Example of Applications
An Application of Type MU (input/feedback resistors for amplifiers)
Because the input and the feedback resistors are incorporated into one single element,
amplification is not affected by temperature change.

Precaution in Using Face-Bonded Chip Resistor
1. Storage
Storage condition 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 free is 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.
When parts are mounted on a board in high density, solder can possibly attach to the
resistors in an excessive amount to affect peformance or reliability of the resistors. To
prevent this effect, the use of solder resist is recommended to isolate solder lands.
