Designed for compact switch-mode power solutions, the STEEC6.2 Series utilizes EEC6.2 ferrite cores with UL-certified phenolic bobbins. Precision wound with 180℃ polyurethane-enameled wire, it delivers ±15% inductance stability and reinforced isolation (0.5kV AC). Featuring #1218 high-temp tape and varnish encapsulation, it operates reliably at 130℃ ambient temperatures. Ideal for space-constrained industrial and consumer applications.
