High Power Chip Resistors<Wide Terminal type>

LTR18 (3216 size : 1 / 2W

)

Features

1)

Improved welding strength

The structure of longer electrodes provides the wider welding area than the chip resistors with normal electrodes,

and this enhanced the solder welding strength.

2)

Increased surge-resistance

This is achieved by Rohm’s original trimming technology plus resistive element patterning.

3)

High-power tolerance

Two times of the rated power is guaranteed than the normal-electrode resistors.

4)

ROHM resistors are ISO-9001 & ISO/TS16949 certified.

Design and specifications are subject to change without notice. Carefully check the specification sheet before using

or ordering it.

Applications

Automotive, industrial and power supply.

The voltage rating is calculated by the following equation.

If the value obtained exceeds the limiting element voltage,

the voltage rating is equal to the maximum operating voltage.
