An informative white paper from Datatronics Romoland, Inc., provides a discussion of the design, development and delivery of affordable magnetic components. The design development process begins once performance requirements are specified. Upon design approval, the procurement of materials for a prototype build is initiated. During this stage, specifications are not final and options remain open for cost-effective production. Specifications must be reviewed and design trade-offs evaluated to ensure that the technical requirements are economically attainable with consideration given to performance and tolerance in relation to affordable cost.

Initially the electrical specifications are tentative as there may be ambiguity about what are the minimum allowable performance requirements. One approach in the development of an electrical specification is to specify performance parameters. Limits are given for parameters such as input/output voltages, currents, frequency and leakage inductance, etc. Another approach is to provide information about the circuit in which the device will function. The functional approach can more appropriately optimize the design by understanding its performance requirement within the circuit.
