RELAYS Panasonic

| Kategorie: Katalog  | Tento dokument chci!

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.

f \ Bad exam ple 2 lic tio n Adjust the position the board so that flux does not overflow onto the top of it. Never use this method. • Unless otherwise specified, solder under the following conditions depending the type relay. Use rosin-based non-corrosive flux. This could impair relay performance. Self-clinching term inal types are available depending on the type relay. 4 g • tic g • Flow solder the optimum method for soldering. • g Keep the tip the soldering iron clean. (Be sure that the relays don't rattle. Note that the board is pressed down hard enough, flux may even penetrate flux-resistant type relay. For dust-cover type relays and flux-resistant type relays, preheating acts prevent the penetration flux into the relay when soldering. inutes • Note that long exposure high tem peratures (e. ith this style, loss function may occur because of seepage into the relay flux, which is applied the board.Excerpts from Technical Information 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. seconds • Please take caution with ulti-layer boards.
