Does Murata show every part number they make in their catalogs or on the web page?
No, Murata (and other suppliers) have various stages of product development and design reviews prior to releasing a product to mass production. Also, many products (such as microwave filters, VCO's, Sensors, etc.) are very custom in nature to meet specific needs of the customers' design. For these reasons, it is not always possible or practical to show all possible part numbers in catalogs or on our web page.
