Jual GENRAD 1491 D G PRECISION DECADE INDUCTOR



Spesifikasi GENRAD 1491 D G PRECISION DECADE INDUCTOR

 

Features

  • Most accurate decade inductor commercially available, accuracy's as good as 0.8%
  • Inductance range from 1 mH or 100 µH to 11 H
  • Shielded toroidal cores for small mutual inductance and minimal effect from external fields
  • Sealed against moisture for long-term stability
  • High-Q, 200 and above

 

Specification

Range: 
1491D Decade inductor, 4 decades, 11.11 H total inductance, 1 mH per step 
1491G - Decade inductor, 5 decades, 11.111 H total inductance, 100 µH per step

Accuracy (Low Frequency, Low Signal Level):

Model 100 µH 1 mH 10 mH 100 mH 1 H 
1491-DN/A2%1.6%0.8%0.8%
1491-G2%2%1.6%0.8%0.8%


Frequency Characteristics: Percentage increase in effective series inductance (above the zero-frequency value, Lo) may be obtained by interpolation in accompanying graph (see Figure 2 on datasheet or in manual) for any setting to the highest-value decade used, when LOW terminal is grounded to cabinet.

Zero Inductance: Approximately 1 μH

Maximum Voltage: 500V rms. Switch will break circuit at 500V if turned rapidly, but voltages above 150V may cause destructive arcing with switch between detent positions
