Overview of YAGEO YC/TC Series Chip Resistor Arrays
The YAGEO YC/TC Series datasheet describes the details of chip resistor arrays designed for various electronic applications. This series includes both YC and TC model resistors, known for their thick film process manufacturing and compliance with RoHS (Restriction of Hazardous Substances) requirements.
Product Applications
The resistor arrays are suitable for use in memory terminals like SDRAM and DDRAM, consumer electronics such as PDAs, mobile phones, telecom devices, and computing hardware varying from laptops to desktops.
Product Features
Highlighting their efficiency in automated placement and reduced assembly costs, these resistors are AEC-Q200 qualified, ensuring high reliability in components and equipment. They save printed circuit board (PCB) space and promote environmental sustainability by avoiding hazardous materials and being Halogen Free Epoxy. The resistors have several attractive attributes:
- Lead-free terminations for RoHS conformity
- Low tendency to hazardous waste production
- Compatibility with high component reliability standards
- No use of forbidden materials in manufacturing processes
Availability and Packaging
Resistors are available in multiple sizes and array/network configurations, thus catering to an extensive range of design requirements. The part number indicates series, size, tolerance, packaging type, temperature coefficient, taping reel, and resistance value. Packaging options include paper taping reel or embossed plastic tape reel, with standard 7-inch or 13-inch diameter sizes.
Tolerance and Resistance
The arrays have a tolerance designated by either ±5% or for specialized applications like jumper resistors, special ordering with a tolerance code of ‘J’. Resistance values are presented in a structured manner using 2-4 digits along with decimals represented by R, K, or M, with detailed rules outlined in the datasheet’s ‘Resistance rule of global part number’.
Ordering Information
Ordering examples illustrate how to specify a YC122 convex chip resistor array with a 1,000-ohm value at ±5% tolerance or a YC158T network with a 100,000-ohm value at the same tolerance, both in 7-inch tape reels. Additionally, the datasheet mentions default codes for ease of ordering, with ‘L’ as the system default code and ‘T’ specifically used for some models. A ‘jumper’ resistor can be specified by ‘IR’ for a 1-ohm value, with other values clearly defined within the datasheet.
Compliance and Customization
YAGEO’s RSMD products, including the YC/TC Series, align with RoHS compliance and embrace a lead-free process, indicated by ‘LFP’ on the internal 2D reel label. On customer request, customized labeling options are available for indicating lead-free process and resistance details.
