!Caution/Notice

o Rating

Do not use products beyond the rated current and rated voltage as this

may create excessive heat and deteriorate the insulation resistance.

o Soldering and Mounting

1. Mounting holes should be designed as specified in these

specifications. Other designs than those shown in these

specifications may cause cracks in ceramics that may

lead to smoking or firing.

2. DSN9/DST9/DSN9H/DST9H/VFS9V Series

Mounting for PCB. (Applis only to bulk type.)

The form of the mounting hole of the bulk item is a triangle.

The product should be inserted and soldered to each hole in

the correct way as in Fig.1. (The center terminal and the other

terminals become parallel when viewing the product from the

side.) Smoking and firing maybe caused by incorrect mounting

as in Fig.2. (The center terminal and the other terminals cross

when viewing the product from the side.)

o Storage and Operating Conditions

o Soldering and Mounting

<Operating Environment>

1. Do not use products in a chemical atmosphere such

as chlorine gas, acid or sulfide gas.

2. Do not use products near water, oil or organic

solvents. Avoid environments where dust or dirt may

adhere to the product.

<Storage and Handling Requirements>

1. Storage Period

Use the products within 12 months after delivery.

Solderability should be checked if this period is

exceeded.

2. Storage Conditions

(1) Storage temperature: -10 to 40 degrees C

Relative humidity: 15 to 85%

Avoid sudden changes in temperature and humidity.

(2) Do not store products in a chemical atmosphere

such as chlorine gas, acid or sulfide gas.

(3) When restoring taping type (BL01RN1A1F1J),

please attach the spacer between the flanges of the

reel. The spacer is corrugated paper that is attached

when shipping.

1. Washing

Failure and degradation of a product are caused

by the washing method. When you wash in conditions

that are not in the mounting information, please contact

Murata engineering.

2. Soldering

Reliability decreases with improper soldering

methods. Please solder by the standard soldering

conditions shown in the mounting information.

3. Other

Noise suppression levels resulting from Murata's

EMI suppression filters EMIFIL

r may vary, depending

on the circuits and ICs used, type of noise, mounting

pattern, lead wire length, mounting location, and other

operating conditions. Be sure to check and confirm in

advance the noise suppression effect of each filter, in

actual circuits, etc. before applying the filter in a

commercial-purpose equipment design.

1. Terminal (with mark) should be properly connected to

the line of incoming electrostatic surge. (There is

polarity.) Otherwise, no effect in ESD suppression can

be expected (VFR3V).

2. Products should be used at rated voltage or less and

rated current or less.

3. Products should not be applied for the absorption of

surges that have large energy (e.g., induced lightning

surges, switching surges) because it is designed for the

absorption of electrostatic surges (VFR3V).

4. Electrostatic testing should be done on the following

conditions (VFR3V).

Notice

3. Take care not to apply any mechanical stress to product

body at the lead terminal bending process for product

angle adjustment after insertion.

For DST9, please do not bend the lead terminal at the

point between the dielectric part and the ferrite bead.
