High Power Chip Resistors

LTR18 (3216 size : 1 / 2W)

zFeatures

1) mproved 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.

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

zApplications

Automotive, industrial and power supply.

zRatings

Design and specifications are subject to change without notice.

Carefully check the specification sheet before using or ordering it.

Rated voltage

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.

E: Rated voltage (V)

P: Rated power (W)

E= P×R

zBefore using components in circuits where they will be exposed to transients such as pulse loads (short–duration, high– level

loads), be certain to evaluate the component in the mounted state. In addition, the reliability and performance of this

component cannot be guaranteed if it is used with a steady state voltage that is greater than its rated voltage.
