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 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.

The products listed on this catalog are intended for use in general electronic equipment (AV equipment, telecommunications

Inductors for Power Circuits

Wound Metallic Magnetic Material

Compatible with lead-free solders

Overview of SPM3020 Type

FEATURES

Magnetic shield type wound inductor for power circuits using a metallic magnetic material.

Low-profile product.

Compared to ferrite wound type inductors, it is possible to achieve large current, low Rdc, and compactness.

Low inductance variance in high-temperature environments with good DC superimposition characteristics.

Metallic magnetic material is used, and the structure has an integrated molded coil, so hum noise is lower than with core adhesive coils.

APPLICATION

Smart phones, tablet terminals, laptop computers, HDDs, servers, VRMs, compact power supply modules, other
