TDK Corporation (TSE:6762) has announced the introduction of its new NTCWS series of NTC thermistors, available with Au wire bonding. These bondable NTC thermistors can be mounted with Au wire bonding inside the package for highly accurate temperature detection of laser diodes (LDs) used for optical communication. Mass production of the product series began in September 2023.

The use of LD devices in optical communication transceivers is increasing, as typified by 5G and LiDAR used for inter-vehicle distance measurement. Since the wavelength of LDs changes with temperature, controlling the temperature of LDs is the key to improving their performance.

TDK Corporation (TSE:6762) presents a development starter kit for fast haptics prototyping. It gives mechanical designers and engineers first impressions of the haptic feedback with PowerHap™ piezo actuators, shows how the mechanical integration works, and provides a reference design, which can be adapted to various applications. PowerHap piezo actuators offer an unprecedented quality of haptic feedback based on their unrivaled performance of acceleration, force, and response time. Example applications include automotive (e.g., steering wheels, displays, dashboards, buttons), smartphones, displays and tablets, household appliances, ATMs and vending machines, game controllers, VR gloves, industrial equipment, and medical devices.

TDK Corporation (TSE:6762) presents HVC27 (B88269X*), its new generation of high-voltage contactors that can safely and reliably switch off continuous DC currents of 300 A to 500 A and operating DC voltages of up to 1000 V in lithium-ion batteries in 20 ms or less, depending on the type. This is made possible by the gas-filled ceramic arc chamber which is also used in the other HVC types from TDK. Completely new is the optional Hall-effect sensor for the auxiliary contact. It is used to detect the switching state of the main contacts. The bidirectional design allows only one HVC27 to charge and discharge batteries as well as to power motor drive systems and do regenerative braking (recuperation).

TDK Corporation (TSE:6762) presents new series of extremely compact TVS diodes with parameters matched to the various ports of the USB-C port as well as other high-speed interfaces. TVS diodes with very low parasitic capacitance values and low clamping voltage are required especially for the high-speed ports (Tx / Rx) of USB-C, which operate at up to 40 Gbit/s with USB4 version 1. The B74111U0033M060 and B74121U0033M060 types are suitable for this purpose, with very low capacitance values of 0.48 pF and 0.65 pF at 1 MHz, respectively, which means that signal integrity is not compromised. The clamping voltages are only 3.8 V or 3.9 V with an ITLP of 8 A. The protection devices are designed for ESD discharge voltages of up to 15 kV. These TVS diodes are manufactured in the extremely compact WLCSP 01005 and WLCSP 0201 packages and are extremely flat with heights of 100 µm and 150 µm respectively. This means that the TVS diodes can also be integrated into USB-C SIP modules.
