Temperature sensor: TDK launches a new NTC thermistor for measuring the temperature of laser diodes and optional gold wire bonding
2023-09-09
Optional gold wire bonding
The tolerance of resistance and B value is within ± 1%, ensuring accurate temperature sensing height
Used to measure the temperature of laser diodes in optical communication transceivers and LiDARs
TDK Corporation (TSE: 6762) has launched a new NTCWS series of NTC thermistors with optional gold wire bonding. This product series will begin mass production in September 2023. These bondable NTC thermistors can be installed inside the package through gold wire bonding, enabling highly accurate temperature detection of optical communication laser diodes (LDs).
In optical communication transceivers, the use of LD devices is constantly increasing, with 5G and LiDAR used to measure vehicle spacing being typical representatives. Due to the fact that the wavelength of LD varies with temperature, controlling the temperature of LD is the key to improving its performance.
TDK's newly launched NTCWS series temperature sensors support extremely small resistance and B value tolerance (± 1%), and can be installed near LD through gold wire bonding to ensure high accuracy of temperature sensing. The NTCWS series thermistors adopt a compact lead-free design and can operate in the temperature range of -40~125 ℃. TDK first released sensors with a B value of 3930 K ± 1% (NTCWS3UF103FC1GT and NTCWS3UF103HC1GT), and plans to further release products with other features in the future.
TDK is committed to continuously improving temperature sensor products for industrial and automotive applications, and will continue to expand its NTC thermistor product portfolio to meet market demand.
Main applications
LD temperature sensing for optical communication transceivers and LiDARs
Main features and advantages
Supports gold wire bonding and can be installed inside LD packaging
