C&D pulse transformer exhibit 1kVrms isolation
C&D Technologies (NCL) Ltd's 786 series of miniature pulse transformers offers inductance values up to 10mH and isolation ratings of 1kVrms.
The series features five different winding configurations and are available in surface-mount and through-hole versions. They are suitable for line-coupling, matching, and isolation applications, as well as in small, isolated power supplies and as common-mode chokes in filtering applications.
The transformers offer primary inductance values between 100µH and 10mH and employ toroidal construction. Winding configurations options are 1:1, 1:1:1, 2:1, 1CT:1 and 1CT:1CT, while dc resistance values range from 17 milliohms to 1.34 ohms.
Sully encapsulated using UL 94V-0 materials, the transformers have dimensions of 9.52-by-8.89-by-6.35mm (DIP) and 12.7-by-8.89-by-6.35mm (SMT). They are specified for operation over the 0°C to 70°C temperature range.
