified tan δ (0.10) and leakage current (495 µA) allow designers to size and predict losses and standby currents accurately.
• Space-Efficient Form Factor — φ6.3×11 mm radial can offers a compact solution for board-level power designs where axial clearance or component density is a concern.
• RoHS Compliance — Enables use in designs requiring RoHS-conformant components.
