Choosing a resistor for pulse applications can be tricky business. What is the magnitude of the pulse? How long does it last? How often does it repeat? What is an acceptable resistance range? And then there are the multiple resistor technologies to consider. A typical...

Precision shunts are very precise resistors inserted into a circuit in order to measure the current flowing through that circuit. The shunt does this by providing a very small voltage drop across its resistance proportional to the current flowing through the shunt. ...

Heat dissipation is a key factor in the design of a power system; in a world where the trend is for more power in a smaller space, are TO-style packages still the best solution? TO packages were originally intended for discrete transistors, in fact TO stands for...
