Coil type EMI Filters

The following are precautions for individual products.Please also refer to the common precautions for Noise Suppression

Device shown on this catalog.

1.Operation range and environments

1 These products are designed and manufactured for general and standard use in general electronic

equipment (e.g. AV equipment, home electric appliances, office equipment, information and communication

equipment)

2 These products are not intended for use in the following special conditions. Before using the products, carefully check

the effects on their quality and performance, and determine whether or not they can be used.

• In liquid, such as water, oil, chemicals, or organic solvent

• In direct sunlight, outdoors, or in dust

• In an environment where these products cause dew condensation

2. Handling

1 Do not bring magnets or magnetized materials close to the product. The influence of their magnetic field can

change the inductance value.

2 Do not apply strong mechanical shocks by either dropping or collision with other parts.

Excessive schock can damage the part.

3. Land pattern design

1 Please refer to the recommended land pattern for each type shown on the datasheet.

2 In case of reflow soldering, consider the layout because taller components close to EMI filters tend to block

thermal conduction.

4. Mounting

1 Avoid excessive placement force.

2 Do not bend or twist the PWB after mounting the part.

5. Cleaning

1 Do not use acid or alkali agents. Some cleaning solvents may damage the part.

Confirm by testing the reliability in advance of mass production.

2 If Ultrasonic cleaning is used, please confirm the reliability in advance.

It is possible that combined resonance of component and PWB and cavitation can cause an abnormal vibration

mode to exist causing damage.
