In this, the final article in the series on protection components, we note that Epcos offers not only the world's largest selection of EMC components, but also a full range of EMC services, including its own accredited test laboratory.
In terms of EMC filters, Wolfgang Sammet, head of the filters business unit at Epcos says: "The part played by EMC filters as protective components is becoming more and more important. In industrial electronics, for example, they protect networks against interference emitted by converters and other equipment operating at high frequencies and pulses with steep edges. What is more, Epcos is working together with 30 accredited test houses across Europe. This partnership is currently being extended to more than 100 test houses."
To summarise what has been covered in this series we see that as a large world supplier of protective components for electronics, Epcos offers its customers tailor-made, economical, reliable and innovative solutions. The range of protective components includes:
* Arrester-varistor hybrids.
* EMC filters for up to 2500 A, designed for all network types.
* Gas-filled surge arresters.
* NTC thermistors, telecom pair protectors.
* PTC thermistors, including SMDs.
* Radial-lead disk, block, strap and energy varistors, AdvanceD/SuperioR series, special varistors for telecom and automotive applications, EnergetiQ series.
* SMD varistors in multilayer technology, special multilayer varistors for the mobile phone market, CeraDiodes, highspeed multilayer varistor series.
