Wire-bondable NTC thermistors are compact temperature sensors that can be placed directly next to heat-generating components in power modules, overcoming the placement limitations of conventional SMD and MELF types. For SiC power modules, key selection criteria include 200°C heat resistance, AEC-Q200 compliance, a top-side two-electrode structure, process compatibility, and B-constant accuracy.
TDK offers a broad lineup, including the NTCWS series.

With the increasing output of Electric Vehicles (EV), the fast charging of power devices has increased in importance. The management of 'thermal management' that captures rapid temperature changes is critical to performance and safety. This article introduces our 'High-Speed Response NTC Thermistor,' which overcomes the limitations of conventional case-type NTC thermistors by using a unique structure that integrates a molded thin body substrate onto the heat-receiving surface. Its compact and thin design, allows it to achieves both excellent thermal responsiveness and reliability. It enables high-precision temperature measurement in confined areas of automotive battery packs and industrial equipment.

Degradation of accuracy due to stray-field noise is a common problem for magnetic field sensors. Securing a distance between the source of stray field and the sensor, or placing a magnetic shield, are major restrictions on design and lead to higher system costs. In addition, it was difficult to select an appropriate design while adjusting the balance between compensation effectiveness and cost. As a solution, TDK proposes a method of suppressing magnetic stray-fields using multiple sensors. In the "summary of compensation measures" below, the effect of stray field is compensated by using the output difference of two sensors that output opposite phases to the magnetic field signal. By selecting the number of sensors to be used, rational countermeasures can be selected while considering the expected stray field and allowable angular error.

As data centers and communications networks evolve to support faster speeds and greater bandwidth, the demand for high‑performance optical transceivers is surging.
