Reference
Only
16.2. Products should be used at rated voltage or less and rated current or less.
16.3. Products should not be applied for the absorption of surge which have large energy (ex. induced lighting
surges, switching surges) because it is designed for the absorption of electrostatic surges.
16.4. Electrostatic test
Electrostatic test should be done on the following conditions.

16.5. Soldering
(1) Flux, Solder
· Rosin-based flux should be used.
Do not use strong acidic flux with halide content exceeding 0.2(wt)% (chlorine conversion value.)
· Use Sn-3.0Ag-0.5Cu solder.
(2) Standard flow soldering profile.
Solder Temperature Soldering Time
250 ~ 260 °C 4 ~ 6 s
(3) Resistance to soldering iron goes in the following condition that tip temperature is 350 °C max. and
soldering time is 5 s max.
(4) Products and the leads should not be subjected to any mechanical stress during soldering process.
(and also while subjected to the equivalent high temperature.)
16.6. Cleaning
Avoid cleaning products.
16.7. Operating Environment
(1) Do not use products in corrosive gased such as chlorine gas, acid or sulfide gas.
(2) Do not use products in the environment where water, oil or organic solvents may adhere to products.
(3) Do not adhere any resin to products, coat nor mold products with any resin (including adhesive) to
prevent mechanical and chemical stress on products.
16.8. Storage condition
(1) Storage period
Products which inspected in MURATA over 12 months ago should be examined and used, which
can be confirmed with inspection No. marked on the container.
(2) Storage environment condition
· Products should be storage in the warehouse on the following conditions.
Temperature : - 10 °C to + 40 °C
Humidity : 15% to 85% relative humidity No rapid change on temperature and humidity
· Don't keep products in corrosive gases such as sulfur, chlorine gas or acid, or it may
cause oxidization of electrode, resulting in poor solderability.
·Products should be stored on the palette for the prevention of the influence from
humidity, dust and so on.
·Products s should be stored in the warehouse without heat shock, vibration, direct
sunlight and so on.
·Products should be stored under the airtight packaged condition.
(3) Delivery
Care should be taken when transporting or handling product to avoid excessive vibration or
mechanical shock.
