Current Sensing Chip Resistors

State of the Art Inc. (SOTA) has introduced two series of true full Kelvin 4-terminal low value chip resistors suitable for current sensing applications.

The S2512FK Series measures .250 in. x.125 in. x .030 in. and is rated at 2W. The S2010FK Series measures .200 in. x 100 in. x .030 in. and is rated at 1W. Both series offer range values from .01 ohm¸ to 1 ohm¸ and feature tolerances as tight as 1%.

Standard features include marking of resistance value and current/sense terminals and wrap-around nickel barrier terminations. Options include high reliability screening and epoxy bondable terminations.

Voltage ratings are 150V (2010FK) and 200V (2512FK). Their operating range is from -55¡ã C to 125¡ã C.

Reliability is assured by extensive in-house testing¡ªusers can select from a wide variety of testing options. Custom testing to customer specifications is also available. The chip resistors are designed for use in a wide range of high reliability applications, including medical electronics, defense systems, microwave communications, aerospace electronics, and satellite systems.

Pricing is generally under $1.00 in manufacturing quantities. Current lead time is eight weeks, but SOTA maintains more than 50 million resistors in stock. Delivery on stock items is two business days ARO.
