Resistor Value for Measuring Leakage Current

Furor and controversy are words which describe the process by which standards committees decide the value of the resistor in the leakage current measuring network. However, the different specified resistor values create no more than a 6.25% error for the value of the leakage current.

Things You May Not Have Heard About Shielding

What determines how effective a cable shield is going to be? And how does the decision to ground or not ground a shield impact its effectiveness? Fortunately, there is a well-developed theory of shielding, which will be discussed as a way to get a general understanding of what can be expected of shield performance. But there’s more to it.

The “Real” Cost of ESD Damage

1406 F4 cover Anyone who has worked in quality or reliability in a large corporation knows that developing and presenting credible failure cost information can be difficult. This is particularly true for ESD, where the events and their effects are invisible and not nearly as well understood as other more obvious classes of failure, such as mechanical or contamination.
