Product Overview
The YC/TC series presented in this datasheet includes the YC (convex, flat) and TC (concave) chip resistor arrays designed for surface mounting, with lead-free terminations produced using a thick film process. These components are RoHS compliant, adhering to environmental standards prohibiting hazardous substances and reducing E-waste. With AEC-Q200 qualification, these chip resistor arrays are well-suited for high-reliability applications.
Applications
The chip resistors are intended for various applications, focusing particularly on computing and consumer electronics. They are used as terminal resistors in SDRAM and DDRAM, and are suitable for laptops, desktops, PDAs, PNDs, mobile phones, and other telecom equipment.
Product Features
Highlights of the YAGEO chip resistors include high efficiency in pick and place applications, low assembly costs, and space-saving on PCBs thanks to their small size. The arrays are made without any materials banned in manufacturing processes, and the epoxy used is halogen-free, contributing to their environmentally friendly profile.
Product Specifications
Resistance values range in this series, with clear rules for resistance coding provided in the “Resistance rule of global part number” table. Tolerances are set at ±1% or ±5%, with a specific code ‘J’ indicating a jumper. Products are packaged in either paper taping reel or embossed plastic tape reel, with 7- or 13-inch diameter options. The datasheet includes a comprehensive ordering guide for global part numbers, including series size, tolerance, packing type, temperature coefficient, and resistance value.
Ordering Information
Ordering codes should follow the structure given, as in the example: YC122-JR-07KL for a YC122 convex chip resistor array with a value of 1,000Ω at ±5% tolerance, or YC158TJR-07/00KL for a YC158T network with a value of 100,000Ω at ±5% tolerance, both supplied in 7-inch tape reels. The datasheet provides further details on resistance value notation and specification variations.
Environmental Compliance
All resistors from this series meet RoHS compliance, and the datasheet specifies the ‘LFP’ marking for lead-free processes. Custom labels can include ‘LFP’ or a specific symbol upon customer request, ensuring that users are aware of the lead-free status of the components.
Notes and References
Final notes clarify that all RSMD products from YAGEO meet RoHS compliance, and the internal label will mention the Lead-Free Process (LFP). Customized labels can also reflect this status based on customer requests.
