    Intermittent linear motion from rotary motion, very low duty cycle?

    Hi all, Before I start, this isn't for a production system, nor for a system intended for production, but it is a bespoke system. So if I have to machine a weird-looking part, that wouldn't be an obstacle. Here is the application: I have a series of 1/8" horizontal shafts, stacked vertically...

    Replacement for 2N5160 transistor?

    It seems I'm about to answer my own question, sort of. Texas instruments makes a THS4041/2 opamp (see http://focus.ti.com/lit/ds/symlink/ths4042.pdf for datasheet) which has a gain-bandwidth product of 165 MHz, power supply max +/- 15V, power dissipation of at least 1W (with proper PCB...

    Replacement for 2N5160 transistor?

    Hi felixc, The working voltage is 24 volts. The ZTX451 is okay, but the fT is a bit low for the application, as you've pointed out. Since we're only dealing with a x2 amplification at max 50 MHz, an fT of 150 MHz should probably work for sine wave output, but it would distort the triangle and...

    Replacement for 2N5160 transistor?

    Hi all, In trying to repair an HP 8165A signal generator, I found that one of the output transistors is bad. HP's test equipment division, which is now Agilent, had the wonderful corporate mentality of using custom components, even going to the extreme of manufacturing their own transistors...
