Low Ohmic Compact Thick Film Chip Resistors
UCR18 (3216(1206) size : 1 / 2W)
zFeatures
1) Chip resistors ideal for current detection. (11mΩ to 100mΩ)
2) Unique chip and terminal configuration reduces resistance shifting during the mounting process.
3) Superior rated power.
4) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification
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.
E= P×R
E: Rated voltage (V)
P: Rated power (W)
R: Nominal resistance (Ω)
Nominal resistance See Table 1.

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.
