REMINDERS FOR USING THESE PRODUCTS
Before using these products, be sure to request the delivery specifications.
SAFETY REMINDERS
Please pay sufficient attention to the warnings for safe designing when using this products.
The storage period is less than 12 months. Be sure to follow the storage conditions (temperature: 5 to 40°C, humidity: 10 to 75% RH or
less).
If the storage period elapses, the soldering of the terminal electrodes may deteriorate.
Do not use or store in locations where there are conditions such as gas corrosion (salt, acid, alkali, etc.).
Before soldering, be sure to preheat components.
The preheating temperature should be set so that the temperature difference between the solder temperature and chip temperature
does not exceed 150°C.
Soldering corrections after mounting should be within the range of the conditions determined in the specifications.
If overheated, a short circuit, performance deterioration, or lifespan shortening may occur.
When embedding a printed circuit board where a chip is mounted to a set, be sure that residual stress is not given to the chip due to
the overall distortion of the printed circuit board and partial distortion such as at screw tightening portions.
Self heating (temperature increase) occurs when the power is turned ON, so the tolerance should be sufficient for the set thermal
design.
Carefully lay out the coil for the circuit board design of the non-magnetic shield type.
A malfunction may occur due to magnetic interference.
Use a wrist band to discharge static electricity in your body through the grounding wire.
Do not expose the products to magnets or magnetic fields.
Do not use for a purpose outside of the contents regulated in the delivery specifications.

EMC Components
Noise suppression filter
For audio lines (Class D amplifier noise suppression)
FEATURES
A compact noise suppression component for audio lines that accommodates high currents.
Distortions are greatly reduced during insertion with the adoption of newly-developed low distortion ferrite materials.
Small reductions in volume due to its low resistance, and optimal for devices that require high sound quality as the generating of sound
distortions is controlled.
High efficacy is put for high frequency noise suppression of class D amplifier harmonics in 100 to 400MHz because of high damping
property.
APPLICATION
Sound lines for devices such as smartphones and tablets (earphones, microphones, and speakers).
Sound lines for portable game machines.
