Common Mode Chokes are components used in electronic circuits for power and signal lines, allowing signals to travel in one direction while impeding or blocking signals in the opposite direction. The SSHB21HS-10145 is a type of Common Mode Choke specifically designed to suppress electromagnetic interference (EMI) and limit conducted electromagnetic radiation.

The SSHB21HS-10145 features a high current capacity and low insertion loss, making it suitable for a variety of applications requiring high levels of signal-to-noise ratio and interference protection. The Common Mode Choke is primarily used in radio communications, such as satellite systems or any system where conducted EMI is a concern.

The SSHB21HS-10145 is an inductor-based device that features two coils which are closely intertwined. The coils are wound in opposite directions and in-phase, creating a planar magnetic field. This magnetic field, in combination with two parallel opposing capacitors, produces a frequency-selective, low-pass filter. The filter attenuates high frequency conducted interference, while allowing a true signal path-conducted in the same direction as the filter-to pass through.

The two separate, but related attenuation curves, also allow the SSHB21HS-10145 to be used in noise immunity applications. In noise immunity applications, the choke allows a true signal to pass through, while significantly suppressing high frequency, harmonically related noise.

Some of the additional features of the SSHB21HS-10145 include a wide operating temperature range (-55 °C to +125 °C), a maximum DC current rating of 1.6A, and an insertion loss of up to 0.15 dB. It is rated for a maximum input power of 1.05 W and is offered in a compact surface mount package measuring 4.0 x 3.2 mm.

The SSHB21HS-10145 is a critical component in many high-reliability electronic systems, ensuring reliable signal transmission and immunity to the detrimental effects of conducted EMI. This Common Mode Choke is an ideal solution for anyone looking for a reliable, high performance filter for their power or signal lines.
