Power Derating Curve
Resistance value, in ohm, is expressed by a series of five characters, four of
which represent significant digits. The fifth R or K is a dual-purpose letter that
designates both the value range (R for ohmic; K for kilo-ohm) and the location
of the decimal point.

Precaution in Using Face-Bonded Chip Resistors
1. Storage
Storage conditions or environment may adversely affect solderability of the exterior
terminals. Do not store in high temperature and humidity. The recommended storage
environment is lower than 40°C, has less than 70% RH humidity and is free from harmful
gases such as sulphur and chlorine.
2. Caution in Soldering
1
Hand Soldering
Hand soldering is applicable as shown at
right.
Recommended
• Temp. of lron Tip: 300°C max
• Power of lron: 20W or less
• Diameter of Tip: dia. 3mm max.
2
Solder Reflow in Furnace
Recommended
• Peak Temperature: 245°C
• Holding time: 220°C (40sec.max.)
• To cool gradually at room temperature
3
Dipping in Solder (Wave or Still)
Recommended
• Temp. of Solder: 240°C to 250°C
• Length of Dipping: 3 to 4 seconds
• To cool gradually at room temperature
4
Other
Corrosion-free flux, such as rosin, is recommended.
Do not apply pressure to the molded housing immediately after soldering.

3. Cleaning
Use volatile cleaner such as methylalcohol or propylalcohol.
4. Circuit Board Design
The dimensions of solder land must be determined in conformity with the size of resistors
and with the soldering method. They are also subject to the mounting machine and the
material of the substrate. See example below.

Dimensions in mm
When parts are mounted on a board in high density, solder can possibly attach to the
resistors in an excessive amount to affect performance or reliability of the resistors. To
prevent this effect, the use of solder resist is recommended to isolate solder lands.
