5 Safety recautions 1. Rated ower and Ambient Temperature Keep te rated power and ambient temperature witin te specified derating curve. ] Mount resistors and oter eating components on te board, taking into consideration te cumulative temperature rise of all components. 2. External Sock Mecanical sock during automatic mounting or andling of board after cip is mounted may result in breakage, or separation of protective coating of te resistor wic may impair initial caracteristics. 3. Ultrasonic Cleaning Ultrasonic cleaning may sever lead wire due to resonance. Verify before actual use. 4. Application of ulse Wen pulse is applied to a resistor, te peak value of te pulse sould be witin rated voltage. [Flame-retardant roduct] 5. External Sock Flame-retardant resistors are more susceptible to external sock and solvent tan regular resistors. Handle wit care 6. Solvent External coating for flame-retardant resistors is not resistant to solvent. ay attention to use of solvent. If solvent is used for cleaning, please mount tese resistors after te cleaning procedure. Before ordering, test sample components in your application to ensure proper function and compatibility.
