Application product(RS422 Port....etc ):
A friendly reminder: Any surface mount component and DIP component can alternative use,
( For example: H3R5-90SMD= H3R6-90 , JK250120U = JK-mSMD014 , P6KE6.8CA = SMBJ6.0CA)
(So You can also use: H3R6-90 + JK250120U + SMBJ6.0CA, H3R5-90SMD+ JK250120U+ P6KE6.8CA ...ETC)
Statement: These solution is only for reference, The final solution will be based on the actual test results, HUAAN LIMITED will have
the right of final explanation.
