  • I am writing to you today to thank you and your team. We had an internal issue where we triggered two pull orders for V4L1008 for immediate delivery. Your lead time is 2 weeks. Initially Patti heard back that Dielectric did not have stock and we would have to wait the full lead time. Thanks to the responsiveness of Dielectric, raw material was found and parts fabricated in a day. This kept our lines up and our customers happy. … We recognize and appreciate this extra effort.
