For sale here we have the above…

Used for the construction of inductors and transformers.

Ferrite diameter is 4.9mm 
Outer diameter of case is 28mm. 

Overall length is 30mm.  

The unit is supplied without windings as these are added by the customer to meet their own requirements (DIY inductor transformer)

These units were made by Mullard in the late 50s. 

This LA2702 unit contains a 1230 ferrite core. 

The LA2702 was the ID given to the complete assembly.

To dismantle the case there is a locking nut which has to be loosened enabling the top cap to be rotated slightly. 

The top may then be removed and the core accessed. 

Also included is the trimming core which was used for fine tuning the inductors.

A recent customer supplied us with the following feedback…

“I worked with this series in the 60’s and they were going obsolete then. The LA2702 is a 14mm core with the equivalent being a pair of LA1230 cores plus adjuster and possibly a base.

Best bet is to wind 100T and measure the inductance. If you double the turns the inductance goes up 4 times. I’m not sure if this was a gapped core, if not it will saturate easily if you put DC through it. From memory they were only intended for AC applications, but quite high inductance values could be obtained.”

PLEASE NOTE!

These parts came to us as part of a lot of surplus stock from a large Milspec type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however pristine, stored with us still in their original packaging and ‘as new’ in all respects, the photographs are representative of their excellent condition, and, as with all our products they come with a full guarantee. 

If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
