Cover story
These risks are exacerbated by the fact that most industrial communications semiconductors need to: • Perform over a wider temperature range; • Be guaranteed to be secure from intrusion (malware susceptibility of non- authorised components);
• Perform in a harsh external environment of electrical noise, vibration and contamination; and, so, they command an additional price premium – thus attracting even more unwelcome attention from the counterfeiters. Authorised after-market distributors and manufacturers, such as Rochester Electronics, provide a risk-free long-term source for the key semiconductors for industrial communications networks. Rochester is an authorised partner supporting: • Available stock to overcome market shortages or long lead-times; • A trusted source for obsolete parts off-the-shelf; • Long-term manufacturing from wafer of selected semiconductor product ranges.
Rochester’s product portfolio includes: Analog and mixed signal: power management – regulators, MOSFET and IGBT gate drivers, data converters, signal conditioners, receivers, sensors, power converters and modules, LED-backlight and peripherals, amplifiers and multiplexer/switches and a lot more.
