Surface Mount - 2000W >2.0SMB series
Description
The 2.0SMB series is designed specifically
to protect sensitive electronic equipment
from voltage transients induced by lightning
and other transient voltage events.

Solder Reflow Recommendations
●Recommended reflow methods: IR, vapor
phase oven, hot air oven, wave solder.
●The device can be exposed to a maximum
temperature of 265°C for 10 seconds.
●Devices can be cleaned using standard
industry methods and solvents.
Notes: If reflow temperatures exceed the
recommended profile, devices may not
meet the performance requirements.
