SFJEL5000103MX1

Feed Through Capacitors

SFJEL5000103MX1 is a particular type of feed through capacitors used as a low-frequency AC filter in a wide range of applications, such as motor control systems, medical equipment, and in other switch-mode power supplies. It has excellent properties such as low impedance and a strong insulation against high-voltage transients, allowing it to be used in harsh-environment, industrial and military applications.

Application Field

For example, the SFJEL5000103MX1 is well-suited for use in high-current off-grid applications. Examples of these are motors used in agricultural and industrial applications, such as pumps, fans, and the like, as well as in the automotive and aerospace industries. In these instances, the SFJEL5000103MX1\'s low impedance and strong insulation against voltage transients make it ideal for use in power supply configurations where the load requires constant and stable power.

The SFJEL5000103MX1 is also well-suited for use in medical devices, such as pacemakers and other implantable medical devices, where its low impedance and excellent insulation enable it to filter out interference while providing consistent power to the device.

The SFJEL5000103MX1 is also used in a wide variety of other applications, such as power converters, audio systems, and even in some audio amplifiers. In these cases, its low impedance and strong insulation against voltage transients is an essential asset.

Working Principle

The SFJEL5000103MX1 is a feed through capacitor, synonymous with “transmission line capacitor”. This technology functions by using an insulated dielectric separator, which allows for isolation between the voltages of the two terminals. This insulated separator is composed of compressed capacitor foil, which is then wrapped in an input and output terminal in order to deliver a transmission line. The dielectric separator helps to reduce line noise, which is often referred to as “pick-up”.

The input and output terminals are connected to a varying or alternating current by using a lead. The capacitor foil works in tandem with the lead, allowing for the charge to be transmitted to the output terminal. This creates the effect of the capacitor, which is responsible for the filtering of noise and the stabilization of voltage.

While the SFJEL5000103MX1 can be used in a variety of applications, it is particularly effective in high-current, off-grid applications, as well as in medical devices. Its low impedance and strong insulation against voltage transients makes it an ideal choice for many applications that require consistent and stable power.
