Okaya Surge Absorbers

RA Series


Description

The RA-V6-2 series utilizes creeping corona discharge, thus demonstrating extremely fast response characteristics in dark ambient conditions without the use of radioactive isotopes. For example, a 1.2/50µs, 10kV surge voltage can be suppressed to about 1 kV.

Applied as indirect lightning surge protection in telephone equipment, this model is used for parallel connection between T and R in telephone receivers. Also, by connecting this absorber within electronic circuits, network computers can be protected from destructive impulse current.

Features:

bulletFast response time.
bulletThis Surge Absorber is bipolar. The device will fail open if the surge withstand capability is exceeded.
bulletInter-terminal capacity is extremely small, resulting in little influence on electronic circuits.
bulletHigh insulation resistance (1X109 ohms or more).
bulletRepeatable: may be used up to 300 times at 500A (8/2Oµs).
bulletSmall size allows soldering together with resistors or other electronics components.
bulletProduct available taped for auto insertion. Add "Y" to model number (RA-201 P-V6Y-2).
