Core Materials › Silicon Steel Cores
Split Current Transformer Core
CRGO silicon steel with characteristics of low iron-loss and high permeability in thickness of 0.23mm, 0.27mm. Cores are wound by our independently-developed winding machine and are high vacuum heat treated. Asymmetric cutting is acceptable. They come in shapes of UI, UU, and toroidal with precise dimensions. Mainly used in the current transformers for electricity acquisition and detection. Square and round hole shapes are available.

Therefore, the maximum current measured by the split current transformer is much larger than that measured by the current transformer with a closed structure. For example, the split current transformer core has a wider measuring range. / Non-invasive / Because of the open-close structure, the high precision split current transformer can be clamped directly on the measured conductor, and then the non-invasive measurement can be carried out without cutting off the circuit. / Strong anti-saturation ability / The split current transformer core has a gap which strengthens the saturation magnetic flux density of the core. Besides, the influence of residual magnetism on the split current transformer is lower than that on the closed structure current transformer. These make the split current transformer a strong anti-saturation capability. |

Why Engineers Specify This Part
Every point below is taken from the published data for this part number rather than from a general claim.
Part of a 8 item Silicon Steel Cores range
Changing size later stays inside the same catalogue and the same tooling shop rather than becoming a new supplier search.
RoHS compliant
All products from CB Magnetics are RoHS compliant, which keeps the part usable in EU bound assemblies.
How It Is Made
Tool design, moulding, terminal insertion, assembly, electrical and dimensional test, then packing. The same route applies whether the part is a stock item or a new tool.
- Drawing review and tool design
- Steel cutting on the wire EDM and CNC machines in the tool room
- Injection moulding
- Terminal insertion and assembly
- Dimensional check in the measuring room
- Packing and shipping
Use Guide
Three checks before you commit a board layout or a winding programme to this part.
- Footprint. Match the published pin distance and row distance to your land pattern, then confirm both on the dimensioned drawing.
- Thermal. Check the stated plastic against your soldering profile. Thermoset bodies tolerate solder pot temperatures that melt many thermoplastics.
- Winding window. Confirm the section arrangement and the number of turns your wire gauge needs before ordering the tool or the first batch.

Questions Buyers Ask About This Part
What is the pin pitch and row spacing
The pin geometry for this part is on the drawing rather than in the published summary. Ask for the drawing and it will be sent as a PDF.
Can I get a drawing or a 3D model
Yes. Dimensioned drawings are sent as PDF and CAD files are released on request rather than as an open download. Ask for CAD on WhatsApp.
Are the parts RoHS compliant
Yes. All products from CB Magnetics are RoHS compliant.
Can this part be modified
Custom tooling design and injection moulding is one of our standing services, so pin count section splits and mounting features can be changed on a new tool. See how the tooling service works.
How do I get a price and lead time
Send the part number and the annual quantity. Price and lead time are quoted per part and per quantity rather than published, because both move with the material and the pin count. Send the quantity on WhatsApp.
Send The Part Number And Quantity
Quotes go out against a part number and an annual volume. If you have a drawing instead of a part number send that and it will be checked against existing tooling first.
