  Why Choose Epoxy Potted Encapsulated Transformer For Industrial PCB Projects When designing reliable power circuits for industrial, medical and cabinet‑mount devices, component stability against moisture, dust and vibration becomes critical. An encapsulated transformer , also known as epoxy potted transformer, solves many environmental challenges compared with open‑frame transformers. A custom encapsulated transformer is fully filled with epoxy resin. The potting compound wraps the EI core, windings and pins completely. This structure locks internal components firmly, avoids winding displacement under shock or continuous vibration. The epoxy potted PCB‑mount EI power transformer is one of the most popular models. Designed for direct PCB mounting via pin terminals, it saves cabinet space for compact equipment. It belongs to encapsulated low frequency transformer , mainly used for AC‑AC power isolation and voltage conversion instead of high‑frequency SMPS tasks. Core benefits of...

Chassis Mount Transformer vs PCB Mount Transformer: How To Choose

图片
  When designing power circuits for industrial cabinets, audio equipment, and fixed‑installation electronic devices, selecting the right transformer mounting style directly impacts mechanical stability, heat dissipation, noise performance and long‑term reliability. Two widely‑adopted solutions are chassis mount transformer and  encapsulated  PCB mount transformer . Understanding their strengths will help you pick the correct component for your hardware. A custom chassis mount transformer is fastened directly onto equipment housing, cabinet chassis or metal frame through pre‑drilled mounting holes. It does not rely on the printed circuit board to bear weight. This structure is ideal for medium‑to‑high power applications. The weight and vibration stress are transferred to the solid chassis instead of fragile PCB traces. One typical application scenario is high‑fidelity audio hardware. An audio chassis mount power transformer focuses on low hum noise, stable voltage outp...

What Is Custom Flyback Transformer & Its Applications in SMPS

图片
  A flyback transformer acts as a coupled inductor used in isolated SMPS circuit topologies. It stores and transfers energy during switching cycles, differing structurally from ordinary high frequency power transformers. Many circuit engineers prefer custom-designed flyback transformers for SMPS power circuits to meet non-standard design requirements instead of selecting universal stock components. Ready-made magnetic components frequently fail to meet special demands including winding ratio, stray inductance, pin arrangement and creepage distance. We are an experienced manufacturer offering tailor-made high frequency magnetic parts. Our engineering team develops custom ferrite flyback transformers for industrial switching power supplies with EE, PQ and ETD core options for various power levels. These customized flyback magnetic components are widely deployed in multiple SMPS scenarios: • AC-DC adapters and lithium battery charging modules • Constant current LED driver power...
