Product Description
Custom ETD49 High Voltage 12V High Frequency Transformer for Inverter
The ETD49 high frequency transformer (Model: ETD49-402-13524) is a vertical through-hole switching power transformer built on a high-permeability ETD49 ferrite core (PC40 / DMR40 grade). Designed for 12V DC input high-voltage output inverter circuits, it delivers stable power conversion at switching frequencies from 20 kHz to 100 kHz, with low core loss, low temperature rise and excellent EMI performance.
As a professional magnetic components manufacturer, we supply this ETD49 transformer as a fully customized (OEM / ODM) part — turns ratio, inductance, pin-out, bobbin, wire type and safety spacing are all engineered to your schematic and application.
Key Features
- ETD49 ferrite core — large window area and low loss material for high power density in a compact footprint
- Wide input / output design — standard 12V DC input, high-voltage output; other combinations built to drawing
- High efficiency — optimized sandwich winding reduces leakage inductance and copper loss
- Low temperature rise — continuous operation from -40 °C to +125 °C, suitable for outdoor and industrial environments
- Reliable insulation — Class B / F / H systems, margin-wound or TIW (triple insulated wire) reinforced isolation
- 100% tested — turns ratio, inductance, DCR, hi-pot and leakage inductance checked before shipment
- RoHS & REACH compliant materials; UL-recognized bobbin, tape and enameled wire available on request

FAQ
Q1: Are you a manufacturer or a trading company?
We are a manufacturer with our own winding, assembly and testing lines, offering full OEM / ODM service.
Q2: Can you make transformers to my drawing?
Yes. Send your drawing or specification and we will confirm feasibility, propose a design and quote within 24 hours.
Q3: What is your MOQ?
Sample orders are accepted for evaluation; MOQ is flexible for customized models.
Q4: How long is the lead time?
Samples in 7-10 working days; mass production 15-25 days after order confirmation.
Q5: How do you pack and ship?
Anti-static bag + inner carton + export carton on pallet. Shipping by DHL / FedEx / UPS, air or sea freight; EXW, FOB and CIF terms available.
Q6: Do you support 12V input with other output voltages?
Yes. The 12V input is only the standard configuration — output voltage, power and frequency can all be redesigned to your requirement.
