Shielded vs. Unshielded Square Magnetic Field Loops for EMI/ESD Design and Troubleshooting

In this article, square unshielded wire loops are compared to shielded solutions including simple techniques to build them in your lab. Some examples are included to show that unshielded loops often work as well as shielded loops in some applications, especially for injecting signals into circuits.

Measuring Breakdown Voltage With an ESD Simulator

Special simulator characteristics are needed Measuring high voltage breakdown has many uses including tracking down the cause of equipment failure and ascertaining compliance to safety standards. Some ESD si... Read More...

Destroying Electronic Components from Across the Room With ESD

(Today’s sensitive components are really sensitive!) Electronic components are getting smaller and more sensitive every day, and with this comes a greater possibility of damage from electrical stresses in th... Read More...

Electromagnetic Interference (EMI) Effects on Measurement Equipment – ESD Effects on Oscilloscopes

When debugging designs or making electrical measurements of noise, especially ESD, we often assume the only equipment in the room that works perfectly is our measurement equipment. This assumption can be wrong ... Read More...

Effect of High Voltage Pulses on Resistors – ESD and EFT

Carbon composition resistors work very well under pulsed conditions, but are getting difficult to obtain. Results of tests run on several modern film resistors using high voltage pulses are presented. For the c... Read More...

Measuring Capacitor Self-inductance and ESR

Technical Background The parasitic parameters of a capacitor, that is its equivalent series resistance (ESR) and its inductance, affect the way the capacitor performs in circuits. Some applications are very se... Read More...
