P1165 – TBC

The P1165, identified as a transformer, likely manufactured by ETAL based on co-location of the designation, is characterized as a wound magnetic component. Without further manufacturer specifications, definitive electrical parameters remain unspecified; however, inferences can be made. Given ETAL’s specialization in magnetics, the P1165 likely operates within the frequency range of tens of kHz to several MHz, dependent on core material (potentially ferrite or powdered iron). Key design considerations would include primary and secondary inductance (Lp, Ls), leakage inductance (Lk), turns ratio (n), DC resistance (DCR) of both windings, and saturation current (Isat). The ETAL designation suggests a focus on minimizing core losses and optimizing efficiency for switch-mode power supply (SMPS) applications, potentially in buck, boost, or flyback converter topologies. Thermal performance, influenced by core size and winding construction, is a critical parameter requiring empirical validation in intended operating conditions.
