In the 1940s radio was an important means of communication. Super heterodyne radio used Murata’s tubular 500pf ceramic capacitors with titanium oxide as dielectric material for temperature compensation.
Murata Manufacturing – Electronic Components
Passive components like Capacitors, Resistors, Thermistors, Coils(Inductors), Delay Lines, Resonators, Noise Suppression Products and EMI Suppression Filters.
Audio Visual Parts like Spherical Speaker Products, Sound Components Filters, Modules for Audio Visual Equipment,
They also have Components and Modules for Communication Equipment. Special Sensors and Optical Products.
Wireless Products – Murata Wireless Connectivity Products and Platforms
Murata RF modules are designed to simplify wireless development and certification by minimizing the amount of RF expertise you need to wirelessly enable a wide range of applications.
Reasons for requiring EMI suppression filters
Chapter 1 describes the reasons for using EMI suppression filters, and explains how shields and filters used for electromagnetic noise suppression work.
They manufacture and market electronic components, modules and systems. The product line include SAW components, EMC Components, ceramic components, capacitors and inductors.
Epcos AG – Capacitors EMC SAW Components
“SAW components (surface acoustic wave components), integrated radio frequency modules are key components of modern information and communications.”
TDK Corporation has extended its range of EPCOS power factor controllers. The new BR7000-I controller is designed specifically for single-phase networks and combines all the performance features and functions of the proven BR6000 series with the benefits of the BR7000 controller.
The controller has 12 or 13 outputs. The message and alarm relay parameters may be programmed to open or close.
