    Suitable replacement for a large Siemens capacitor in an old IBM XT power supply

    The printed nominal capacitance value, is not the actual value capacitance and will vary depending on circuit frequency. As long as you’re working voltage (WV)is the same or more than the original specifications. You have nothing to worry about you are well within tolerance.

    Found problem in Kenwood KR-V95R

    Replace with two 6800 microfarad capacitors connected in series which will cut the capacitance value in half and will equal 3400uf.

    high voltage electrolytica capacitor vs oil filled

    All caps & BOLD means you’re yelling… Disrespectful when you are addressing the @AnalogKid. An analogy would be when playing poker, (five cards stud) and you’re holding aces and eights. Which is, of course…“the dead man’s hand.”

    Television reception antennas farce...

    TV reception antennas are nominally designed for either 75-ohm unbalanced or 300-ohm balanced standard impedances. An antenna’s impedance plot demonstrates how its input resistance and reactance vary wildly across different frequencies. While exact numbers vary by element length, all standard...

    Ultra-Low Power and Long-Range Design of LoRa Modules

    I would agree with you but in doing so we would both be wrong.

    Ultra-Low Power and Long-Range Design of LoRa Modules

    Sure if you wanna blinking LED Several kilometers away! Do you have a question? Data rates are often in the hundreds of bits per second because of the small data packets transmitted asynchronously, latency is to be expected due to limited network capacity transmitted on unlicensed bands...
