High Value Resistors in Thick film technology is a Specialization. Products include precision and power resistors, special Ceramic Chip Capacitors, Temperature Sensors and other High Grade Passive Electronic Components.
In the expansion of the existing types of High Value and High Voltage resistor series, SRT is presenting at electronica 2006 under the designation HVR25 a leaded resistor, which has a working voltage of 15kV at a length of only 25mm.
By means of an optimized design for high working voltages, SRT has succeeded in realizing at this length and a width of 9 mm this improved version of High Voltage resistors. Compared with the type HVR30 with 30mm length, the working voltage could be increased by 5kV and the Voltage Coefficient (VCR) reduced by about 50%.
They develop and manufacture soft magnetic components and materials. These are used in the Products in Power Electronics and RF Communications. A leading world supplier of precision, high permeability magnetic components and materials to the electronics industry.
Made from MnZn, ferrite cores offer economical solutions for high frequency power transformers and inductors, EMC filters, and other applications.
Ferrites are dense, homogenous ceramic structures made by mixing iron oxide with oxides or carbonates of one or more metals such as zinc, manganese, nickel or magnesium.
Ferrite ETD Cores
ETD cores are an economical choice for transformers or inductors. ETDs offer a round centerpost for minimum winding resistance. Dimensions are optimized for power transformer efficiency. Typical applications of Magnetics ETD cores include differential mode inductors and power transformers.
CWS provides full service from design, prototyping, pre-production run to volume production. They are experts in designing and manufacturing of magnetic components such as inductor, choke, coil and transformers. These magnetics are designed with ferrites, iron powder, MPP, sendust or high flux cores in all shapes and sizes.
At CWS we understand that that common inductor coil or chokes need to be customized in order to provide top performance within a circuit. Our designers and engineers can provide the technology needed to ensure your coil can combat EMI issues and also interference with other circuits.
