Packaging RC55 and RC65 standard packing is in tape, as shown below, whilst RC70 is bulk packed. Taped resistors on reel or loose packed components can also be supplied by special request. 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. 5 The individual resistors within a set or module can be manufactured with a tolerance of 0.05% and TCR of 5ppm/C. f1 6 A low inductance version is available in the range 5R0 to 1K0 at 1% tolerance.
