Product catalog summary
Overview: This document is a technical datasheet for the SR series of automotive-grade surge chip resistors, detailing specifications, applications, features, and testing requirements. The resistors are available in various sizes and are RoHS compliant and halogen-free.
Specifications: The SR series includes sizes 0402, 0603, 0805, 1206, 1210, 1218, 2010, and 2512. They are available with tolerances of 20%, 10%, and 5%. The resistors are constructed using a thick film process with lead-free terminations.
Applications: These resistors are suitable for telecommunications, power supplies, and car electronics, offering high reliability and reduced environmental impact.
Features: The SR series is AEC-Q200 qualified, superior in pulse and surge withstanding voltage, and classified as MSL 1. They are designed to reduce hazardous waste and ensure high component reliability.
Ordering Information: The global part number includes details such as size, tolerance, packaging type, temperature coefficient, taping reel, and resistance value. An example is provided for ordering a specific resistor.
Construction: The resistors are built on a ceramic body with metal electrodes and a resistive glaze, covered by a protective overcoat. External terminations are made of Ni/matte tin.
Dimensions: Detailed dimensions for each resistor size are provided, including length, width, height, and terminal dimensions.
Electrical Characteristics: The resistors operate within a temperature range of -55°C to +155°C, with varying power ratings and voltage specifications depending on the size.
Testing and Requirements: The datasheet outlines various tests such as temperature coefficient of resistance, short time overload, high temperature exposure, humidity, life, resistance to soldering heat, temperature cycling, solderability, and board flex. Each test includes specific methods, procedures, and requirements.
Revision History: The document includes a revision history detailing updates and changes made to the datasheet over time, ensuring compliance with standards and improvements in product specifications.
