PQ4045 High Frequency Transformer
Custom PQ4045 High Frequency Transformer for Industrial Power Conversion
A customizable PQ-core switching power transformer for high-frequency power electronics, designed for power supply manufacturers and industrial electronics developers.
Product Introduction
The PQ4045 high frequency transformer is a custom magnetic component for industrial power conversion. It uses a PQ core structure with a tape-wrapped winding, a tape band around the core, black fixing material at the base and a mounting base plate. The product label shows the PQ4045 model, the CHIPSEN brand, a MTPQ4045 series part number and a UL mark.
As a switching power transformer, the PQ4045 can be built to your design for switching power supplies, AC-DC converters, DC-DC converters and industrial power systems. Electrical and mechanical details are defined together with your engineering team before samples are made.

Product Features
PQ Core Structure
The PQ4045 uses a PQ core shape that surrounds the winding. Core material can be selected for your frequency and loss targets, including a ferrite core transformer configuration where required.
Tape-Wrapped Winding
The winding is covered with insulating tape, and a tape band secures the core halves. Layer structure and insulation are defined in your specification.
Secured Base Assembly
Black fixing material holds the transformer to a base plate, helping keep the assembly fixed during installation and operation.
Built to Your Design
Voltage, power, frequency, turns ratio, inductance, terminals and part number marking can all be customized for your power conversion project.
Product Applications
The PQ4045 high frequency transformer is intended for power conversion in industrial equipment, energy systems and custom power supplies, including:
Final suitability depends on your voltage, power, frequency, thermal and safety requirements. Please confirm these conditions before sample approval.
