Applications

The ATV series from Alpha Electronics is a current / voltage (I/V) conversion adaptor used to accurately measure current using a voltage meter. Its small, lightweight construction enables it to be easily attached directly to a voltage meter for ease of operation.

  • Current / voltage conversion adaptor
  • Compact size
  • Lightweight
  • Full resistance range available from 1Ω to 100kΩ
  • Temperature coefficient of ±2.5 ppm/°C
  • ±0.1% accuracy
  • Maximum working current of up to 0.5A (ATV-1R0 1Ω model)
  • Power rating of 0.1W (0.25W for the ATV-1R0 model)

 

Each model corresponds to a set resistance value and maximum working current.

Place holder video for YouTube video Resistor Stability Put to the Test (Demo Video)

In this video, our host Richard Zuratt puts the stability of the three major resistor technologies — foil, thin, and thick film — to the test. Each resistor type is subjected to an overload pulse and its change in resistance value is recorded. Due to the homogeneous nature of the VPG Bulk Metal® Foil resistor, it is the only of the three to experience no change from the high power pulse. This demonstrated performance makes foil resistors the technology of choice for critical applications where long-term stability and survivability are paramount.

Place holder video for YouTube video Advantages of Using Bulk Metal® Foil Resistors in High-Humidity Environments

All resistors that are based on nichrome, which is a category that includes both thin film devices and Bulk Metal Foil resistors, are susceptible to electro-chemical corrosion or etching when placed in a high humidity environment and powered with a very low wattage. But since the nichrome element of a Bulk Metal Foil resistor is hundreds of times thicker than the element in a thin film device with the same value, it will last much longer under these conditions. This video shows the actual etching process and survival times for thin film and foil nichrome resistive elements as they are tested in 100% humidity conditions.

Place holder video for YouTube video Comparison Testing of Chip Resistor Technologies Under High Vibration

Surface-mount resistors suffer physical stresses when exposed to high vibration or thermally unstable environments. Failure modes commonly occur in welds, solder joints, connectors, and terminations, ultimately resulting in circuit failure. In this demonstration, vibration-table-mounted boards are subjected to ±2° deflection 25 times per second and monitored for any ΔR > 0.1%. All the chip resistors failed in 2 to 12 minutes (8K to 16K cycles). But the Alpha MPP molded Bulk Metal® Z-Foil resistor with flexible terminations experienced over a million cycles with no change in resistance.
