Compact Film Chip Resistors
MCR004 (0402 size : 1 / 32W)
Features
1) Extremely small
Area ratio is 50% smaller than that of chip 0603.
2) High dimensional precision
Novel semiconductor process technology guarantees an external dimensional tolerance of
20µm.
3) Pressed carrier tape applications
Using a pressed carrier tape reduces mounting errors compared with conventional carrier tapes.
4) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification.
Design and specifications are subject to change without notice. Carefully check the specification sheet supplied with the
product 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)
R: Nominal resistance (Ω)
E= P×R

Before
using components in circuits where they will be exposed to transients such as pulse loads (short–duration, high– level
loads), be certain to valuate 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.
