Example: MicroMetrics part no. MTR-200RK-SR3-F-NA-G-0-T This would be a silicon body .020"x .020" x .010" single value through chip resistor with a total resistance tolerance of ± 1%, a Solderable gold back, and Tantalum Nitride as the resistor layer and a TCR of ± 150PPM. Example: MicroMetrics part no. MCR-10RK-SR2-F-E-B-1-T This would be a silicon body .030"x .030"x .010" two value ratio resistor with the first value resistance tolerance of ± 1% and the second, ratio resistor, tolerance being ±.1% of the first value. Resistance would be the total value of the two resistor. A Bare lapped silicon back, and Tantalum Nitride as the resistor layer and a TCR of ± 100PPM. Example: MicroMetrics part no. MIR-2R5K-SR3-J-NA-B-2-N This would be a silicon body .020"x .020" x .010" single valueTop pad to Top pad chip resistor with a total resistance tolerance of ± 5%, a bare silicon back, with NiChrome as the resistor layer and a TCR of ± 50PPM. Example: MicroMetrics part no. MMR-11RK-SR1-F-K-G-1-T This would be a silicon substrates device .038" x .038" x .010". It would have a total resistance of 11KOhms ± 1%. It would have ten large tops of 1KOhm ± 1% each and ten small tops of 100Ohms ± 10% each. It would have a solderable gold back with a TCR of ± 100ppm and a Tantalum Nitride resistive layer.

4) is the resistor value total % ± tolerance 5) is the 2nd resistor value total % ± tolerance (if applicable)
A) On Dual Value Ratio Resistors, (MCR), this is the res. ratio of the 2nd resistor (Ratio Res.) To value of the 1st resistor (Prime Res.). B) On Multi Tap Resistors (MMR). This is the tolerance of each of the small value Resistor Taps. The large value Resistor Taps are called out on (4).
