Description
The 74000 & 75000 series are pulse transformers in an encapsulated package with design layouts as through-hole and surface mount types. They can operate over a wide temperature range of -55°C to +130°C. Our proprietary materials and methods allow extreme temperatures of vapor phase, IR or other reflow procedures without degrading the high reliability of their physical form and electrical performance.
