2432-032-X5U0-402M

Feed through capacitors, commonly known as bypass capacitors, are used in antenna systems, radio frequency (RF) circuits, and communication equipment to reduce noise. The 2432-032-X5U0-402M application field and working principle include its function in a power source filtering circuit and a device used to prevent antenna feedback.

Power Source Filtering Circuit Function

The 2432-032-X5U0-402M feed through capacitor is used to filter high frequency and unwanted electromagnetic interference (EMI) from the power signal. This capacitor acts as a type of filter, and its size determines the type of filter it will be. The standard value of this feed-through capacitor is 400 pF, which is suitable for filtering circuit of noise signal.

In a power source filtering circuit, it works to block high-frequency signals on the line. This can be useful for reducing interference in a radio frequency circuit. The capacitor acts as a short-circuit so that no RF energy can pass through it. It also acts as a low pass filter so that only the frequencies below the cutoff frequency can make it through.

Antenna Feedback Prevention Device

A 2432-032-X5U0-402M feedthrough capacitor is also used to prevent unwanted antenna feedback or reflections. By connecting the capacitor between the transmitter output and the antenna, any high frequency signal that tries to reflect back to the transmitter is blocked, and only the low frequency signal can pass through. This helps limit interference from other radio sources. In addition, it can also prevent the antenna from picking up interference from other signals, such as AM/FM radio or cellular towers.

Working Principle

The 2432-032-X5U0-402M feedthrough capacitor operates on the principle of capacitive coupling. In this type of capacitive coupling, two or more electronic components are connected by a single metallic conductor. The capacitors between the two components will create an electromagnetic field, which will cause a charge to be transferred between the two components. This allows a low-frequency signal to pass through the capacitor while high-frequency signals are blocked.

The 2432-032-X5U0-402M feedthrough capacitor is one of the most commonly used types of capacitors for power source filtering and antenna feedback prevention. Its size and value determine what type of filter it will be, and how effective it is in the application. In addition, its capacitive coupling principle makes it ideal for these types of circuits.
