DMTL are fully franchised, authorised Voltronics distributors.

Voltronics has been acquired by Knowles Capacitors and is a premier global source for application specific multilayer ceramic capacitors and EMI suppression filters.

As a result of DMTL’s longstanding relationship and success with Knowles ( SYFER), DMTL have been awarded the Voltronics Franchise. This affords DMTL the ability to strengthen our product offering with Precision Trimmer Capacitors provided by the world’s leader in the design and manufacture of these products. Voltronics trimmers include air, glass, sapphire, and PTFE dielectrics that can be used from 1 MHz to over 2 GHz and at voltages up to 20,000 VDC.

Affording access to the MRI and NMR industries, Voltronics has an extensive line up of Non-Magnetic components. These include trimmer capacitors, chip capacitors, coils, baluns, diodes and connectors. 

Voltronics consider their strengths to be having  the widest range of Trimmer capacitors on the market, high voltage & high power. Glass, Sapphire, PTFE, Quartz and Air and Ceramic dielectrics and their cost competetive NM MLCC solutions with short lead times.
