Toko Helical Filter
Hello,
I need help in identifying the pin out of a Toko Helical filter 252MX-1551A. (7HW series) This is a 4 pin device. Pins 1, 8 is the input and Pins 4,5 is the output but the filter pins are arranged such that it can be fitted either way round. Any information will be greatly appreciated. Regards Surinder |

Re: Toko Helical Filter
Surely the design of these is symmetrical, so it can be inserted either way?
