ARCO 40 & 46 
Series Compression
Trimmers

The most popular type of trimmer, especially used in old receivers and transmitters. 
The base is made of the lowest dielectric loss ceramic material and the mica is clear 
India Ruby. The soldering lugs may be bent in any position without affecting capacity 
setting due to the rigid construction of adjusting plates. 
Type 40 Series measures (including lugs) 3/8"W x 9/16"L x 9/16"H.
Type 46 Series measures (including lugs) 5/8"W x 3/4"L x 5/8"H.
