Marking

Construction

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

The body protection and marking are resistant to all normal

industrial cleaning solvents suitable for printed circuits.

Terminations

Material

Solder coated copper wire

Strength

The terminations meet the requirements of

IEC 68.2.21.

Solderability

The terminations meet the requirements of

IEC 115-1, Clause 4.17.3.2.

Packaging

Application Notes

The standard method of packaging RCꢂꢂ 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 RC6ꢂ and RC7± resistors is loose in

boxes. By special request the RC6ꢂ 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.

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 ±±.±02 and ±0ppmꢀ/Cꢁ 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 ±±.±ꢂ2 and TCR of

±ꢂppmꢀ/C.

A low inductance version is available at 12 tolerance.

For low inductance version add suffix N.
