High-Precision Thin Film Chip Resistor Arrays, Sulfur Resistant
DESIGN SUPPORT TOOLS AVAILABLE
PRA arrays can be used in most applications requiring a
matched pair (or set) of resistor elements. The networks
provide 1 ppm/°C TCR tracking, a ratio tolerance as tight as
0.01 %, and outstanding stability.
They are available in pitch:
0.70 mm for PRA073 (based on case 0302)
0.70 mm for PRA074 (based on case 0402)
1.00 mm for PRA100 (based on case 0603)
1.35 mm for PRA135 (based on case 0805)
1.82 mm for PRA182 (based on case 1206)
FEATURES

SPECIAL FEATURES
Resistance values can be different on a given network
(R max./R min. as high as 300). Tooling charges might
be required depending on the ohmic values in the
same network. Please, consult Vishay Sfernice for ohmic
values, tolerances and also temperature coefficient (e.g.
± 1 ppm/°C) outside the standard range.
AEC-Q200 OPTION: 0058
Vishay Sfernice offers a part compliant to AEC-Q200
specification.

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.
POWER RATING
MARKING (1)
On the primary package, printed information includes
Vishay S.A. trademark series and model, schematic number
of resistors, ohmic value, absolute tolerance, ratio tolerance,
type of termination: B tinned over nickel barrier.
Marking on parts:
All resistors inside network have same ohmic value:
If number of resistors inside network < or = 3
For instance ohmic value 13K:
Coded 1302: M = 1, C = 3, D = 0, U = 2
If number of resistors inside networks > 3
E.g.: 4 resistors in the network:
Ohmic value 13K: Coded 1302: M = 1, C = 3, D = 0, U = 2
Resistors inside the network have different ohmic value, a
CNW number is assigned by Vishay Sfernice
If number of resistors inside network < or = 3
E.g.: CNW1538: M = 1, C = 5, D = 3, U = 8
If number of resistors inside networks > 3
E.g.: 4 resistors in the network:
E.g.: CNW1314: M = 1, C = 3, D = 1, U = 4
Note
(1) PRA073 and PRA074 are NOT marked. For CNW of size 073 and 074, only a “dot” is marked to identify R1
