Panasonic is part of a large worldwide groupselling relays and associated switching products under different brand names in different territories.The conditions of use in some territories may differ from those customary in Europe. In particular there are often major differences in regard to national and international specifications, such as UL, CSA, VDE, SEV, EVE, SEMKO, etc. Thus, when considering contact loads as stated in this catalogue (e.g. 10 A, 30 VDC for the SP relay) its hould be understood that these values are not necessarily an absolute maximum but tested ratings. Mostly the stated value has been tested for a certain life expectancy as stated by the manufacturer or the respective test house. Thus, under different conditions, the stated “maximum” may, in practice, be safely exceeded.

• Adjust the position the board so
that flux does not overflow onto the top
of it. For dust-cover
type relays and flux-resistant type
relays, preheating acts prevent the
penetration flux into the relay when
soldering. Solderability also improves. Self-clinching
term inal types are available depending
on the type relay. This must observed especially
for dust-cover type relays. Never use this
method.g.

not overflow onto the top the PC

• Use rosin-based non-corrosive flux.

don't rattle. Note that the board is
