Thin film resistor networks enable higher precision
A series of surface mount dual-in-line thin film resistor networks, featuring improved performance and a smaller size than previous generation SOIC devices, has been launched by Vishay International.
Offering a slim maximum seated height of 1.10mm, the Vishay Dale Thin Film MORN series delivers lower TCR tracking to ±1ppm/°C, tighter ratio tolerances to ±0.01%, and long term ratio stability of 0.015% after 2,000 hours at 70°C.
MORN series devices feature four isolated resistors with resistance values from 400Ω to 100kΩ. Offered in compact 25 mil pitch, 8-pin MSOP packages - in accordance with JEDEC MO-187, variation AA - the resistor networks provide a moulded construction and typical power ratings of 50mW per resistor element.
The integrated construction of MORN resistor networks allows for higher precision over discrete SMD chips, making the devices well suited for precision voltage dividers and unity gain operational amplifier circuitry. Typical end products will include telecommunications, industrial, process control and medical instrumentation.
The devices feature low noise of equal to or less than -30dB and voltage coefficients of 0.1ppm/V. They operate over a temperature range of -55 to 125°C. MORN series devices are RoHS compliant and halogen-free.
Samples and production quantities of the new resistor networks are available now, with lead times of eight to ten weeks for larger orders.
