For flat chip jumper resistor, please refer to RK73Z series.
※5 The nominal resistance value for RK73H1F（10Ω≦R≦2MΩ）and RK73H1H（1Ω≦R≦9.1Ω, 1MΩ≦R≦10MΩ）is E24.
※6 If you use at the rated power, please keep the condition that the terminal of the resistor is below the rated terminal part temperature. Please refer to the derating curves based on the terminal temperature of right side on the next page.
※7 Standard packaging：TD(4mm pitch punch paper)
※8 Standard taping specification of 1H is TCM. Previously available“TC(10,000pcs/Reel)”is not recommended for new designs.
If any questions arise whether to use the“Rated Ambient Temperature”or the“Rated Terminal Part Temperature”in your usage conditions, please give priority to the“Rated Terminal Part Temperature”.
For more details, please refer to“Introduction of the derating curves based on the terminal part temperature”on the beginning of our catalog.
While using under high power, the temperature of the product may increase depending on the condition of heat dissipation from PCB.
Be sure to check the terminal part temperature as well as precautions to use on delivery specifications before use.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
