Low Ohmic Compact Thick Film Chip Resistors
UCR10 (2012 size : 1 / 3W)
zFeatures
1) Superior rated power.
2) Stable, low resistance guaranteed regardless of the surrounding environment.
3) Thick film resistive elements were used to create this lineup of ultra-low resistance products ranging from 11m
Ω to 100Ωm.
4) Chip resistors ideal for current detection.
5) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification.

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.

instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers
and other safety devices), please be sure to consult with our sales representative in advance.
It is our top priority to supply products with the utmost quality and reliability. However, there is always a chance
of failure due to unexpected factors. Therefore, please take into account the derating characteristics and allow
for sufficient safety features, such as extra margin, anti-flammability, and fail-safe measures when designing in
order to prevent possible accidents that may result in bodily harm or fire caused by component failure. ROHM
cannot be held responsible for any damages arising from the use of the products under conditions out of the
range of the specifications or due to non-compliance with the NOTES specified in this catalog.
