Power line filter modules are electrically shielded electronic components, typically consisting of three galvanic isolated windings on amorphous alloy cores. They are used for RF interference suppression, transformers, and chokes. 100TYSS104 is a two-stage common-mode noise filter designed for the protection of sensitive electronic equipment against the high frequency electromagnetic interference (EMI) generated in automotive and railway applications. To understand more about its application field and working principle, let’s take a closer look.

Application Field

The 100TYSS104 filters are designed for use in automotive can bus applications, such as electric power steering, engine control, and airbag sensory systems. It is also used in railway signaling and interlocking systems. It can be applied in the range of 6 kHz to 1 GHz, so applications like locking and unlocking doors, as well as other scenarios with high frequency requirements, would be a great fit. As a two-stage filter, it provides superior filtering performance and a significant improvement to common-mode noise, achieving an attenuation of up to 25dB over a bandwidth of up to 6kHz-1GHz. It also has an up to 25dB return loss across the same bandwidth.

Working Principle

The 100TYSS104 filter works by combining three galvanically isolated windings on an amorphous alloy core. The windings act as tunable inductors, with each winding providing a different level of inductance. This allows for a wide range of frequency responses, which can be tuned to match the application\'s specific requirements. By combining these windings in a two-stage configuration, the filter is able to provide an improved common-mode noise suppression than traditional single-stage filter designs. As an added benefit, the two-stage configuration makes the filter highly stable with minimal drift in the frequency response over time.

In summary, the 100TYSS104 is a two-stage common-mode noise filter for the protection of sensitive electronic equipment against the high frequency electromagnetic interference (EMI) generated in automotive and railway applications. It is designed to work in the range of 6kHz-1GHz with an attenuation of up to 25dB and a return loss of up to 25dB. It achieves this performance by combining three galvanically isolated windings on an amorphous alloy core, providing tunable inductance which can be tuned to match the application\'s frequency requirements. Its two-stage configuration makes the filter highly stable with minimal drift in the frequency response over time.
