Fullerton, Calif. TT electronics 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 resistor networks meet a number of military qualifications.
Hermetically sealed in nitrogen-filled package cavities, the thin-film resistors are immune to outside atmospheric conditions associated with device failures, said BI Technologies. They 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 10 ohms (Ω) to 1 MΩ, with absolute tolerances to less than ±0.05% and ratio tolerance to less than ±0.01%. Temperature coefficient of resistance (TCR) values are less than ±25 ppm/°C, with TCR tracking to less than ±5 ppm/°C (±1 ppm/°C available). The networks are available with hot solder dip, tin-lead plate and gold-plate finishes.
Pricing: Typically priced at $35 each in quantities of 50 pieces, with a minimum order quantity of one piece.
Availability: Lead time is from 12 to 14 weeks.
