APPLICATION NOTES
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 ±2ppm/°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 ±5ppm/°C.
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
reduced by the width of the tape.
