Product Specification

PQ3225 Horizontal Straight Plug High Frequency Transformer High Voltage Pins 6+6

1.Product Description

PQ3225 direct insertion high-frequency transformer is a high-performance electronic component. It has a compact structure and vertical axis, designed to operate in the frequency range of 20kHz-500kHz. It can handle an output power of 10W to 1000W and operate stably within a temperature range of -40 ° C to+180 ° C. Low loss, low temperature rise, and excellent anti-interference performance. This transformer is easy to wrap around due to its circular center pillar. It is widely used in various fields such as switching power supplies, electric vehicle chargers, DC-DC converters, and communication power supplies.

2.Features

The PQ3225 direct insertion high-frequency transformer mainly consists of the following structural components:
1. Core: Generally, ferrite cores designed to meet the requirements of new switching power supplies are used. The shape is usually PQ type, which can meet the requirements of reducing copper and iron losses at high frequencies and meet the temperature rise needs of switching power supplies.

2. Winding
--Primary winding: It is a winding that inputs electrical energy and generates a magnetic field through alternating current.

--Secondary winding: Coupled with the primary winding, it generates induced electromotive force under the action of a magnetic field and outputs electrical energy. Usually, the primary and secondary windings are wound on different winding columns of the iron core. For example, PQ3225 may have primary winding columns and secondary winding columns, with winding slots on the winding columns for easy winding of the coil.

--Winding form: Generally in the form of three windings, in addition to the primary winding and secondary winding, there may also be auxiliary windings, etc., used to achieve some special functions, such as providing feedback signals, supplying power to other circuits, etc.

3. Skeleton: provides support and fixation for the winding, usually in a vertical structure. Having specific dimensions and shapes to accommodate the installation of iron cores and windings. There are lead terminals on the skeleton for easy connection to external circuits, making product installation more reliable.

4. Pin: A metal pin that connects the lead wires of the winding to the external circuit, usually multiple in number, used to achieve electrical connection between the transformer and other circuit components, transmitting the electrical energy of the primary and secondary windings to the corresponding circuit.

5. Insulation layer
--Winding insulation: Insulation materials such as insulation tape or insulation paint are usually wrapped around the coils of the winding to avoid short circuits between the coils and ensure that the current flows along the designed path. For example, a coil is wound on the outer wall of the winding groove, and a second insulation tape may be placed on the outer wall of the coil far away from the winding groove.

--Insulation between iron core and winding: There will also be insulation materials between the iron core and winding to prevent electrical short circuits between them, which will affect the normal operation of the transformer.

--Overall insulation: Some may also install insulation shells or coatings on the outside of the entire transformer to provide protection and insulation, improving safety during use.
