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.
Use rosin-based non-corrosive flux. Note that the board is
pressed down hard enough, flux may
even penetrate flux-resistant type
relay. Relay performance may

If the board pressed down into a
flux-soaked sponge shown the
right, the flux can easily penetrate a
dust-cover type relay. Solderability also improves. Please
review the parts construction and
characteristics. For dust-cover
type relays and flux-resistant type
relays, preheating acts prevent the
penetration flux into the relay when
soldering. Never use this
method. Therefore, the

RELAY SOLDERING AND CLEANING GUIDELINES
In keeping with making devices compact,
it becoming more common weld the
relay board along with the
sem iconductors instead using the
previous plug-in type which relays
were plugged into sockets.
