Application Notes
resonators, which have extremely narrow spacings
between their interdigitated electrodes, shall be free from
high voltage spikes such as “Electrostatic Discharges,” to
prevent failures and damages of the devices. The
following countermeasures are recommended: (a)
ground human body via earth band; (b) set electricity
rejecting sheet to working table.
impression/application of line voltage to the SAW filters
and resonators shall cause short circuits between their
interdigitated electrodes.
resonators shall not be operated beyond the specified
“Operating Temperature Range” in the catalog and the
specifications.
not be operated beyond the specified “Maximum R.F.
Input Power Ratings” listed in specifications.
the SAW filters and resonators shall cause failures and
deterioration of the devices. DC voltage shall be cut by a
capacitor.

characteristics of the devices, and shall not be applied to
the SAW filters and resonators.
the SAW filters and resonators shall not be soldered for
the purpose of grounding. Soldering to the metallic cases
may cause deterioration or damage in mechanical and
electrical characteristics.
resonators shall not be operated and stored under the
following environmental conditions: (a) exposed directly
to water or salt water; (b) exposed directly to sunlight; (c)
under conditions of humidity and dust; (d) under
conditions of corrosive atmosphere such as hydrogen
sulfide, sulfurous acid, chlorine, or ammonia.
