Frequently Asked Questions
What types of electronics applications are TLP couplers suitable for?
They are suitable for on-board power supplies, programmable controllers, and general electronic devices like computers or office equipment.
What is the minimum required isolation voltage rating?
The specified isolation voltage must be 2500 Vrms at a maximum of one minute.
How should these products be disposed of after use?
Follow appropriate regulations; do not dispose of them with other industrial waste or domestic garbage due to GaAs contents.
Can the TLP couplers be used in highly reliable or critical systems?
No. They are intended for general electronics and should not be used in equipment requiring extraordinarily high quality, such as medical instruments or airplane devices.
