Compact Bondable Thermistor Solutions for High-Precision Thermal Control in Optical Transceivers
TDK’s NTCWS series bondable thermistors deliver compact, high-precision temperature sensing for optical transceivers. Designed for wire bonding near laser diodes and driver ICs, they enable proactive thermal control, stable wavelengths, longer life, and reliable performance in demanding data center networks.
NTC sensor elements are the functional basis for all kinds of NTC temperature sensors in all applications. TDK offers epoxy resin and glass-encapsulated elements for temperature ranges of up to 160°C and 300°C, respectively, as well as unleaded NTC chip thermistors for temperature measurement, e.g. in IGBT modules. These sensor elements, which are available with and without insulated leads, feature fast response times and very precise measurements.
As data centers and communications networks evolve to support faster speeds and greater bandwidth, the demand for high‑performance optical transceivers is surging. With the shift toward higher output and compact, high‑density designs, precise thermal management has become a critical factor in maintaining system reliability and performance. This article introduces TDK’s bondable NTC thermistor family—engineered to meet the thermal challenges of next‑generation optical transceivers. We outline the key features, product options, and practical advantages these NTC thermistors provide to design engineers focused on innovation, operational stability, and long‑term reliability.
In recent years, optical transmission systems have been adopted at high rate because of the increase in capacity and speed of communication.
Among them, a semiconductor laser that is positioned as an important component requiring a temperature sensor to keep the ambient temperature constant. A thermocouple can be used as a temperature sensor, but the NTCWS series of NTC thermistor is more suited to this application.
The NTCWS series can be mounted by wire bonding, achieving small size, high accuracy and unquestionable reliability.
