UPJ1K180MED

The UPJ1K180MED is a radial-lead aluminum electrolytic capacitor designed for general-purpose power applications. It features a low-impedance UPJ series architecture intended for use in switching power supplies and similar power-conversion circuits.

Key electrical characteristics include a rated voltage of 80 V, capacitance of 180 µF with ±20% tolerance, low dissipation factor (tanδ 0.08), a leakage current of 340.2 µA, and a rated life of 2000 hours at 105°C. The part is polarized, RoHS-compliant, and specified for operation from −55°C to +105°C.

Key Features

• Electrical ratings: 180 µF capacitance with ±20% tolerance and an 80 V rated voltage for higher-voltage power rails.
• Low loss performance: Dissipation factor (tanδ) of 0.08, minimizing loss in power applications where efficiency and thermal management matter.
• Controlled leakage: Specified leakage current of 340.2 µA, supporting predictable bias behavior after voltage application.
• Temperature and life: Operates from −55°C to +105°C with a rated life of 2000 hours at 105°C for sustained performance in elevated-temperature environments.
• Package and mounting: Compact radial can, φ6.3 × 11 mm body with 2.5 mm lead spacing for through-hole assembly and dense board layouts.
• Ripple capability: Ripple current specified at 29 mA (120 Hz) and 58 mA (200 kHz) to support AC ripple handling in power circuits.
• Series characteristics: Part of the UPJ low-impedance series, intended and specified for switching power supply use; RoHS-compliant.

Typical Applications

• Switching power supplies: Low-impedance UPJ series design and 80 V rating make this capacitor suitable for energy storage and smoothing in switching regulators and converters.
• General-purpose power filtering: 180 µF capacitance and controlled leakage support bulk decoupling and smoothing on higher-voltage DC rails.
• Space-constrained through-hole designs: Compact φ6.3 × 11 mm can and 2.5 mm lead spacing enable use in dense, radial-lead power boards where board real estate is limited.

Unique Advantages

• High-voltage capability: 80 V rating addresses higher-voltage power rails without series stacking or special accommodations.
• Low dissipation factor: tanδ = 0.08 reduces dielectric losses, helping to control internal heating under bias and ripple conditions.
• Predictable leakage behavior: Specified leakage current (340.2 µA) allows designers to budget bias currents accurately in power designs.
• Robust thermal tolerance: −55°C to +105°C operating range and 2000-hour life at 105°C provide durability for elevated-temperature applications.
• Compact radial package: φ6.3 × 11 mm can with 2.5 mm lead spacing simplifies placement in through-hole assemblies and compact power modules.
• Series-optimized for switching supplies: Part of the UPJ series, which is specified for low impedance and switching-power use, aligning component selection with application needs.
