Passive electronic components such as resistors, capacitors and inductors form a small but significant part of the mission critical supply chain of defense and aerospace electronics.

The major circuit applications that employ resistors in defense electronics are:

• Power Supplies
• Communication and Navigation (Satellites, surveillance, Sonar, Radar)
• Computing, Data storage and Networking
• Displays and Controls
• Ammunition and missile systems
• Optics and Sensors

This sector requires resistive elements that guarantee fail-safe usage and very high reliability even at abnormal conditions such as:

• Very low or very high temperature (Below 500C and above 1500C)
• Harsh environmental conditions or natural disasters such as floods, earthquakes
• High voltage (Above 500V)

The various types of resistors employed in these defense applications can be broadly classified as follows:

• Wire-wound resistors for power supplies, calibration equipment and circuit breakers.
• Nichrome metal film, Tin-oxide and bulk metal foil resistors for Avionics, flight control systems, Microwave communication equipment.
• Resistor loadbanks for reliability testing of generators and power sources.
• Variable wire-wound resistors for computer, antenna, flight control, and bomb navigation systems.
