Reference: A maximum current of 0.15 A can be switched at 125 VDC (cosφ = 1).
Note: 1. The H3CA Series has been tested for the following: impulse voltages, noise
2. Minimum applicable load (P reference values):
H3CA-A(FA), H3CA-8H: 100 mA at 5 VDC
H3CA-8: 10 mA at 5 VDC
(via noise simulator, for L loads, and for relay oscillation), and resistance to
static electricity.
Maximum current of 0.1 A can be switched if L/R is 7 ms. In both cases, a
life of 100,000 operations can be expected.
