Low Loss Compact EE19 High Frequency Transformer Stable Durable For LED Drivers

Low Loss Compact EE19 High Frequency Transformer
Stable and durable transformer designed for LED drivers and other space-constrained electronic equipment.
Product Overview
The EE19 is a compact ferrite core high frequency transformer platform designed for isolated power conversion in LED drivers, adapters, auxiliary power supplies, industrial controllers, smart meters, and other space-constrained electronic equipment.
The transformer features an EE ferrite core, insulated bobbin, multiple through-hole pins, and tape-insulated winding assembly. Final performance depends on converter topology, input voltage, output requirements, switching frequency, and other operating conditions.

Frequently Asked Questions
What information is required to customize an EE19 transformer?
Please provide converter topology, input voltage range, output voltage and current, continuous and peak power, switching frequency, duty cycle, target inductance, leakage limit, isolation requirement, dimensions, PCB pinout, temperature conditions, and annual demand.
What power can an EE19 transformer handle?
Approximately 2W to 25W is a broad reference range. Actual capacity depends on topology, frequency, winding design, cooling, and allowable temperature rise.
Can multiple secondary outputs be provided?
Yes. Multiple isolated or connected secondary windings can be developed when winding space, insulation, power distribution, and temperature rise permit.
