Product catalog summary
Overview: The document is a technical data sheet for the AT series of thin film chip resistors, specifically designed for automotive applications. These resistors are available in sizes 0402, 0603, 0805, and 1206, with tolerances ranging from 0.1% to 1% and temperature coefficients from 25 ppm/°C to 50 ppm/°C. They are RoHS compliant and AEC-Q200 qualified, ensuring high reliability and environmental safety.
Specifications: The resistors are constructed with a metal film layer on a ceramic body, providing high precision and stability. They are designed to operate within a temperature range of -55°C to +155°C. The power ratings vary by size: 1/16W for 0402, 1/10W for 0603, 1/8W for 0805, and 1/4W for 1206. The maximum working voltage and overload voltage also vary by size, with the highest being 200V and 400V respectively for the 1206 size.
Applications: These resistors are suitable for use in automotive electronics, industrial and medical equipment, test and measuring equipment, and telecommunications.
Features: Key features include superior resistance to sulfur-containing atmospheres, moisture sensitivity level of MSL 1, and halogen-free epoxy. The resistors are designed to reduce environmentally hazardous waste and ensure high component and equipment reliability.
Ordering Information: The global part number is structured to include size, tolerance, packaging type, temperature coefficient, taping reel, and resistance value. An example ordering code is provided for clarity.
Marking and Construction: The document details the marking conventions for different sizes and series, as well as the construction process involving multiple layers for optimal solderability.
Dimensions and Electrical Characteristics: Detailed dimensions for each size are provided, along with electrical characteristics such as resistance range and temperature coefficient of resistance (TCR).
Testing and Reliability: The resistors undergo various tests to ensure reliability, including short time overload, high temperature exposure, moisture resistance, biased humidity, operational life, resistance to soldering heat, thermal shock, and solderability. Each test has specific conditions and requirements outlined.
Legal Disclaimer: Yageo disclaims liability for errors or inaccuracies in the document and states that the information is intended for customers with the requisite knowledge to determine product suitability for specific applications.
