John Diaz’ Schematic Dave Curtis’ Schematic Rev3Mystery parts 1

These L3,L4 (L3,L8 in original) are hand wound coils that need to be specially made here at SSL.

Mystery part 2

Where do we order this oscillator? The answer is “Dorothy Knows”

Other questions!• Caps 10-32 not found in 1206 package, what is comparable?

Ans: Tantalum Caps will never be found in that package, find another.

• Resistors listed as RWR81 (R41,19,21,44,49) – how do we translate that into a package size? Answer: RWR81 is a milspec package, look for commercial part possibly in 2815 package.

• 2 caps 0.01 pF @ 50V. 10 pF @ 10V, can’t find those anywhere in Digikey or other cat. Answer: 0.01 pF @ 50V is a misprint in the new schematic, should be 0.01 microF. The other one does not have to be 10V it can be 100 and that can probably be found.

Where is the Input voltage on pin 4 of U25 in the Diptrace schematic?

Need 8v HERE!!

Question

Why is the pull up resistor connected to On/Off toggle instead of Vin or missing on some of the FPF2106 load switches in both schematics?
