All the products listed in the catalog are available from […]
Power-supply noise, Part 2
Part 1 looked at the basics of noise, especially concerning power supplies. There are two noise sources which are not as obvious to many engineers as noise that results from the switching action of the power supply: differential mode noise and common-mode noise. These two noise modes have different causes and thus different solutions Q: […]
Power-supply noise, Part 1
“Noise”—perhaps nothing worries design engineers as much as the implications of this single five-letter word. There are good reasons for this worry. Noise is often unpredictable; may come from internal and somewhat controllable sources, or external impossible-to-control sources; it can affect performance accuracy and consistency; it can cause products to not meet their target design […]
New transformer, toroidal packages highlighted in power components catalog
Wurth Electronics Midcom has announced the publication of the newest Capabilities Catalog. This comprehensive catalog includes capabilities for the design of custom transformers and toroids, the focus of the company for over 25 years. This catalog offers customers over 100 packages as the foundation for a custom design. Two new transformer packages, EPC40 and RM8, […]
SMD transformers sport 1.5 kV isolation voltage, low core losses
Würth Elektronik eiSos presents a new line of transformers for SMT assembly – WE-FLEX HV (Flexible Transformer High Voltage). Like the WE-FLEX series of transformers, these excel because of their flexible capabilities in various applications making them ideally suited for fast prototyping.
