Component Specifications (2004, 2005, 2006, 2007)
The component specification gives the value of the component when the connector is disconnected. Where no value is given, it is not possible to measure a relevant value at the component.
The number to the right of the voltage value indicates the terminal pin on the component to which the value refers.
