Note: 1. This RF MEMS Switch was developed on the assumption of cold switching. Do not exceed ratings by hot switching (greater than 0.5 mA
at 0.5 VDC resistive load).
2. This RF MEMS Switch is easily damaged by static electricity. When handling the RF MEMS Switch, take countermeasures against static
electricity. Contact OMRON for handling guidelines.

Recommended Soldering Method
• The thickness of the solder paste is to be applied between 150 and
200 μm and the land pattern should be based on OMRON's recom-
mended PCB pattern.
• To maintain the correct soldering joint shown in the following dia-
gram, we recommend applying solder with the soldering conditions
shown on the left.
T4
T3
• Check the soldering in the actual mounting conditions before use.
T2
T1
• When washing the product after soldering the RF MEMS Switch to
a print circuit board, use a water-based solvent or alcohol-based
solvent and keep the solvent temperature to less than 40°C.
• Do not put the RF MEMS Switch in a cold cleaning bath immedi-
ately after soldering.

Note: 1. Operate the driving voltage with the high-side switch (Vcont_1 & Vcont_2, not ground).
2. It is necessary to discharge the charge that accumulates in the electrostatic actuator to turn off the RF MEMS Switch because this product
is a MEMS Switch of an electrostatic drive type. Install the electrical discharge circuit in the drive circuit of the RF MEMS Switch with a
resistance of 1 MΩ or less. Without an electrical discharge circuit, the RF MEMS Switch might not turn off, and the contacts could stick.

Safety Precautions
■ Precautions for Correct Use
• Turn off power when doing the exchange and the wiring work of the
RF MEMS Switch.
Long-term, Continuous ON Contacts
• Using the RF MEMS Switch in a circuit where the RF MEMS Switch
will be ON continuously for long periods (more than 24 hours)
(rather than switching) can lead to unstable contacts. If a single-
side stable model must be used in this kind of circuit, we recom-
mend adding fail-safe circuits in case the contact fails.
• Do not touch the terminal of the RF MEMS Switch when energized.
RF MEMS Switch Handling
• Use the RF MEMS Switch as soon as possible after opening the
moisture-proof package (within one week). If the RF MEMS Switch
is left for a long time after opening the moisture-proof package, the
appearance may suffer and seal failure may occur after the solder
mounting process. To store the RF MEMS Switch after opening the
moisture-proof package, place it into the original package and seal
the package with adhesive tape.
Claw Securing Force During Automatic
Mounting
• During automatic insertion of RF MEMS Switches, be sure to set
the securing force of each claw to the following so that the RF
MEMS Switch's characteristics will be maintained.
• When washing the product after soldering the RF MEMS Switch to
a print circuit board, use a water-based solvent or alcohol-based
solvent and keep the solvent temperature to less than 40°C. Do not
put the RF MEMS Switch in a cold cleaning bath immediately after
soldering.
Direction C: 2.0 N max.
• Do not use an Ultrasonic wash.
• This RF MEMS Switch is easily damaged by static electricity. When
handling the RF MEMS Switch, take countermeasure against static
electricity (100 V or less). Contact OMRON for additional guide-
lines.
• When handling the RF MEMS Switch, do not drop.
• Do not apply force resulting in the product to transform and change
in quality.
Environmental Conditions for Usage,
Storage, and Transport
• Avoid direct sunlight when using, storing, or transporting the RF
MEMS Switch and maintain normal temperature, humidity, and
pressure conditions.
• Avoid caustic gases when using, storing, or transporting the RF
MEMS Switch.
Coating
• Do not coat the RF MEMS Switch when it is mounted to the print
circuit board. Do not wash the print circuit board after the RF
MEMS Switch is mounted using detergent containing silicone. Oth-
erwise, the detergent may remain on the surface of the RF MEMS
Switch.
