Please contact factory or sales office for your special requirements. For dealing with your application we need the following information: Pulse shape and repetition rate max. peak power Pulseduration or time constant max. peak voltage Resistance value If already selected: Type or series or technology or preferred style 10 70 80 90 100 [m ] Design Notes for Current Sense Resistors General: These devices are of non-wound construction and made from flat resistive alloy wire. The resistor`s specification depends on the material and the choosen dimensions, namely specific-resistance, thermal conductivity and temperature coefficient are of importance. 1. Standard, leaded types, KN-family Types KN 350 ... KN 354 The KN-resistors" are available in standardized sizes with choices of open-frame and ceramic cased types. Copper leads are welded to the resistive element for board assembly. The lower the resistance value, the more influence of the copper leads, the higher the TC! If the TC is of concern in a given application, a vertical style of the KN-family should be used (type 35X-009). In this case the influence of the copper wire is almost eliminated. Marking 3,5+1 VITROHM offers a range of low-ohm resistors for current sensing applications, resistance ranges typically from 1 milliohm to 100 milliohms. M Measuring point - power and current rating Attention should be given to the following: - resistance value The value is specified over a given measuring length". Between the two measuring points lies the element plus some copper-wire for contact purposes. If the actual used total length of the resistor in the application differs from this specified length, the influence of the copper wire of 0.4 m per centimeter must be considered. The KN-resistors" are standard products with a fixed given power rating (P70). Nevertheless, current rating can be of concern, especially if overload or pulse conditions can occure. The current limit is defined by the current density, and 100 A per mm2 are considered absolute maximum in power electronics. With a 0,8 mm diameter copper wire, the current limit is 50 A. With respect to reliability, the welding junction between copper and resistive alloy should not carry more than 20 A continuously. The 50 A limit may not be exceeded even under pulse conditions. 2. Semi-customized types, LPS-family Types LPS 355 ... LPS 359 VITROHM provides tools to produce U-shaped lowohm resistors for direct board mounting. - temperature coefficient Typically the temperature coefficient of the resistive element ranges around 150 ppm/oC (ask factory for details). However, the copper wire is part of the effective resistance and influences the TC between the contacts. 24 The solder-tags (1 or 2 per side) are of given dimensions, the size of the final unit is designed in accordance with the applicational requirements. If the demand for a shunt-resistor justifies a customized solution, the LPS-family offers a variety of possibilities.
