1 / 6 page KTR18 Resistors Rev.B 1/5 Endured high voltage fixed thick film chip resistors KTR18 (1206 size: 1 / 4W) Features 1) Power rating of 1 / 4W 2) Limiting element voltage of KTR series is 2.5 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 0.25W (1 / 4W) −55 °C to +155°C 500V at 70 °C Item Conditions Specifications Rated power Rated voltage Operating temperature Nominal resistance See Table 1. Limiting element voltage Power must be derated according to the power derating curve in Figure 1 when ambient temperature exceeds 70 °C. 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 0 20 40 60 80 100 −55 0 70 100 155 AMBIENT TEMPERAT URE ( °C) Fig.1 Table 1 Resistance tolerance Resistance range ( Ω) Resistance temperature coefficient (ppm / °C) F ( ±1%) J ( ±5%) 1 ≤ R ≤ 10M 1 ≤ R ≤ 10M (E24) (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. |
