High Precision Resistor Chip Arrays
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)
•
Pre-tinned terminations over nickel barrier
•
High temperature option (200 °C)
•
SMD wraparound chip resistor array
•
Compliant to RoHS directive 2002/95/EC
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 1 mm,
1.35 mm and 1.82 mm pitch.

Vishay Sfernice
High Precision Resistor Chip Arrays
HIGH TEMPERATURE OPTION: 0031
Vishay Sfernice offers a high temperature option for
applications requiring withstanding to temperature up to
200 °C. Please refer to application note “Power Dissipation -
High Temperature SCH”
www.vishay.com/doc?53047
for
recommendations and mounting considerations.
Operating temperature range: - 55 °C; + 200 °C
Minimum ohmic value: 250
Ω
Absolute TCR: 10 ppm/°C typical (maximum 15 ppm/°C)
TCR tracking: 2 ppm/°C typical (maximum 5 ppm/°C)
Load life stability at 200 °C: < 0.1 % at 0.1 Pn after 1000 h
Tooling charges might be required for custom networks
series (definitive set of masks).

QUICK PROTOTYPING
Vishay Sfernice can offer quick prototyping service in
3 weeks production time for standard and custom networks
(independent resistors - For networks with common point
lead time might be longer). (Logistics time to add to this lead
time). No NRE require for prototyping (small quantity).
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.
PACKAGING
Several types of packaging are available: Waffle-pack and tape and reel.
