A signal transformer is used in electronic devices as a step-up/step-down, impedance matching, or isolating component. Increased advancement in technology pertaining to electronics drives growth of the signal transformer market. Power transformers that carry high current are not suitable for use as signal transformers. A transformer is an electrical device comprising two coils mounted on a core, namely primary and secondary.
The basic principle of working is that when the primary winding is connected to a current supplying source and a signal passes into it, an electromagnetic force (EMF) is produced. This electromagnetic force induces a voltage in the secondary coil, which is based on the number of windings per coil and the number of turns.
In a ‘step-up’ transformer, if the number of windings are more on the secondary coil, the induced voltage is high as compared to the applied voltage. Likewise, in a step-down transformer, the number of windings are more on the primary coil, and the induced voltage will be less than the applied one.
Signal transformers find applications in electronic devices, especially those pertaining to telecommunication, radio frequency, audio, video, and other general purposes. Signal transformers are used when the signal from one circuit is transferred to another circuit and it needs to be coupled, or stepped up or down or amplified, depending on the requirement.
Signal transformers are also used for phase shifting from stage to stage in an electronic device. Signal transformer products have provided unparalleled innovative application-specific solutions to the electronics industry for more than 50 years.
On the basis of the type of signal used in signal transformers, they are classified into digital, audio, electronic, RF, telecom/LAN. Digital transformers carry signals comprising discrete values, as opposed to analog signals. Whereas, audio transformers are used for voice and data transmission with receivers, amplifiers, speakers and audio cables.
The operational frequency range for these transformers typically ranges from 300 Hz to 20 kHz. Electronic transformers are voltage or current transformers used to test electronic devices.
North America is forecasted to hold a relatively large market share among all regions in the coming future. This can be attributed to evolution in the electronics industry in the region, along with high imports and exports. Europe holds the second spot in terms of market share, followed by the APAC region.
Growth in the APAC region is spearheaded by China, owing to innovation in the field of electronic devices and the presence of manufacturing companies in the region.
Advancements in the telecommunication industry, rapid rise in technology, and the increased rate of usage of audio and video devices are factors that drive the signal transformation market. Signal transformation is frequently used in audio applications to match impedance or isolate signals. Adopting new technologies in RF radio frequency applications drives market growth for signal transformers. The evolving electronics industry utilizes signal transformers as a means of protecting electronic devices, which in turn drives growth of the market.
