TCR
Type
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.

1. Storage
Storage conditions or environment may adversely affect solderability of 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 Solder Reflow in Furnace
Recommended
• Peak Temperature: 245°C
• Holding time: 220°C (40sec.max.)
• To cool gradually at room temperature
2 Dipping in Solder (Wave or Still)
Recommended
• Solder Temperature: 240°C to 250°C
• Length of Dipping: 3 to 4 seconds
3 Other
Corrosion-free flux such as rosin is recommended.
3. Cleaning
Use volatile cleaner such as methylalcohol or propylalcohol.
