PRAHT arrays can be used in most applications requiring a
matched pair (or set) of resistor elements at very high
temperature up to 230 °C. The networks provide 2 ppm/°C
TCR tracking, a ratio tolerance as tight as 0.05 % and
outstanding stability. They are available in 1 mm, 1.35 mm,
and 1.82 mm pitch.

PACKAGING RULES
Waffle Pack
Can be filled up to maximum quantity indicated in the table
here above, taking into account the minimum order quantity.
When quantity ordered exceeds maximum quantity of a
single waffle pack, the waffle packs are stacked up on the
top of each other and closed by one single cover.
To get “not stacked up” waffle pack in case of ordered
quantity > maximum number of pieces per package:
Please consult Vishay Sfernice for specific ordering
code.
Tape and Reel
Can be filled up to maximum quantity indicated in the table
here above, taking into account the minimum order quantity.
When quantity ordered is between the MOQ and the
maximum reel capacity, only one reel is provided.
When several reels are needed for ordered quantity
within MOQ and maximum reel capacity: Please consult
Vishay Sfernice for specific ordering code.
