EE16 is E‑shaped. Its vertical or horizontal bobbin design facilitates easy mounting on PCBs. Compared with toroidal inductors, it can not only perform filtering but also provide voltage transformation and electrical isolation functions. Products that have passed safety certifications can ensure the creepage distance meets safety requirements.

Core advantages of EE transformer
1. Compact footprint, save valuable PCB space with small‑size EE16 ferrite core and vertical DIP package.
2. Stable performance for low‑power flyback SMPS within several watts to 20W, low core loss at 60‑150kHz operating frequency.
3. Sufficient creepage distance on bobbin. Compatible with triple‑insulated wire to meet safety isolation requirements for adapters and chargers.
4. Mature standard core, stable supply chain and standardized winding process, cost‑effective for mass production.
5. Flexible customization: turns ratio, pin assignment and insulation level supported, evaluation samples available for IoT, charger and small appliance projects.

FAQ
Q: What is the typical operating frequency of EE16?
A: Typical operating frequency 60‑150kHz, adjustable according to core material and winding design.
A: Typical operating frequency 60‑150kHz, adjustable according to core material and winding design.
Q: Can EE16 meet safety isolation requirements?
A: Yes. The bobbin has reserved creepage distance. By adopting triple‑insulated wire and insulating tape, safety isolation can be achieved for chargers and adapters.
Q: What is the difference between EE16 and EE13 transformer?
A: EE16 has larger core size, higher power capacity and better heat dissipation than EE13. EE13 is more compact but only for power below 5W.
Q: What package form is EE16?
A: Standard vertical DIP through‑hole package, compatible with automatic PCB insertion for mass‑volume production.
Q: What applications is EE16 transformer suitable for?
A: EE16 is low‑power high‑frequency transformer for several watts to 20W flyback power supplies. Widely used in chargers, adapters, IoT devices and small‑appliance control boards.
