MALVERN, PA--(Marketwire - Dec 13, 2012) - Vishay Intertechnology, Inc. (NYSE: VSH) today released the new MPMA series of precision matched-pair resistors. MPMA resistor networks are AEC-Q200-qualified and packaged in a compact molded surface-mount SOT-23.
Each MPMA network is constructed using moisture-resistant thin film tantalum nitride resistor film with enhanced passivation on a high purity alumina substrate. The MPMA device is resistant to moisture at + 85 °C, 85 % relative humidity, and 10 % rated power per MIL-STD-202, method 202.
Offering higher precision matching capability than discrete SMT chips, the AEC-Q200-qualified dividers provide low TCR tracking of 2 ppm/°C and tight ratio tolerance to 0.05 %, with excellent long-term ratio stability over time and temperature.
The MPMA series provides a resistance range from 250 ohms to 50 kilohms with divider ratios from 1:1 to 50:1. With their standard SOT-23 package and wide range of common standard divider ratios, the devices are ideal for precision voltage divider, operational amplifier, and battery signal management applications in automotive, industrial, telecommunications, process control, and medical instrumentation equipment.
Offering a rugged molded case construction, the MPMA networks offer power ratings of 100 mW at + 70 °C per resistor, extremely low noise of less than - 30 dB, low voltage coefficients of less than 0.1 ppm/V, and a operating temperature range of - 55 °C to + 155 °C.
Available with lead (Pb)-free terminations, the resistor networks are RoHS-compliant. Samples of the MPMA series are available now, with lead times of eight to 10 weeks. Follow resistor networks from Vishay at http://twitter.com/vishayindust.
