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 these products.
REMINDERS
The storage period is less than 6 months. Be sure to follow the storage conditions (Temperature: 5 to 40°C, Humidity: 20 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.
The products listed on this catalog are intended for use in general electronic equipment (AV equipment, telecommunications
equipment, home appliances, amusement equipment, computer equipment, personal equipment, office equipment, measurement

Inductors for Power Circuits
Product compatible with RoHS directive
Halogen-free
Compatible with lead-free solders
AEC-Q200
Thin-film Metal
Overview of TFM201610ALMA Type
FEATURES
By using metal magnetic material with high Saturation magnetic flux density the excellent DC bias characteristics needed for inductors
for power circuits can be achieved.
With the same product shape and terminal structure as general chip parts it has excellent mounting stability characteristics and can also
be mounted to general-purpose land patterns.
By using a closed magnetic circuit structure leakage flux is minimized.
APPLICATION
Equipment used for automobiles (ECM, airbags, headlights, electronic power steering, meters, ABS, other)
