Precautions
Correct Use
Long-term Continuously ON Contacts
Using the Relay in a circuit where the Relay will be ON continuously
for long periods (without switching) can lead to unstable contacts
because the heat generated by the coil itself will affect the insulation,
causing a film to develop on the contact surfaces. Be sure to use a
fail-safe circuit design that provides protection against contact failure
or coil burnout.
Seal integrity during cleaning will last 1 minute at 70°C. Complete
cleaning within these conditions.
Micro Strip Line Design
It is advantageous to use the Micro Strip Line in high–frequency
transmission circuits because a low-loss transmission can be con-
structed with this method. By etching the dielectric base which has
copper foil attached to both sides, the Micro Strip Line will have a
concentrated electric field between the lines and ground as shown
in the following diagram.
Lines with impedance Z
Ground pattern
Dielectric base
(dielectric constant: εr)
The characteristic impedance of the lines ZO is determined by the
kind of base (dielectric constant), the base’s thickness, and the
width of the lines, as expressed in the following equation.
ZO = 377
εr
W
H
1+
2H

1+In
πW
H
W: Line width
εr: Effective dielectric constant
H: Dielectric base thickness
The copper foil thickness must be less than H.
The following graph shows this relationship.
www.DataSheet4U.com
For example, when creating 50-Ω lines using a glass epoxy base
with a thickness of 1.6 mm, the above graph will yield a w/h ratio of
1.7 for a dielectric constant of 4.8. Since the base thickness is
1.6 mm, the width will be h × 1.7 2.7 mm.
The thickness of the copper foil “t” is ignored in this design method,
but it must be considered because large errors will occur in extreme
cases such as a foil thickness of t w.
Furthermore, with the Micro Strip Line design, the lines are too
short for the G6Y’s intended frequency bandwidths, so we can
ignore conductive losses and the line’s attenuation constant.
The spacing of the Strip Lines and ground pattern should be
comparable to the width of the Strip Lines.
Design the pattern with the shortest possible distances. Excessive
distances will adversely effect the high-frequency characteristics.
Spread the ground patterns as widely as possible so that potential
differences are unlikely to develop between the ground patterns.
To avoid potential short-circuits, do not place the pattern’s leads
near the point where the bottom of the Relay attaches to the board.
Bending the Micro Strip Line

Elbow
Clip the corners.
45°C
When the lines must curve, an elbow can be used as shown
in the diagram. A distance (D) between the lines of approxi-
mately twice the line width is sufficient.
Relay Handling
When washing the product after soldering the Relay to a PCB, use a
water-based solvent or alcohol-based solvent, and keep the solvent
temperature to less than 40°C. Do not put the Relay in a cold
cleaning bath immediately after soldering.
