Resistor networks meet military mandates

Thin film resistor networks are hermetically sealed in nitrogen-filled package cavities, making them immune to outside atmospheric conditions that might cause failures.

BI Technologies Electronic Components Division has developed a series of hermetically sealed thin film resistor networks.

Offered in through-hole DIP and surface-mount packages, the networks meet a number of military qualifications.

"The thin film resistor networks are hermetically sealed in nitrogen-filled package cavities, making them immune to outside atmospheric conditions associated with device failures", says Mike Torres, Fixed Film Product Manager for BI Technologies Electronic Components Division.

"Along with excellent absolute and ratio tolerances, the construction of the networks makes them ideal for military and aerospace applications".

The hermetically sealed networks are approved to MIL-STD-883, MIL-STD-1835, MIL-PRF-38534, MIL-STD-38510 and MIL-STD-202 qualifications.

The thin film resistor networks feature a resistance range from 10ohm to 1Mohm, with absolute tolerances to less than +/-0.05% and ratio tolerance to less than +/-0.01%.

TCRs are less than +/-25ppm/C, with TCR tracking to less than +/-5ppm/C (+/-1ppm/C available).

The networks are available with hot solder dip, tin-lead plate and gold plate finishes.

Typical pricing for the thin film resistor networks is US $35 each in quantities of 50 pieces, with a minimum order quantity of one piece.

Lead time is from 12 to 14 weeks.
