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.
A low inductance version is available at 1% tolerance.
For low inductance version add suffix N.
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.
