LL1636 Lundahl microphone trasformer -2dBU applicazioni speciali - nucleo amorfo

LL1636 is an audio input transformer for applications where a high turn’s ratio is desired. The transformer is built up from two coils, each with a secondary winding surrounded by shields and two primary windings. This structure results in an excellent frequency response. All winding ends are available on the pins. Thus, the transformer can be configured for a number of different turn’s ratios. The LL1636 is made with amorphous core material. As this type of core does not store energy (unlike conventional mu-metal cores) the low frequency resonance with external series capacitors is practically eliminated.
