Construction
Marking
Type reference, TCR code, resistance value and
tolerance code.
A metal film is deposited onto a high quality ceramic
former. Nickel-plated steel caps are force fitted to the
former and termination wires are welded to the caps.
The resistance values conform to IEC 62.
The resistor is adjusted to value by a helical cut in the film
and the body is protected with a specially formulated epoxy
coating.
Solvent Resistance
Terminations
The body protection and marking are resistant
to all normal industrial cleaning solvents
suitable for printed circuits.
Material
100% tin plated over copper wire
Strength
The teminations meet the requirements of
IEC 68.2.21.
Solderability The terminations meet the requirements
of IEC 115-1, Clause 4.17.3.2.

Application Notes
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.
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.
