Application Notes

Matched Sets and Networks

TT electronics 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.

For low inductance

version add suffix N.

A low inductance version is available in the range

5R0 to 1K0 at 1% tolerance.

Packaging

RC55 and RC65 standard packing is in tape, as shown below,

whilst RC70 is bulk packed. Taped resistors on reel or loose

components can also be supplied by special request.

Note1:

1. Based on sampling. 100% screened product is available.

2. For maximum availability, where the ohmic value permits, 25ppm/˚C is preferred to 50 or 100ppm/˚C.

3. For maximum availability, where the ohmic value permits, 0.25% is preferred to 0.5% or 1%
