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 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).
