PCB Mount Current Transformer Models

Incorporate a Compact, Reliable PCB Mount Transformer

Low Profile PCB Mount Current Transformer Options

We offer a special line of toroidal transformers that come fully encapsulated in a plastic case. This toroidal transformer line is designed for through-hole PCB mounting, and each one comes with a built-in central screw receptacle that will accommodate M4/M5 machine screws or self-tapping screws. This allows you to secure the transformer to the board prior to the soldering process.

Our case design allows space for you to incorporate other components with the transformer to form a homogeneous unit. Common additions include PTC thermistors, fuses, re-settable thermal switches, rectifiers and voltage regulators.

In addition, the transformer can withstand elevated ambient temperatures of up to 70˚C.

PCB Mount Toroidal Transformer Advantages

  • Low profile
  • Low magnetic field radiation
  • Acoustic noise virtually eliminated
  • Compact size
  • High efficiency
  • Low leakage losses
  • Four kV isolation between primary and secondary windings

We manufacture each low-profile PCB mount current transformer to the highest quality standards in an ISO 9001 approved facility.

All PCB mount transformer models comply to standards UL 5085 and VDE 61558 (except for all 2 x 22 V models), and they also bear the CE mark. All models are designed and built to meet Class F (155˚C) insulation system requirements.
