YC/TC series

Product catalog summary

Product Overview: The document outlines the specifications for YC/TC series chip resistor arrays, which are surface mount resistors adhering to RoHS standards. These resistors come in various sizes and configurations, including convex (YC) and concave (TC) types, and are intended for use in electronic devices such as computers, mobile phones, and telecom equipment.

Specifications: Available in sizes from 102 to 358, these resistors have tolerances of ±1% and ±5%. They are packaged in paper or embossed plastic tape reels, with resistance values indicated by a specific coding system. Constructed using a thick film process on a ceramic body, they feature metal electrodes and a protective epoxy coating.

Applications: Suitable for SDRAM and DDRAM terminals, laptops, desktop computers, PDAs, PNDs, and other consumer electronics, these resistors offer low assembly costs, high reliability, and space-saving on PCBs.

Features: The resistors are RoHS compliant, lead-free, and contain no forbidden materials, designed to reduce environmentally hazardous waste and provide high component reliability. They feature halogen-free epoxy and are efficient for pick and place applications.

Ordering Information: Details the global part number system for ordering, including series, size, tolerance, packaging type, temperature coefficient, taping reel, and resistance value, with an example provided.

Electrical Characteristics: Operating within a temperature range of -55°C to +155°C, power ratings vary by type. The rated voltage is determined by the formula V = (P x R) or the maximum working voltage, whichever is less.

Testing and Requirements: Various tests and requirements are outlined, including life endurance, high-temperature exposure, moisture resistance, thermal shock, short-time overload, and board flex/bending, each with specific procedures and acceptance criteria.

Dimensions and Construction: Provides detailed dimensions for each resistor type and construction details, including the use of noble metal in the resistive element and protective coatings to prevent environmental influences.

Test Board Specifications: Only one board bending required with a 3 mm bend, bending time specified as 60±5 seconds, ohmic value checked during bending with a tolerance of ± (1%+0.05 Ω), jumper resistance should be less than 50 mΩ, and no visible damage should occur.

Test Conditions, Procedures, and Requirements:

Solderability - Wetting: Follows IPC/JEDECJ-STD-002B test B and IEC 60068-2-58 standards, no electrical test required, magnification at 50X, SMD conditions include aging at 155 °C for 4 hours and a lead-free solder bath at 245±3 °C for 3±0.5 seconds, requirement: well tinned (≥95% coverage) and no visible damage.
Solderability - Leaching: Follows IPC/JEDECJ-STD-002B test D and IEC 60068-2-58 standards, lead-free solder at 260 °C for 30 seconds immersion time, requirement: no visible damage.
Resistance to Soldering Heat: Follows MIL-STD-202G-method 210F and IEC 60068-2-58 standards, condition B with no pre-heat of samples, lead-free solder at 270 °C for 10 seconds immersion time, devices are fluxed and cleaned with isopropanol, requirement: ± (1%+0.05 Ω) and <50 mΩ for Jumper, no visible damage.
