sunel low frequency transformer series - low frequency transformer manufacturers.sunel the production of low-frequency transformer is used to spread the signal voltage and the signal power, but also to achieve the impedance matching between the circuit, the DC power having a role in isolation. Low frequency transformer is divided into inter-stage coupling transformer input transformer and output transformer unibody inductance the Rao line inductance inductor manufacturers, Shenzhen inductance, electronic news, shape are similar to the power transformer.
