AC series

Product catalog summary
Overview: The document outlines specifications for the AC series of thick film chip resistors, which are automotive grade, RoHS compliant, and halogen-free. These resistors are suitable for general-purpose applications, car electronics, and industrial use, available in sizes from 0201 to 2512.
Specifications: The resistors offer tolerances of ±5%, ±1%, and ±0.5%, are AEC-Q200 qualified, and have a moisture sensitivity level of MSL 1. They comply with J-STD-020D soldering standards and are constructed with a ceramic substrate and protective overcoat.
Ordering Information: The global part number includes size, tolerance, packaging type, temperature coefficient, taping reel, and resistance value. For example, AC0402FR-07100KL represents a 100 KΩ resistor with ±1% tolerance.
Marking: Marking rules vary by size and series, with no markings for smaller sizes like AC0201 and AC0402, while larger sizes have specific digit markings.
Construction: Resistors are built on a ceramic body with internal metal electrodes and a resistive glaze, laser-trimmed for precision, and covered with lead-free glass.
Dimensions: Detailed dimensions are provided for each size, including length, width, height, and electrode spacing.
Electrical Characteristics: Operating temperature range is -55°C to +155°C, with power ratings, maximum working voltages, and overload voltages specified for each type. Resistance range and temperature coefficients are detailed.
Tests and Requirements: Resistors undergo tests such as high temperature exposure, moisture resistance, biased humidity, operational life, resistance to soldering heat, thermal shock, and ESD, each with specific conditions and criteria.
Packing and Packaging: Available in paper or embossed taping reels, with quantities varying by size and reel dimension.
Solderability: Follows AEC-Q200 Test 18 and J-STD-002 standards, requiring ≥95% tin coverage with no visible damage.
Board Flex: AEC-Q200 Test 21 involves bending tests on a 90mm glass epoxy resin PCB, with requirements varying by chip size.
Temperature Coefficient of Resistance (T.C.R.): Measured per MIL-STD-202 Method 304, with a formula provided for calculation in ppm/°C.
Short Time Overload: Conducted per IEC60115-1 4.13, applying 2.5 times the rated voltage for 5 seconds at room temperature.
Sulfur Resistance (FOS): Tested using ASTM-B-809-95, exposing resistors to sulfur vapor for 500 hours at 60±2°C.
Revision History: Document changes from version 0 to 5 include updates to test methods, resistance ranges, and product features.
Legal Disclaimer: Yageo disclaims liability for errors in product information and advises customers to ensure product suitability for their applications, especially in critical safety-related uses.

Product specification Chip Resistor Surface Mount CONSTRUCTION The resistors are constructed on top of an automotive grade ceramic body. Internal metal electrodes are added at each end and connected by a resistive glaze. The resistive glaze is covered by a lead-free glass. The composition of the glaze is adjusted to give the approximately required resistance value and laser trimming of this resistive glaze achieves the value within tolerance. The whole element is covered by a protective overcoat. Size 0603 and bigger is marked with the resistance value on top. Finally, the two external terminations...
