Company Profile

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.

Applications & Operating Conditions

Industry & Application	Typical Operating Conditions	Key Parameters
LED Drivers	Isolated flyback or forward constant current power supply	Turns ratio, power rating, leakage inductance, efficiency, temperature rise
Industrial Controllers	12V, 24V, 48V control systems	Wide input range, isolation, regulation, operating temperature
Power Adapters	2W to 25W depending on topology	Efficiency, standby loss, dielectric strength, dimensions
Smart Home Equipment	Low power flyback applications	Compact size, low no-load loss, stable output
Smart Metering	Project-specific mains input and low voltage outputs	Wide input range, low standby power, isolation

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.
