Vishay has released the MP series of precision thin film resistor divider networks, claimed to be the first devices to offer 0.05% resistance ratio tolerance in the ultra-small SC-70 package.
Intended for use in instrumentation amplifiers, precision voltage dividers, and bridge network circuitry, the surface mount devices in the Thin Film MP series are optimised for industrial control systems, handheld instruments and other end systems requiring precision resistor pairs with small dimensions.
These off-the-shelf devices provide tolerances down to 0.05%.
The devices are available as isolated matched-pair or centre-tapped resistor divider networks in 3-lead (MP3) or 4-lead (MP4) standard moulded SC-70 packages with maximum dimensions of 2.200 x 1.350 mm.
The new networks feature low TCR (temperature coefficient ratio) tracking of ±2 ppm/°C, and their standard SC-70 package format provides common standard resistance values ranging from 1 to 10 kohm per resistor.
Each network is specified for a TCR value of ±25 ppm/°C and a power rating of 0.075 W per resistor or 0.150 W for the package.
