5 pcs guildline model 9330 resistance standards made in Canada

1 pc. Of each-100 ohm, 1k, 10k, 100k, 1 Megohm. All 5 pcs for 1 money. Free shipping in conus. Guildline series 9330 standard resistors contain hermetically sealed resistance elements. The resistance wire element is suspended in oil in a hermetically sealed case with a cover plate of low leakage acrylic. All terminals are solid thermal copper to reduce thermal EMF's FEATURES: Nominal Resistance; 10 kohms Stability +/- 2.5 ppm (6 months), +/- 3.5 ppm (12 months) Nominal Initial Tolerance: 2.5 ppm 4 Terminal Design Temperature Coefficient: < 2.5 ppm deg. C Maximum Current: 3.2 mA Maximum Voltage: 32 V Nominal initial tolerance is the maximum variation of resistance mean value as adjusted initially at the factory.
