| KTR10 Resistors Endured high voltage fixed thick film chip resistor KTR10 (0805 size : 1 / 8W) Features 1) Power rating of 1 / 8W 2) Limiting element voltage of KTR series is 2.6 times compared with that of MCR series. 3) Highly reliable chip resistor Ruthenium oxide dielectric offers superior resistance to the elements. 4) ROHM resistors have approved ISO-9001 certification. Design and specifications are subject to change without notice. Carefully check the specification sheet before using or ordering it. Ratings Item Rated power Conditions Power must be derated according to the power derating curve in Figure 1 when ambient temperature exceeds 70C. 100 80 POWER LOAD (%) Specifications 0.125W (1 / 8W) at 70C 60 40 20 0 -55 0 70 100 155 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: Rated voltage (V) E= PxR P: Rated power (W) R: Nominal resistance () Nominal resistance Operating temperature See Table 1. -55C to + 155C Limiting element voltage 400V Rev.B 1/6 KTR10 Resistors Table 1 Resistance tolerance F (1%) J (5%) Resistance range () Resistance temperature coefficient (ppm/C) 1 R 10M (E24) 1 R 10M (E24) 100 200 Before 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.
