Cautions for Safety

1. Component Placement

A Take measure against mechanical stress during and after mounting so as not to damage the termination

and protective coating.

B Misplacement of components on the land pattern may cause solder bridge problem.

3. Cleaning

Recommendable cleaning method is shown below.

Solvents

Cleaning condition

Dipping

Ultrasonic wave washing

Isopropyl

Alcohol

4.

If transient load (heavy load in a short time) like pulse is expected to be applied, carry out evaluation and

confirmation test with the resistors actually mounted on your own board.

When the load of more than rated power is applied under the load condition at steady state, it may impair

performance and/or reliability of resistor. Never exceed the rated power.

5.

Chlorine type or other high-activity flux is not recommeded as the residue may affect performance or reliability

of resistors.

6.

When soldering with soldering iron, never touch the body of the chip resistor with a tip of the soldering iron.

When using a soldering iron with a tip at high temperature, solder for a time as short as possible (three

seconds or less up to 350 ¡C).

7.

Avoid physical shock to the resistor and nipping of the resistor with hard tool (a pair of pliers or tweezers) as

it may damage protective film or the body of resistor and may affect resistorÕs performance.

8.

Do not use the product in dewy atmospheres.

2. Soldering

Precaution and recommondations are described

below.

(a)Soldering iron

Keep the followings:

A Soldering iron tip shall not touch the protective

coating of the part.

B Solder as quick as possible (within 3 seconds)

when the temperature of the soldering iron tip is

over 280 ¡C.

(b)Reflow soldering

Recommendable reflow soldering is shown right.
