OnChip Devices 110R: multitapped silicon-chip resistors target use in hybrid electronics
Jun 30 2009 12:00AM | Permalink |Comments (0) |
The 110R series of silicon-chip resistors uses high-stability, self-passivating, and moisture-resistant tantalum-nitride resistor elements, enabling the development of quick-turnaround prototypes in hybrid-microelectronics labs. Comprising a string of 20 resistors, each chip allow wire-bonding for a range of resistances. The strings include a set of 10 2.5-kΩ resistors and a set of 10 25-kΩ resistors, allowing for a 275-kΩ total resistance. Comprising 21 wire-bond pads, the devices provide values of 2.5 to 275 kΩ. Operating over a –55 to +125°C temperature range, the resistors provide a 250-ppm/°C TCR with 10-ppm/°C-maximum-TCR tracking between resistors. Each 110R resistor measures 34×34 mils, and prices range from $3.90 to $7.25, based on tolerance and volume.
