TRR18 Datasheet | ROHM

.. Sulfur Tolerant Chip Resistors TRR18 (3216size (1206inch) ) z Features 1) Unique protect materials prevent from silver sulfide occurrence under sulfur environment. 2) Highly remended for automotive, industrial and Power supply applications under sulfur environment. 3) Realize the good cost performance not like the Au terminal ponents from other suppliers. 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. 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 POWER LOAD (%) Specifications 0.25W (1 / 4W) at 70°C 60 40 20 0 - 55 AMBIENT TEMPERATURE (°C) Fig.1 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= Nominal resistance Operating temperature P×R E: Rated voltage (V) P: Rated power (W) R: Nominal resistance (Ω) Limiting element voltage 200V See Table 1. - 55°C to +155°C Jumper type Resistance Rated current Max. 50mΩ 2A Table 1 Resistance tolerance J (±5%) F (±1%) Resistance range (Ω) 1.0 to 9.1 10 to 10M 10 to 2.2M (E24) (E24) (E24) Resistance temperature coefficient (ppm/°C) ±400 ±200 ±100 Operating temperature - 55°C to +155°C z 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. In addition, the reliability and performance of this ponent cannot be guaranteed if it is used with a steady state voltage that is greater than its rated voltage. .rohm. c 2009 ROHM Co., Ltd.
