Alpha CSR Series
Click Image for Gallery
The CSR working standard resistor series from Alpha electronics uses Bulk Metal® foil resistance elements, which have the same excellent stability and low temperature coefficient of resistance as the ASR series. Alpha's Bulk Metal® foil offers a precision that cannot be matched by any other resistance material. The CSR series can be customised to any resistance value from 0.001Ω up to 100MΩ.
- Standard Resistor
- Wide resistance range available from 0.001Ω to 100MΩ
- Custom resistance values are available on request
- Compact construction designed for simple operation and storage
- Terminals aligned in a single row for easier wiring and placement
- Low cost, high performance
- Power rating of up to 0.5W (CSR-1N0, CSR-10N and CSR-R10 models)
- Working temperature range of +18°C to +28°C
- Storage temperature range of 0 to +50°C
The CSR is designed for equal ease of use either in laboratory conditions or on the production floor. The construction of the CSR series is designed to give ease of transport and storage, and can be used in normal air environments without the need for oil bath submersion.
The CSR series has a weight of approximately 300g and dimensions of 100mm x 65mm x 66.5mm.

| Resistor Stability Put to the Test (Demo Video) In this video, host Richard Zuratt from VPG 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. |

| A head to head comparison of the survival rates of precision thin film nichrome (NiCr) resistors versus VFR Bulk Metal Foil resistors in a high humidity environment. 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. |
|
| 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. |
