Power Line Filter Modules

The B84110A0000A010 is a power line filter module from EPCOS. This filter is generally used in applications with operating voltages of 19 to 20 V and a rated current of 10 A. Its purpose is to provide effective electrical interference suppression and overall signal integrity to a system. This filter is constructed with thermally protected bobbins with surface mount technology, enabling it to work in more compact designs and optimize performance in a range of applications.

The housing of the filter is designed to dissipate thermal losses and ensure that the component can operate in harsh environments. This filter has integrated two bidirectional suppression capacitors in a single-stage configuration. It is also built with an integrated common-mode choke and a differential-mode choke, providing high levels of protection against transient currents and voltage surges.

In terms of its working principle, the filter works by blocking the induction of power-line noise or interference. It is typically connected in series with the power line and as such it creates an electromagnetic field which acts as a shield. This is achieved by the filter\'s construction with two bidirectional suppression capacitors, an integrated common-mode choke and a differential-mode choke. This configuration provides high levels of protection against transient currents and voltage surges.

The filter is also designed to provide an effective low-impedance path to ground for common-mode and differential-mode noise. This facilitates the efficient discharging of the possibly interfering transients from the power lines to the ground. This reduces the differences between the ground potential and the power-line voltage, thus reducing the likelihood of any interference being passed along the power line into the system.

Its wide operating temperature range of -40°C to +125°C ensures reliable operation in extreme environmental conditions. The filter can also withstand the hight noise immunity and high surge levels demanded by current power supply system applications. This makes the filter ideal for use in industrial applications, automotive applications, and consumer applications.

In summary, the B84110A0000A010 power line filter module provides cost-effective protection from power-line noise and interference, enabling high-performance operation in a wide range of applications. Its construction with integrated bidirectional suppression capacitors, an integrated common-mode choke, and a differential-mode choke makes it an ideal choice for applications requiring protection from transient currents and voltage surges.
