Magnetic cores for inductors and transformers
When developing inductive components like transformers and inductors, choosing the right material is the first challenge. There are over a dozen material classes, with a huge variety of sub-classes, brands, grades and types. A developer has to match their applications requirements with the parameters of each material and give consideration to the cost implications.
Common Mode Chokes for EMI filters: cores and components
When designing modern and often complex integrated systems, engineers must take into account the possibility of electro-magnetic interference (EMI), which affects the performance of the system and can lead to a failure to meet regulatory standards. To contain conducted emissions the usual solution is to add a filter at the input stage of your system and common mode chokes (CMC) are the basic component of the filter. This allows the target signal to pass unaffected, whilst filtering out undesired signals. It is important that reliable, functional and affordable materials are used to create these components to avoid the saturation of the magnetic core, allow the correct efficiency in the desired frequency range and set the appropriate differential inductance.

Designing compact product? Then you may want to consider planar magnetic components
Thermal conductive products
High current power conversion produces heat which must be dissipated safely to avoid overheating causing EMI issues or even premature failure of electronics inside the application. Acal BFi can offer market leading thermal interface materials from MTC,that combine high thermal conductivity and low viscosity whilst maintaining insulating properties.
Temperature sensors are used across a range of applications for electric vehicle charging, such as temperature detection of the electric motor, temperature protection of the on-board charger, charging cable and the charging pile as well as battery system management (BMS), making sure to activate an automatic shut-off in case of hazardous electrical faults.
These applications call for sensors that are suited to harsh environments – with a higher tolerance, stability and durability, offering customisation of the sensor in accordance with the varying requirements of shocks and conditions for different vehicles.
With Tewa and Shibaura’s high-quality and sensitive technology, we offer a wide range of temperature sensors with plastic, metal or epoxy encapsulation able to withstand temperatures up to 1000°C, with IP68 rated over-moulded probes offering a level of customisation of housings, coatings and cables that can be designed to meet the most demanding environments.

Current sensitivity components
EV charging systems require the capability to measure current in order to detect uncontrolled situations which may cause permanent system failures.
When power management rating increase, you may need 50/60Hz transformers to connect your charger system to the grid. We offer a specialist range of transformers designed for smoothing in rectifiers, reducing short-circuit currents, AC filtering and high frequency switching.
FLIRs IR sensors have a proven history of being used for human detection and security applications because of their low power consumption and because they are effective night and day in a variety of environmental conditions. However, in an EV application they can also be used to optimise system management, detecting heat spikes and they can be used to improve the accuracy of vehicle detection in automated EV charging facilities.
Our specialist products provide the EV charging systems and vehicles with precise, real-time, distance measurements, the multi-segment optical sensing technology provides narrow to wide fields of view with lateral discrimination, enabling multiple object detection and distance measurements.
