WebMALVERN, Pa. — September 26, 2024 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new resonant transformer for inductor-inductor-capacitor (LLC) applications that features both the transformer and an integrated inductor in a single package. Designed to save PCB space while simplifying layouts and reducing component mounting … WebThere is an industry rule of thumb that I often see quoted: “The leakage inductance should be 1% of magnetizing inductance for a transformer.” In our design example, the leakage is less than 0.2% of magnetizing inductance at 10 kHz, and 0.1% at 10 MHz. Never accept the 1% figure from a manufacturer as a design objective.
