4、to +65C The 1433 Decade Resistors are convenient resistance standards for checking the accuracy of resistance-measuring devices. They are primarily intended for precision-measurement applications where accuracy, stability, and low-zero-resistance are important. They are used as components in dc and

5、audio frequency impedance bridges. Typical Value of Zero Impedance: Zero Resistance (Ro): 0.001 /decade at dc 0.04 /decade at 1 MHz Proportional to square root of frequency above 100 kHz Switch Capacitance: 1 pF between contacts Zero Inductance (Lo): 0. 1 H/decade + 0.2 H Switches: Continuous rotati
