Metalized Polycarbonate Axial Capacitors are often highly regarded for their unique ability to withstand temperatures of -55°C - +125°C without a negligible change in voltage De-rating*. Meanwhile most axial film capacitors usually have a voltage de-rating at temperatures above 85°C. Most capacitors that don’t de-rate at higher temperatures happen to be larger in physical size. These capacitors have a low dissipation factor, which is usually less than 0.36%.
* De-rating – Occurs when you run a capacitor at lower values to prolong its life and stability. This usually occurs at higher temperatures of 85°C and above.
Metalized polycarbonate axial capacitors are often referred to as “Yellow Jacket Capacitors” because of their bright yellow case color.
Metalized Polycarbonate Capacitors can be found in aerospace equipment, navigation equipment, and precision equipment.
