Information about Telecom Transformers

Telecom transformers are used in applications which require high bandwidths and fast switching speeds. They isolate the signal between primary and secondary grounds. There are many types of telecom transformers. Examples include DSL transformers, xDSL transformers, T1 transformers, E1 transformers, ISDN transformers, LAN transformers, WAN transformers, and ATM transformers. Modem transformers are also available. A DSL transformer or xDSL transformer uses the digital subscriber loop (DSL) or extended digital subscribe loop (xDSL) telecommunication protocols. A T1 transformer or E1 transformer is designed for use with a T1 line or an E1 line, respectively. An ISDN transformer is a telecommunications transformer for integrated services digital network (ISDN), an international standard for the digital transmission of voice and data. A LAN transformer is designed for a local area network (LAN), while a WAN transformer is used with a wide area network (WAN). An ATM transformer works with asynchronous transfer mode (ATM), a packet switching and transmission system also known as cell relay. Like other telecommunications transformers, a modem transformer needs to minimize noise.

Products & Services Related to Telecom Transformers

Audio Transformers

Audio transformers are involved in the transmission of voice or sound signals. They often require wide frequency bandwidth with low distortion and noise suppression.

Current Sense Transformers

Current sense transformers are used to detect and measure current. There are two basic types of products: switch-mode transformers for power conversion applications, and precision-measurement transformers for instrumentation applications.

Gate Drive Transformers

Gate drive transformers are used to drive high-speed switching devices such as field effect transistors (FET) and insulated gate bipolar transistors (IGBT). They are used in applications such as switching power supplies.

RF Transformers

RF transformers transfer energy from one circuit to another by electromagnetic induction. Typically, they are used to increase or decrease voltage as it passes from one side through the other.

Signal Transformers

Signal transformers transfer information from one circuit to another by electromagnetic induction. They are used to increase or decrease the voltage from one side of a power transformer to the other.

Switch Mode Transformers

Switch mode transformers (switching transformers) are used mainly in switching power supplies and DC-DC converters. They provide a storage element for transferring energy from input to output in discrete packets as required in switching power supplies, regulators and converters.
