This page explains how High-Frequency Transformer is classified within Electrical Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A transformer designed to operate at high frequencies, typically above 20 kHz, used for efficient power conversion and isolation in electronic circuits.
Technical details and manufacturing context for High-Frequency Transformer
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Rated Power | 50–500 W | Power rating determines size and core selection. |
| Operating Frequency | 20–500 kHz | Higher frequency allows smaller core and fewer turns. |
| Primary Inductance | 0.1–10 mH | Affects magnetizing current and efficiency. |
| Leakage Inductance | 0.5–5 µH | Low leakage is critical for high efficiency. |
| Isolation Voltage | 3–5 kV | Ensures safety isolation between primary and secondary.IEC 61558 |
| Efficiency | 95–99 % | Higher efficiency reduces heat and energy loss. |
| Operating Temperature | -40–125 °C | Exceeding limits may degrade insulation and core. |
| Insulation Class | B–H | Higher class allows higher operating temperature.IEC 60085 |
| Core Material | PC40–PC95 | Material grade affects losses and saturation. |
| Wire Material | CU–ALU | Copper offers lower resistance; aluminum is lighter. |
| Weight | 10–500 g | Affects mounting and space constraints. |
| Dimensions (L×W×H) | 10×10×5–50×50×30 mm | Must fit PCB layout and enclosure. |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.
Quoted from the published standard.
6 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The typical operating frequency range is 20 to 500 kHz, as listed in the directory. However, the exact frequency capability depends on the specific model and core material. Always verify with the manufacturer.
The isolation voltage is listed as 3 to 5 kV, with IEC 61558 as a reference standard. This indicates the transformer's ability to provide galvanic isolation, but actual ratings must be confirmed for the specific part.
Ferrite cores are used, with material grades ranging from PC40 to PC95. The grade affects losses and saturation characteristics. Selection depends on the operating frequency and power level.
Consider the required power rating, operating frequency, primary and leakage inductance, isolation voltage, efficiency, and thermal environment. Verify all parameters with the supplier to ensure compatibility with your circuit design.
