LTR50_10 Datasheet, PDF (1/4 Pages) Rohm – High Power Chip Resistors

High Power Chip Resistors
<Wide Terminal type>
LTR50 (5025 size : 1W)
 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.
Applications
Automotive, industrial and power supply.
Ratings
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= P×R
E: Rated voltage (V)
P: Rated power (W)
R: Nominal resistance (Ω)
Nominal resistance See Table 1.
