CSM

Product catalog summary
Overview: The document is a technical specification for the CSM Series Molded Metal Plate Sensing Resistors by Stackpole Electronics, Inc. It includes mechanical and electrical specifications, performance characteristics, and ordering information.
Mechanical Specifications: The document provides dimensions for two types of resistors, CSM0603 and CSM2512, in both inches and millimeters. It also includes a power derating curve illustrating the relationship between ambient temperature and rated power.
Features: The resistors are high power metal alloy current sense resistors with a molded package for superior heat dissipation. They have a typical inductance of less than 5nH, making them ideal for power supplies and motor drives.
Electrical Specifications: The CSM0603 has a power rating of 0.33W and a maximum current of 5.6A, while the CSM2512 has a power rating of 3W and a maximum current of 54.8A. The operation temperature range for CSM0603 is -55ºC to +155ºC, and for CSM2512, it is -55ºC to +170ºC. The temperature coefficient of resistance (TCR) is ±100 ppm/ºC for CSM0603 and ±75 ppm/ºC for CSM2512.
Performance Characteristics: The document outlines various test conditions and limits, including load life, short time overload, moisture no load, temperature cycle, resistance to soldering heat, solderability, high temperature exposure, low temperature storage, substrate bending, and insulation resistance.
Solder Pad Dimensions: Specific dimensions for solder pads are provided for both CSM0603 and CSM2512 types.
Ordering Information: The document explains the coding system for ordering, including size, tolerance, resistance value, and packaging. It also specifies storage conditions with a temperature range of 5ºC to 35ºC and relative humidity of 40% to 75%.
