MVR34 Datasheet | ROHM

.. Resistors Chip Trimmer Potentiometers The MVR34 chip trimmer potentiometer is designed for use in automatic regulators. With its highly stable and reliable ruthenium oxide resistor on an alumina substrate, it offers outstanding dependability in a small, lightweight package. z Features 1) Excellent for use in automatic regulators. 2) Easy to set manually using a regular phillips screwdriver. 3) Superb solder ability thanks to extra soldering electrode. 4) Close match between wiper and dielectric reduces noise. 5) Mounting can be automated by using a carrier tape. 6) Two-digit markings used to indicate resistance. 7) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification. Design and specifications are subject to change without notice. Carefully check the specification sheet before using or ordering it. z Ratings Item Rated power Conditions Power must be derated according to the power derating curve in Figure 1 when ambient temperature exceeds 70°C. 100 80 60 40 20 0 Specifications 0.1W (1 / 10W) / element at 70°C POWER LOAD (%) - 55 AMBIENT TEMPERATURE (°C) Fig.1 Rated voltage The voltage rating is calculated by the following equation. If the value obtained exceeds the maximum operating voltage, the voltage rating is equal to the maximum operating voltage. E: Rated voltage (V) P: Rated power (W) R: Nominal resistance (Ω) Max. operating voltage: 50V E= P×R Nominal total resistance range Total resistance tolerance Resistance variation Effective rotation angle Operating temperature Reactive variable Rotational angle, both ends 100 to 1MΩ (remended resistance value: E3 series) (applicable resistance value: E6 series) ±25% B (linear) characteristics 220±20° - 55°C to +125°C within 10% (R > 150Ω) within 20% (R ≤ 150Ω) - Before using ponents in circuits where they will be exposed to transients such as pulse loads (short-duration, high-level loads), be certain to evaluate the ponent in the mounted state.
