1. Some people say that capacitive reactance cancels out inductive reactance, so the impedance of an LC circuit is 0 Ω to its resonant frequency (not accounting for wire resistance).2. Others say that...
good afternoon. is it possible to make a copy of a printed circuit board from a ready-made sample? small changes will be required to the finished product.I send the sample in the attached photo.if req...
How much does using microvia in my board design at to the manufacturing cost?I don't see micro via as an option in the instant quote process.My board is 6 layers, standard 10cm x 20cm.
I'm playing with a 6AR6 design right now running at 400V B+, and am worried about damaging the 300v max input triodes. The operating point is closer to 150, but ofc they will be exposed to the ful...
I am going to make an arduino project which uses a 0.5W speaker, attached to PAM8403(3W amplifier). Can I directly connect them or should I use a resistor?
I am designing a 2-layer PCB, the bottom layer is GND and the top layer is signal and power. The PCB has some sensors and an arduino, also the I2C is used.I'm learning but I am confused about how ...
Hey guys! I'm making a digital power logger and I was wondering if I should add a linear regulator after a switch-mode converter to make the signal less noisy and more stable or should I stick to ...
I have a power supply that provides +36V DC and -36V DC to power the amplifier, but I also need to supply positive and negative voltage to op amps (in an active crossover before the amplifier). Should...
Hello,How should I connect the thermal relieve pad on a CREE led (XPGDPR-L1-0000-00F01) to the center footprint of the aluminium board?How should I make this connection, so that the pad is soldered co...
