Founded in 1979, Thinking began production of NTC Thermistors in 1989, rapidly establishing 2 Chinese factories. In 1997 they developed their first Varistors and PTC Thermistors. 2000 to 2008 saw the company go ‘public’ and also develop 4 more factories, which included TS (AECQ) qualification and the securing of all relevant CL/UL/VDE and TUV qualifications.
The launch of the TVS diode range in 2016 has effectively completed a product portfolio which now addresses all aspects of Protection, whether Over Voltage, Over Current or Over Temperature.
Clients and Thinking approvals are across all market sectors, including the likes of Bosch, Panasonic, Schneider, Foxconn and Hella. Whilst the applications are extensive, ranging from Automotive, Metering, Safety and Security and obviously Power Supply.
DMTL initially operated via another UK Distributor, rapidly gaining success in Designing in the UK, particularly in the fields of Smart Metering and PSU. This led to DMTL’s direct appointment as Thinking’s Distributors in 2011.
Since then, ably supported by the technical and manufacturing teams at Thinking, DMTL have successfully developed applications and supply in sectors including, Lighting Control, Fire and Safety, PSU, Telecoms, Metering and a range of PDA uses.
