LTR10_1 Datasheet, PDF (1/4 Pages) Rohm – High Power Low Ohmic Chip Resistors

High Power Low Ohmic Chip Resistors<Wide Terminal type>
LTR10 (2012 size : 1 / 2W)
zFeatures
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.

The voltage rating is calculated by the following equation.
E= P×R
I = P/R
E : Rated voltage (V)
I : Rated current (A)
P : Rated power (W)
R : Nominal resistance (Ω)

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.
