High frequency matching transformers fall under input, interstage and output transformers. Input transformers are connected at the amplifier input and match the signal source's output resistance with the amplifier's input resistance. As the input signal level is relatively low, such transformers require good protection from external magnetic fields.
Matching transformer from Hefei Mycoil is intended for telecommunications equipment. It is equivalent to SM-LP-5001. Asymmetric transformer i.e. it has two identical windings. With planar leads intended for SMD printed wiring. However, they also allow soldering into holes. It has the transformation ratio of 1:1; its input and output impedance is 600 Ohm. The transformer's insulation resistance is 100 mega Ohm. It is a small device with the dimensions being 12.5× 9.6 ×7.36 mm.
We produce various audio transformer and impedance matching transformers. All matching transformer materials we used are environmental protected. We accept custom made and OEM service.
