FEATURES ç¹é·
ï· TOKOâs LLM2520/LLM3225 is a wire-wound small chip
inductor most suitable for surface mount. It is
recommended for various general use for signal
conditioning in a variety of electronic equipment.
ï· TOKOâs LLB2520 is a small size chip inductor of the
surface mounted type with a wire-wound structure
characterized by a low DC resistance. It is the most
suitable for the decoupling inductor for a small current.
ï· Possible for Refelow Soldering.
ï· High-reliability component due to the monolithic construction.
ï· RoHS compliant.

PRECAUTIONS ã使ç¨ä¸ã®æ³¨æ
1. Precaution for application
1.1 The part must be pre-heated before soldering if reflow is
applied.
The difference between pre-heat temperature and
soldering temperature must be within 150°C.
1.2 If a soldering iron is applied, the soldering process must
be completed within 4 seconds at the soldering
temperature lower than 350°C.
The tip of the soldering iron must not touch the terminal
electrode in this process.
1.3 Soldering by using soldering iron must be only once for
the same part.
1.4 PCB mounted this part must be handled with a care to
minimize any physical stress to the part at the board
assembly process.
1.5 To minimize the influence to the part, the thickness of
PCB, land dimension, and the amount of solder must be
evaluated carefully by individual application.
1.6 HCFC and isopropil alcohl used for the washing
process will not affect the part perfomance.
2. Precaution of storage
Storage condition is critical to maintain an optimum
soldering performance.
2.1 Environmental requirements:
Control ambient temperature at or under 40°C and
70%RH.
Recommended use of the products within 6 months.
2.2 Influence of harmful gas:
Store the products in a place isolated from harmful gases
like sulfur and chlorine.
