The EE19H Series High-Frequency Transformer is an essential component designed for modern, high-density power electronic systems where space is a critical constraint. Featuring a standardized "EE" core geometry with horizontal orientation, this transformer lies flat against the PCB, making it ideal for ultra-slim adapters, LED drivers, and low-profile electronic modules.
Optimized for switching power supply applications from 5W to 18W, the EE19H series provides the perfect balance between physical compactness and robust power-handling capability. With precision-molded bobbin and 5+5 pin configuration, it operates reliably in the 65kHz to 500kHz range while meeting strict international safety standards.

The Mn-Zn Ferrite Core selection ensures high saturation flux density even at 100°C operating temperatures. Our proprietary winding patterns minimize leakage inductance to less than 1.5%, protecting switching MOSFETs from high-voltage transients and enabling smaller, lower-cost snubber circuits.
With dielectric strength of 2500V-3500V, this transformer is suitable for isolation applications in both consumer chargers and rugged industrial environments. Every unit undergoes verification using advanced Automatic Test Equipment to ensure consistent parameters across all production batches.
Core Geometry Advantage: Optimized rectangular winding windows allow dense copper wire packing, maximizing current-handling capability in minimal space. Precision-gapped center legs prevent saturation during transient load spikes.
Precision Winding Technology: High-precision CNC multi-axis machines ensure consistent tension and placement of every turn, eliminating internal short circuits and minimizing parasitic capacitance for stable operation above 100kHz.
Triple-Insulated Wire Capability: Provides reinforced insulation within the winding window, doubling safety margins without consuming additional space.
Resin Impregnation Process: Vacuum varnishing creates moisture-proof, vibration-resistant units that eliminate audible "whining" from magnetostriction, making them ideal for noise-sensitive environments.
Automated Quality Verification: High-resolution optical inspection and full electrical testing of every unit reduces total cost of ownership by eliminating inspection failures and field returns.
Consumer Electronics & Smart Home: Ultra-slim AC adapters, IoT hubs, and smart lighting controllers where horizontal profile enables thinner product designs.
Industrial Control & Precision Instrumentation: PLC modules, industrial sensors, and process monitoring tools requiring reliable performance in electrically noisy environments with wide temperature fluctuations.
LED Lighting & Display Technology: High-efficiency, flicker-free drivers for LED arrays with low electromagnetic footprint that preserves wireless dimming protocols.
Telecommunications & Mobile Charging: Compact power modules for 5G infrastructure, mobile chargers, and networking equipment supporting fast-charging protocols.
