1. For resistance ratios not shown, contact Vishay’s Applications Engineering Department.
The 300144 can be made available in any required ratio between the resistance values of 100 ohms and 20Kohms, such that R1 can be
any value between 100 ohms and 20Kohms and R2 can also be any value between 100 ohms and 20Kohms. New art work is required.
2. Power is proportional to the divider ratio.
Example: In a 300144 (1K/10K dual), the power rating would be 18 mW on the 1K and 182mW on the 10K, for a total of 200mW on
R1 + R2.

3. Any value from 100 ohms to 20Kohms inclusive is available with some derating of power. (See data sheet “VHD200 and VHD144.”)
4. Maximum working voltage is 200 Volts.
