Matched Sets and Networks
Welwyn has many years experience in the supply of
matched set of precision resistors
Resistors can be supplied matched for tolerance
and TCR down to ±0.02% and ±2 ppm/°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 ±0.05% and TCR of
±5 ppm/°C.
A low inductance version is available at 1% tolerance.
For low inductive version add suffix N.
Resistance Value
Ex: 6K8 = 6.8KΩ
Tolerance
F = ±1%, D = ±0.5%, C = ±0.25%, B = ± 0.1%, W = ±0.05%
Packaging
A = Ammo Pack; B = Bulk; T = Tape and Reel

Packaging
The standard method of packaging RC55 resistors
is taped in ammo packs. Taped resistors on reel or
loose packed components can also be supplied by
special request. The standard packaging for RC65
and RC70 resistors is loose in boxes. By special
request the RC65 components can also be supplied
taped on reel or in ammo pack. In the case of tape
packed components the usable lead length is re-
duced by the width of the tape.
