| The ECG cross reference signifies an ECG | | | | Silicon asymmetrical switches (SAS), and |
| replacement directory, which lists more than | | | | bilateral trigger diodes (DIACS). Soon, |
| 300,000 manufacturer house numbers, and these | | | | semiconductor devices such as JFETS, MOSFETS, |
| numbers are cross referenced to ECG types | | | | and IGBT were added. Multipliers, rectifiers |
| that can replace them. The directory, which | | | | and other such high voltage devices also |
| started with a list of semiconductors, soon | | | | found themselves in the list. Transient |
| included other products as well.The ECG line | | | | voltage suppressors, quartz crystals, linear |
| of semiconductors was originally | | | | and digital integrated circuits and |
| conceptualized by Sylvania before Philips | | | | optodevices have now been added to the ECG |
| took over the company, and though these | | | | series. With advancement of information |
| semiconductors were originally targeted at | | | | technology and increased use of computers and |
| the secondary markets, they soon found their | | | | related accessories, the ECG line has |
| way into the industrial repair and | | | | microprocessors, memories, IC interfaces and |
| maintenance departments. The ECG cross | | | | even surface mounted components. The ECG |
| reference is a great help in looking up U.S. | | | | product line now includes |
| and foreign manufacturer numbers and thereby | | | | environment-friendly chemicals, digital |
| identifying the device type, printout and | | | | multi-meters, surge protectors, flyback |
| other relevant information. The greatest | | | | transformers, flameproof resistors, antenna |
| advantage of the ECG cross reference is the | | | | rotators and rechargeable batteries.The NTE |
| amount of time saved without searching | | | | Electronic Inc. has now taken over ECG from |
| through catalogues or hunting for | | | | Philips and the ECG series numbers now |
| manufacturers.The ECG cross reference | | | | coincide with NTE numbers, and both are made |
| constitutes a long list that is quite | | | | available.ECG provides detailed information |
| comprehensive. This includes transistors, | | | | on ECG, ECG Course, ECG Cross Reference, ECG |
| diodes, and ICs, silicon bilateral switches | | | | Semiconductors and more. ECG is affiliated |
| (SBS), Silicon unilateral switches (SUS), | | | | with EKG Interpretation. |
