This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc. The output waveforms can be both amplitude and frequency modulated.

However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities.

In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature Tstg max.

If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Repairing soldered joints Apply a low voltage soldering iron less than 24 V to the lead s of the package, below the seating plane or not more than 2 mm above it. This data sheet contains preliminary data; supplementary data may be published later.

This data sheet contains? Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the speci? Exposure to limiting values for extended periods may affect device reliability.

Application information Where application information is given, it is advisory and does not form part of the speci? Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale.
