Half-bridge transformers boast chip-style construction
HTX7045C Series transformers feature a chip-style construction – a significant advancement over traditional core and bobbin designs that not only reduces the size of the component but also streamlines the manufacturing process, resulting in a more cost-effective solution. It offers low interwinding capacitance (as low as 0.7 pF), making it particularly well-suited for use in […]
TTape: A simple way to monitor Li-ion battery-pack temperature
A set of temperature-triggered switches alerts you to hot batteries. Li-ion batteries can get hot, which can cause failures or worse in the products they power. Thus, it’s important to monitor their temperature and act before damage occurs. You can monitor temperature with a set of thermocouples, scan them, and write software to produce an […]
