Available in resistances of 1, 10, 25, 100Ω (SRA values) and 1,000 and 10,000Ω (SRB values), the Isotech Model 836 miniature fixed resistors feature an accuracy adjustment of ±20ppm and a 2ppm per year stability. The element of the Isotech miniature fixed resistors is strain free and immersed in dry oil, while the top panel is constructed of Bakelite with PTFE inserts and engraved lettering. One more important feature of the Isotech fixed resistors is that the AC/DC characteristics are the same up to approximately 1,000 Hz.
Resistance thermometry refers back to one or more fixed resistors. Resistors need to be very stable with time, temperature and transportation, as well as have negligible inductance and capacitance. The Isotech Model 836 miniature fixed resistors feature a design flexible enough to allow windings with various resistance values to be made available and stable enough to be accepted worldwide as resistance standards.
