Bulk Metal® Foil (BMF) technology out-performs all other resistor technologies available today for applications that require high precision and high stability, and allows production of customer oriented products designed to satisfy challenging and specific technical requirements. The BMF provides an inherently low and predictable Temperature Coefficient of Resistance (TCR) and excellent load life stability for high precision analog applications.
One of the most important parameters influencing stability of SMD resistor is the Temperature Coefficient of Resistance (TCR). Although the TCR of foil resistors is considered extremely low, this characteristic has been further refined over the years. The VSMP Series utilizes ultra high precision Bulk Metal® Z-Foil. The Z-Foil technology provides a significant reduction of the resistive element’s sensitivity to ambient temperature variations (TCR) and to self heating when power is applied (Power Coefficient of Resistance, or PCR). Along with the inherently low PCR and TCR, Z-Foil technology also provides remarkably improved load life stability, low noise and tight tolerances.
Vishay Foil Resistors (VFR) introduces a new line of Ultra Precision Bulk Metal® Z1-Foil technology: wraparound SMD resistor with extended pads for high temperature up to + 225 °C (working power: to 330mW at +200 °C).
The Z-Foil technology provides a significant reduction of the resistive components sensitivity to ambient temperature variations and applied power changes. Designers now can guarantee a high degree of stability and accuracy in fixed resistor applications using solutions based on Vishay’s revolutionary Z-Foil technology for SMD resistor.

Today, designers of circuits are demanding voltage dividers that approach the ideal in performance: stable, high speed, high accuracy components that will operate with assured, predictable reliability for years in a variety of environments. Vishay Foil voltage dividers and resistor networks are meeting those demands and add the dimensions of convenience and economy to resistor needs. Our long experience relieves the circuit designer of the complicated, costly and wasteful procedure of calculating the value of individual resistor components, ordering and then stabilizing, aging or matching these units, and literally assembling and testing his own resistor arrays. The Vishay Foil Resistors approach to dividers is simple and straight-forward, our solution consists of any combination of resistors, and the end result is what matters. As a consequence, the only data we require from the designer is the overall electrical performance specifications, the environment operational, and the desired physical requirements
Key Benefits
● Absolute Temperature Coefficient of Resistance (TCR):±0.05 ppm/ºC (0ºC to +60ºC) typical with Z-Foil±0.2 ppm/ºC (-55ºC to +125ºC, +25ºC ref.) typical with Z-Foil
● TCR tracking: 0.1 ppm/ºC
● Power Coefficient of Resistance (PCR) tracking “∆R due to self heating”: 5 ppm at rated power
● Resistance tolerance (absolute and match): ±0.005%
● Load life ratio stability:

Shunts should be mounted with manganin resistive blades in a vertical position in order to promote the free convectional Ow of air. If vertical mounting is not practical, forced air cooling or adding heat sinks to the blocks can reduce the operating temperature. The manganin blades must never exceed +145°C, otherwise permanent resistance change may occur.
When current of 100A or greater is passing through the shunt, the major portion of heat generated is dissipated by conduction through the shunt terminal blocks into the connecting buss bar or cable. Therefore it is necessary to insure that good contact is made between the shunt terminal blocks and the conductor terminals and that the conductors have adequate cross section to keep the temperature of the shunt from exceeding 145°C ( 125°C recommended ).
If the shunt is mounted in an enclosure, care must be taken to ensure adequate cooling. If the power density is greater than 1/4 watt per square inch of the enclosure surface for all enclosed devices, additional cooling must be supplied in the form of air vents or fans.
Shunts also must be installed in a way that protects them from thermal expansion forces produced from
buss bar or short-circuit forces. Flexible wiring may be required in high pulse current, high vibration, or high temperature applications.
Where possible, all shunts should be mounted on the ground side of the circuit. For circuits above 750VDC, RS shunts must be mounted on the ground side due to the dielectric strength of the shunt base.
Applications :
Solar Generators, Wind Power, Heavy Industry, Welding, Electroplating, Battery Chargers, etc.
Features :
• High Precision: ± 0.25%, 0.1%, 1%, 5%• Current Range: 1A to 1200A

INTRON is synonymous with precision and stability in the Indian Electronics Industry for the last 40 years. It was set up by Dr.Wasudeo Jirafe, a pioneer in the field of microelectronics with a dream of bringing high precision metal foil resistor products to the Indian industry. We are on our way to fulfilling this vision by bringing the ultra high precision foil resistor to India. Intron manufactures precision low tolerance and tight TCR radial resistors and thin film resistor networks in India with In-house design facility, for custom designed resistor networks including hybrid networks. The radial resistors manufactured by INTRON have an inbuilt precision and the low tolerance (0.05%) and TCR (5ppm/°C) is obtained by process capability and does not rely on a selection process. Intron is now in a position to manufacture ultra precision foil resistor in SMD as well as through hole with tolerance down to 0.005%; which provide extremely low temperature coefficient of resistance (TCR) of 0.05ppm/°C; exceptional long-term stability to ± 0.0025% and electrostatic discharge (ESD) protection to at least 25 kV. Intron will also be distributing the complete range of Vishay Foil Resistors portfolio which comprises products in a variety of resistor configurations and package types to meet the needs of a wide range of applications such as medical electronics, semiconductor equipment, precision measuring instruments, aerospace, and military applications. Intron will make available any odd value resistor and in any small quantity for prototype development and will provide expert applications assistance to design engineers to help them improve the performance of their end products.
