FEATURES
•Isolated, bussed and dual terminator
schematics available
•14, 16 or 20 terminal package
•Molded case construction
•Thick film resistive elements
•Reflow solderable
•Compatible with automatic surface mounting
equipment
•Reduces total assembly costs
•For wave flow soldering contact factory
•Compliant to RoHS directive 2002/95/EC
Notes
• DSCC has created series of drawings to support the need for a surface mount gull wing resistor network product. Vishay Dale is listed as a
resource on this drawing as follows:
These drawings can be viewed at: www.dscc.dla.mil/Programs/milSpec/ListDwgs.asp?DocType=DSCCdwg.
• Power rating depends on the max. temperature at the solder point,the component placement density and the substrate material.
• Jumper: 0 Ω-resistor on request (100 mΩ).
• Packaging: According to EIA; see appropriate catalog or web page.
(1) Temperature range: - 55 °C to + 125 °C.
(2) Continuous working voltage shall be or maximum working voltage, whichever is less.
(3) ± 2 % standard, ± 1 % and ± 5 % available.
Note
(4) Rated voltage: .
* Pb containing terminations are not RoHS compliant, exemptions may apply
