10. Notice
This product is designed for solder mounting.
Please consult us in advance for applying other mounting method such as conductive adhesive.
10-1. Land pattern designing
Standard land dimensions (Flow and Reflow soldering)
(in mm)
*The excessive heat by land pads may cause
deterioration at joint of products with substrate.
Land dimensions on Flow soldering for 2.5mm pitch mounting
*Taking land pad thickness and rated current into
account.

2.0 4.2 to 5.2 1.2 1.3 1.35
(in mm)
*The pattern shall be designed to above drawing to
prevent causing the solder bridge when products
are mounted by 2.5mm pitch flow soldering.
10-2. Soldering Conditions
Products can be applied to reflow and flow soldering.
(1) Flux,Solder
Flux Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. )
Do not use water-soluble flux.
Solder Use Sn-3.0Ag-0.5Cu solder
Standard thickness of solder paste : 100 µm to 200 m
(2) Soldering conditions
Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is limited
to 150℃ max. Also cooling into solvent after soldering should be in such a way that the temperature difference
is limited to 100℃ max.
Insufficient pre-heating may cause cracks on the ferrite, resulting in the deterioration of product quality.
Standard soldering profile and the limit soldering profile is as follows.
The excessive limit soldering conditions may cause leaching of the electrode and / or resulting in the
deterioration of product quality.
