Application Notes


The FRSM ultra high precision resistor series from VFR offers a resistance range between 100ฮฉ and 5kฮฉ, all in a small 0603 surface-mount package with wrap-around terminations. These resistors utilise VFR’s newest Z-1 Bulk Metalยฎ foil resistor technology for improved load life stability (up to 25ppm) and higher working temperatures (balanced temperature characteristics over a range from -55ยฐC to more than 175ยฐC). They have nominal temperature coefficients of resistance of ยฑ0.05ppm/ยฐC typical between 0ยฐC to +60ยฐC and ยฑ0.2ppm/ยฐC typical between -55ยฐC to +125ยฐC (+25ยฐC reference) with tolerances available down to ยฑ0.01% between 250ฮฉ and 5kฮฉ.

  • Ultra high precision wrap-around bulk foil chip resistor
  • Available in any resistance between 100ฮฉ and 5kฮฉ
  • 0603 package
  • Tolerances as low as ยฑ0.01% over the resistance range of 250ฮฉ up to 5kฮฉ
  • TCR as low as ยฑ0.2ppm/ยฐC between -55ยฐ and +125ยฐC, +25ยฐC ref.
  • Voltage rating 22V
  • Power rating of 0.1W at +70ยฐC
  • Load life stability of 25ppm typical at 70ยฐC, 2000h at rated power (50 ppm typical at 70ยฐC, 10000h at rated power)
  • Thermal stabilization time <1s (nominal value achieved within 10ppm of steady state value)
  • Electrostatic discharge (EDS) of at least to 25kV
  • Short time overload of โ‰ค0.005% typical
  • Rise time as low as 1ns, effectively no ringing
  • Current noise of <0.010ยตVRMS/V of applied voltage (<-40dB)
  • Non-hot spot design
  • Terminal finishes available: lead (Pb) free, tin/lead alloy

Bulk Metalยฎ Foil Resistors

Bulk Metalยฎ Foil resistors, developed by Dr. Felix Zandman in 1962, are the gold standard for the electronic industry. With essentially zero TCR, zero PCR and extremely robust construction, they are the logical choice for all applications requiring unquestioned reliability and stability.
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 โ€” foil, thin, and thick film โ€” 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 Metalยฎ 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.
