APPLICATION NOTES
Derating:
The operating case temperature range of the VHB150 series is -40°C to +100°C. When operating the VHB150, proper derating
or cooling is needed. Following is the derating curve of VHB150 without heat sink.

REMOTE ON/OFF CONTROL
The VHB150 series allows the user to switch the module on and off electronically with the remote on/off feature. The VHB150
series is available with “positive logic” or “negative logic” options.
EXTERNAL OUTPUT TRIMMING
Output may optionally be externally trimmed (±10%) with a fixed resistor or an external trimpot as shown.
OUTPUT NOISE
The output noise is measured with a 10μF tantalum capacitor and a 1.0μF ceramic capacitor across the output.
