The General Radio 1432-B Decade Resistor was in Catalog S (1965) only.
The Type 1432-B is decade resistance box is comprised of six Type 510 decade resistance units in series for a total resistance of 1,111,110 Ω. The 510 decade units use an 11 position switch, the first position shorts the decade the following positions increase the resistance by a factor of 1. The decade switch is what's referred to as a make before break configuration, regardless of the position there's always a continuity at it's terminals. The terminals are Type 938 equipped with a shorting link to the case. The decades are housed in an aluminum case shielded and insulated from its resistance terminals.
Specifications
- Total Resistance: 1,111,110 Ω
- Number of Decades: 6
| Decade Unit Type | Total Resistance Ohms | Resistance / Unit Ohms | Accuracy per increment | Maximum Current | Power/step |
|---|---|---|---|---|---|
| 510-B | 10 | 1 | ±0.15% | 800 mA | 0.6 W |
| 510-C | 100 | 10 | ±0.05% | 250 mA | 0.6 W |
| 510-D | 1,000 | 100 | ±0.05% | 80 mA | 0.6 W |
| 510-E | 10,000 | 1000 | ±0.05% | 23 mA | 0.5 W |
| 510-F | 100,000 | 10,000 | ±0.05% | 7 mA | 0.5 W |
| 510-G | 1,000,000 | 100,000 | ±0.05% | 2.3 mA | 0.5 W |
