Common Mode Chokes are used in a variety of electrical and electronic applications to provide a stable power supply by reducing external interference, such as noise, and to improve the signal to noise ratio. One such application is CAF-1.5-3.3.

CAF-1.5-3.3 is a three-phase common mode choke used in low-power applications from 20 kHz to 1MHz and includes support for three inductors, one each for AC, DC, and ground components. It delivers a maximum power attenuation of 40dB with low insertion loss and a flat frequency response between 20kHz and 1MHz. It is constructed with a ferrite core and composite ferrite powder for space-saving and low-cost applications.

The principle of operation behind CAF-1.5-3.3 is based on creating an electrical barrier between the output and input side of an electrical system. In other words, it acts as a filter for any external EMI noise, providing low-noise power. It also helps to prevent electromagnetic energy from escaping the system, thereby maintaining a clean environment. CAF-1.5-3.3 is suitable for a variety of applications such as RF power supplies, DC/DC converters, power amplifiers, power inverters, and avionics.

CAF-1.5-3.3 provides three isolated inductors for filtering out common-mode noise. The windings are connected in series between the input and output, forming a differential-mode filter. The inductors in series create an inductive reactance, forming a low frequency cutoff. The choke works to reduce the common-mode noise, while still allowing the desired signal to pass.

The CAF-1.5-3.3 common mode choke also features a temperature-compensated design. It is designed to compensate for changes in temperature ensuring stable performance over a wide range. The choke is also designed to provide a high degree of shielding, making it suitable for use in harsh environments.

The CAF-1.5-3.3 common mode choke is a crucial part of many applications due to its ability to efficiently reduce unwanted electromagnetic interference. It is useful in applications involving emission reduction, noise reduction, harmonic suppression, and in devices requiring low-noise operation. It offers excellent performance, low cost, and small size, making it a great choice for a wide range of applications.
