Center Tap Resistors
Center tap resistors provide two identical resistors in series in a single device, and they are available in all case sizes except 0202. These resistors can be specified with an overall tolerance as tight as 0.1%, and a ratio tolerance as tight as 0.05%. Custom designs can be provided that have two different values on the same chip. Contact the factory for details.

Back Contact Resistors (BCR's)
These resistors use a conductive silicon substrate to make an electrical connection between the top surface and the metallized bottom of the chip. By requiring a single wire bond connection BCR’s allow a more dense circuit design. These devices are available in the 0202 and 0303 case sizes in values 100 ohms and higher with tolerances as tight as 0.5%.

Multi-Tap Resistors
SOTA supplies two varieties of wire bondable multi-tap resistors. These extremely compact .035"X.035" thin film on silicon or alumina (see page 17) resistors supply a wide choice of nominal resistance values by wire bonding to the appropriate pad. Total resistance values are available up to 150 K ohms in 5 or 10% absolute tolerance with TCR’s as tight as 50 ppm. Design MT1 has 7 R1 and 5 R2 resistors where R1 = 5xR2. Design MT2 has 10R1 and 10R2 resistors where R1 = 10xR2. Multi-tap resistors are specified using the total resistance value and adding a -MT1 or -MT2 suffix to the part number.

0609 Ladder Networks
.060"X.090" resistor networks on silicon are available in two schematics. Schematic A has eight isolated resistors of identical value, and Schematic B has eight resistors of identical value with a common ground connection. These devices are available in values from 100 ohms to 500 K ohms in 5 or 10% tolerance with TCR’s as tight as 50 ppm. Ladder networks are specified using the individual resistance value, a 0609 size code, and a -A or -B suffix for the schematic type in the part number.
