KTR03

High Voltage Resistance Chip Resistors KTR03 (0603 size : 1 / 10W) Features 1) Power rating of 1 / 10W 2) Limiting element voltage of KTR series is 7 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 ISO9001- / ISO/TS 16949- 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 70°C. 100 80 POWER LOAD (%) Specifications 0.10W (1 / 10W) at 70°C 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= P×R Nominal resistance Operating temperature See Table 1. −55°C to + 155°C P: Rated power (W) R: Nominal resistance (Ω) Limiting element voltage 350V Table 1 Resistance tolerance F (±1%) J (±5%) Resistance range (Ω) 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. www.rohm.com c ○ 2009 ROHM Co., Ltd.
