The design is a PCB printed coil in a 4-layer board. The outside diameter of the coil is about half an inch.
The trace can be touched right after the pulse. It doesn't get extremely hot. When I said sporadic, I meant that the pulse is sent once every 10 or 15 minutes. So, there is plenty of...
Hi,
I have a design with a 6 mills trace that takes just one 1.6Amps pulse for a period equal to 100 mS. This pulse is very sporadic. The trace gets very hot momentarily, but the heat dissipates quickly. The design works fine, but I'm concerned that it might fail over time. I can't use a bigger...
FVM,
Thank you for your help. We have a four by four antenna array with 16 coils in it. Our goal is to use 4 switches on two sides for a total 8 switches to control the 16 coils. We want to use the matching network that comes in the Seeedstudio NFC RFID module. I think that 8 relays will work...
Hi all,
I have an array of 16 antennas (coils) that I would like to multiplex using some kind of analog switches or multiplexers. I'm using the Seeedstudio NFC RFID module and it works fine with one antenna connected to it.
I have tried using the LCA110 MOSFET optocouplers, but it works okay...
