The LL-1443-20B filter has been developed for use with
automotive electrical systems . Automotive electrical
systems are very noisy and electronic systems installed
in vehicles need to be protected against the electrical
interference and transients generated by the power sys-
tem. This filter is designed to provide this protection.
The difference between this (-20B) filter and the (-20) is
that this (-20B) has a (OUT -) terminal.
Operating voltage (max) = 50 Vdc
Operating Current (max) = 20 Amperes
Temperature range (storage) = -40 to 105 C
Temperature range (operating) = -40 TO 65 C
