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

• High-stability passivated nichrome resistive

layer 0.02 % on ratio, 1000 h at Pn at +70 °C

• Tight TCR (10 ppm/°C) and TCR tracking

(to 1 ppm/°C)

• Very low noise < -35 dB and voltage coefficient

< 0.01 ppm/V

• Ratio tolerance to 0.01 % (R ≥ 200R)

• High-temperature (230 °C) version, see PRA HT

• ESA-qualified version, see PRA HR

• SMD wraparound chip resistor array

• Thin film technology

• Option to withstand humidity test of AEC-Q200

• Sulfur resistant (per ASTM B809-95 humid vapor test)

• Material categorization: for definitions of compliance

(1) Part number can only have 18 digits. Depending on information needed a compromise has to be found. Consult Vishay

(2) When the last digit(s) of the ohmic value is (are) 0, it (they) must be omitted

E.g.:PRA100I4-2K20BWN → must be ordered under PRA100I4-2K2BWN

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
