102, 104, 106 Picture
102, 104 and 106 Series

Key Features:

Output power models from 5 to 1,500 milliwatt level available.
0.5" long pin type (.025" dia. on 102 series, .032" dia. on 104 & 106 series), P.C. board mount.
Bifilar winding technique used on center tapped units for balanced resistive and capacitive characteristics.
Rugged black epoxy potted construction produces a completely sealed unit withstanding severe environmental conditions including those of MIL-T-27 (Grade 5, Class S).
For the more economical open type P.C. mount types please refer to the 148 & 149 series.
Peak working voltage rating of: 100V (102 Series) & 200V (104 & 106 Series).
Referring to figures 1-9, if connection is not used - no pin will exist.

NOTES:
*1) Where primary is center-tapped, this figure is the maximum unbalance
*2) When operating at impedances below normal, power capability and the frequency spectrum are proportionally lower, conversely, at higher impedances power capability and frequency spectrum will be proportionately higher.
*3) Insertion loss measured at 1000 Hz.
*4) Approximate frequency in hertz at which the output, at rated load and D.C. unbalance, is 1 db below the 1000 Hertz rating. The high frequency roll-off point exceeds 20 Khz. (Above 35 Khz. in most types).
