MATCHED SETS AND NETWORKS
IRC has many years of experience in the supply of matched
sets of precision resistors.
Refer to application notes for more details
ENQUIRIES WELCOME
APPLICATION NOTES
Resistors can be supplied matched for tolerance and TCR down to ±0.005% and ±1pmm/°C, either as separate resistors or pre-
assembled and encapsulated within a plastic box.
The individual resistors within a set or module can be manufactured with a tolerance of ±0.01% and a TCR of ±5ppm/°C.
PACKAGING
The standard packaging is loose in boxes. Taped resistors
(on reel or in ammo pack) can also be supplied by special
request. In case the usable length is reduced by the width of
the tape. A detail taping specification is available on request.
ORDERING PROCEDURE
Specify type reference etc. as indicated in this example of
CARS 6.8K ohms 0.1% 50ppm/°C.
