Product Overview
Victoreen part number 7611920 is an RX-4 / RX4B series 1.47 megohm precision resistor sealed inside a protective glass envelope with axial wire leads. Engineered for high-impedance applications, the hermetic glass enclosure isolates the resistive element from atmospheric moisture, surface contamination, and leakage currents.
Key Features
- Resistance value: 1.47 MΩ (1.47 Megohm)
- Hermetically sealed glass envelope construction
- Axial wire lead configuration
- Marked RX4B-VICO and 7611920
- Federal stock reference NSN 5905-578-4549
Applications
- High-voltage divider networks and radiation detection instrumentation including Geiger counters and ionization chambers.
- Electrometer input stages, vacuum tube monitoring circuits, and high-impedance test equipment.
- Restoration projects and bench experiments requiring stable high-megohm resistance without ambient humidity drift.
Frequently Asked Questions
What is the benefit of the glass envelope construction?
The hermetic glass body seals the internal resistive element against humidity, dust, and atmospheric contaminants that could otherwise cause surface leakage in high-resistance circuits.
What mounting configuration does this resistor use?
This resistor features standard axial wire leads suitable for point-to-point wiring, turret boards, or through-hole PCB mounting.
How does the RX4B-VICO package differ from standard metal film resistors?
The RX4B-VICO uses an elongated glass cylinder enclosure with sealed end caps and axial wire leads, requiring more physical clearance than standard molded resistors while providing hermetic isolation at high impedance levels. The price-break table on this page gives the price per piece at each quantity.
Victoreen knew that at a million ohms and beyond, ordinary air is a leak waiting to happen. Slip this sealed tube into your circuit and let the glass do the heavy lifting.
