PQ32 Ferrite Core SMPS High Frequency Transformer Electronic Low Magnetic Loss
The CHIPSEN PQ3225-133-13122 is a high frequency switching power transformer built on a PQ32/25 ferrite core, engineered for compact SMPS designs that demand low core loss, stable inductance and reliable insulation. The PQ core geometry offers a large winding window with a small PCB footprint, delivering an excellent power-to-volume ratio and better thermal dissipation than conventional EE/EI structures. Every unit is manufactured with UL recognized materials (UL File No. E332338) and 100% electrically tested before shipment.
Key Features
Low magnetic loss - high-permeability PC40/PC44 grade ferrite core keeps core loss and temperature rise low at high switching frequency.
High power density - PQ32/25 core provides a large winding area within a compact footprint, ideal for space-limited power boards.
Reinforced insulation - margin tape + triple-layer insulation structure, high dielectric strength between primary and secondary.
Excellent EMI performance - optimized winding sequence and shielding layer reduce leakage inductance and common-mode noise.
Vertical pin-through-hole design - standard horizontal bobbin with robust copper-plated pins for stable soldering and easy automated assembly.
UL recognized components - UL File No. E332338; RoHS & REACH compliant materials.
Full customization - turns ratio, inductance, pin-out, bobbin and core material can all be built to your drawing or sample.
