RECOMMENDED
OPERATING CONDITIONS (Zs = ZL = 75Ω)
Note:
1. Test Conditions: 110 Channels, 10 dB tilted across the band.
1. The space between PC board and root of the lead should be
kept more than 1 mm to prevent undesired stress on the lead and
also should be kept less than 4 mm to prevent undesired parasitic
inductance.
Recommended space is 2.0 to 3.0 mm typical.
2. Recommended torque strength of the screw is 59 to 78 Ncm.
3. Form the ground pattern as wide as possible to minimize ground
impedance. (to prevent undesired oscillation)
All the ground pins must be connected together with wide ground
pattern to decrease impedance difference.
NOTES ON CORRECT USE
This product should be soldered in the following recommended
conditions. Other soldering methods and conditions than the
recommended conditions are to be consulted with our sales
representatives.

Hour: Within 2 sec./pin
Note.
1. The point of pin part heating must be kept at a distance of more
than 1.2 mm from the root of lead.
1. Measured per US standard methods and procedures (using selective level meter).
