## **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: 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.

## **Common Mode Filters**
**Product compatible with RoHS directive Compatible with lead-free solders**
## **For high-speed differential signal line, general signal line**
## **Overview of ACM2520 Type**
## **FEATURES**
Downsized wound type chip common mode filter that maintains required common mode filter characteristics. Impedance for common mode noise can clear 1000 [100MHz], and has excellent EMC suppression.
Differential mode impedance is suppressed, so there is virtually no affect on high speed signals. There is a two-line type and a three-line type, so they can be used for various circuits and noise.
## **APPLICATION**
Common mode noise countermeasure for high-speed differential signals where influence to the signal is a concern. USB line for PCs and peripheral devices.
IEEE1394 lines and ETHERNET lines for PCs, STBs, etc.
LCD panel LVDS and Panel Link lines.
