EFFICIENCY VS. TEMPERATURE

These devices are intended for wave soldering or manual soldering.

They are not intended to be subject to surface mount processes

under any circumstances.

The normal wave soldering process can be used with these devices

where the device is subjected to a maximum wave temperature of

260°C for a period of no more than 10 seconds. Within this time and

temperature range, internal temperatures within the converter will not

exceed 175°C. Care should be taken to control manual soldering limits

identical to that of wave soldering.
