Engineering 20.03

Normal operation is continuing at Charcroft, with Product Specialists and Sales staff working from home and shipments being made from our fully UK-based inventory.

We are in daily contact with suppliers and customers to monitor the industry response to the changing situation. The information gained from this will support the efficient planning which is essential to ensure the highest possible service.

This Engineering Intelligence also introduces new passives which are designed to operate in harsh environments. There is also a new voltage-controlled crystal oscillator and DC-DC converter for delivering robust reliability, and a series of customisable electrical pyrotechnic igniters.

Contact me if you have any questions, or use the links against the products below to request a sample.
