Ferroxcube – the founder of ferrites
Building on the heritage of Philips Magnetic Components, Ferroxcube offer customers the highest level of support in the development of their new innovative design.
Converters operate at a wide switching frequency range, depending on the voltage, power and cost constraints. For each range, Ferroxcube offer specific materials working from just a few kHz (inverters, high voltage systems) to tens of kHz (consumer and computer SMPS), hundreds of kHz (high-efficiency, compact converters) and even MHz.
Other parameters used to select the correct material include core loss at working temperature. While standard material for industrial equipment is optimised at around 100°C, there are applications that require steady loss curves in fluctuating temperatures ranges as wide as 20°C-100°C (eg handheld converters) or 60°C-140°C (eg automotive).
These materials are available in most of the shapes we offer (toroids, E cores, EFD, RM, pot cores, etc)
Electro-magnetic interference (EMI) severely affects the operation of electronic equipment. Ferrites exhibit excellent EMI protection against common mode and differential conducted noise – their insertion loss is proportional to frequency and thus lets the lower frequency signals pass, but shows high attenuation to the high frequency noise.
Ferroxcube offers a wide range of materials for different frequency bands, thermal conditions and type of noise to be suppressed, with complete data and characterisation to ease the design process.
The main applications for signal processing are telecom line filters, proximity sensors, signal and pulse transformers, delay lines and antennae.Ferroxcube offer outstanding technologies and products for telecommunications equipment manufacturers. For example, Ferroxcube have introduced the high-permeability material 3B46 for filter applications with high bias current. In combination with the virtually unlimited core shape variety offered by Ferroxcube, almost any technical challenge can be addressed.
