TDK Corporation (TSE: 6762) announced the introduction of the new NTCWS series of NTC thermistors with gold wire bonding. These bonding NTC thermistors can be installed in packages via gold wire bonding to enable high precision temperature detection of laser diodes (LD) for optical communication. The series will begin mass production in September 2023.

The use of LD devices in optical communication transceivers is increasing, represented by 5G and LiDAR for distance measurement between vehicles. Since the wavelength of LD varies with temperature, controlling the temperature of LD is the key to improve its performance.

TDK's new NTCWS series temperature sensors support narrow tolerances (± 1%) of resistance and B values, and can be mounted near the LD using a gold wire joint for high precision temperature sensing. The NTCWS series thermistors have a compact, lead-free design and can withstand operating temperatures from -40 to 125 °C. TDK has initially released sensors with a B value of 3930 K ± 1% (NTCWS3UF103FC1GT and NTCWS3UF103HC1GT) and plans to release more products with additional features in the future.

TDK is committed to improving temperature sensor products for industrial and automotive applications and will continue to expand its NTC thermistor portfolio to meet market demand.

Main application
LD temperature sensing for optical communication transceivers and liDAR
Main features and advantages
Supports gold wire bonding that can be installed inside the LD package
Narrow tolerance for resistance and B values (± 1%)
