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% 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. 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. 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 in the range 5R0 to 1K0 at 1% tolerance. For low inductance version add suffix N. 5 f1 6 f2 52 Body location f 6 1 - f 2 1.4 mm General Note General Note TT electronics reserves the right to make changes in product specification without notice or liability.
