■ Characteristics

Note: 1. The above values are initial values.

2. Rated and characteristic (initial) values are for a standard temperature of 23

°C and a humidity of 65% unless otherwise indicated.

3. The contact resistance was measured with 10 mA at 1 VDC with a voltage drop method.

4. The insulation resistance was measured with a 500-VDC megohmmeter applied to the same parts as those used for checking the dielec-

tric strength.

Engineering Data

Note: 1. The tests were conducted at an ambient temperature of 23

°C.

2. The high-frequency characteristics will vary according to the connectors. Be sure to check operation including durability at the actual de-

vice before use.
