STOPBAND FREQUENCY CALCULATIONS:
Using part number J87-5M-50-65B, we know that
the filter is a 9 pole TTE-designed lowpass filter.
Scroll down to series number J87. Moving to the
right we find the stopband specification listed as
-60dBc minimum at 1.35 x f -3dBc. Thus, the -60dBc
frequency is at 6.75 MHz (1.35 x 5 MHz).
PART NUMBER DERIVATION:

1) Series, J87 (which has 9 poles)
2) The “T” option specifies a filter witih low THD
for ADC/DAC testing. When selected the
minimum THD is >-80dBc, -96dBc typical.
3) “R” RoHS compliant. Allow for longer lead time.
4) f-3dBc
5) Terminations
6) Case selection from the case selection guide.
“T” option cases are larger than standard.
