Single-phase EMI filters for AC and DC applications
TDK Corporation has expanded its portfolio of single-phase EMC filters with the B84742A*R725 series. These components serve AC as well as DC applications up to 250 V and rated currents from 6 A to 30 A. This means they can be used for increasingly popular DC infrastructure in the industrial and building sectors. Available in […]
Modular power EMI filters meet MIL-STD-461
Spectrum Control Inc. introduces a family of modular power EMI filters bringing high performance and design flexibility to a variety of MIL-STD-461 designs with size, weight, power, and cost (SWaP-C) requirements. The chassis mount filters have a wide -55° to 75° C operating temperature. Superior mid- and high-frequency attenuation up to 1 GHz (common mode) is achieved 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 […]
Power sequencing — options and tradeoffs: part 2
Proper sequencing of the multiple power rails in a system is a critical function and can be accomplished using different approaches. For applications with many rails, complicated sequencing requirements may require many additional components. There are two paths to resolving this advanced sequencing challenge, both offering the needed capabilities. One is based on a user-programmed […]
