11.12 Storage and Handing Requirements
(1) Storage period
Use the products within 12 months after delivered.
Solderability should be checked if this period is exceeded.
(2) Storage conditions
Products should be stored 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 not be stored on bulk packaging condition to prevent the chipping of the
core and the breaking of winding wire caused by the collision between the products.
Products should be stored on the palette for the prevention of the influence from humidity,
dust and so on.
Products should be stored in the warehouse without heat shock, vibration, direct sunlight and
so on.
(3) Handling Condition
Care should be taken when transporting or handling product to avoid excessive vibration or
mechanical shock.

(3) Thus,the relation between Zx and Zm is following;
Zx= α
Zm-β where, α= D / A =1

Γ= C / A =Yom
Zsm : measured impedance of short chip
Zssa: residual impedance of short chip (0.556nH)
Yom: measured admittance when opening the fixture
