ARG05FTC2R50是光颉(Viking) 推出的一款0805封装薄膜贴片电阻,属于高精度小功率电阻范畴。型号中“2R50”明确对应阻值2.5Ω,针对需要稳定阻值输出、小体积集成的场景设计,广泛适配消费电子、工业控制等多领域电路需求,是电子设计中2.5Ω阻值场景的实用选型。
ARG05FTC2R50的核心参数可从四个维度梳理,满足多数中低功率电路的设计要求:
阻值为2.5Ω,精度达**±1%**——这一精度在薄膜电阻中属于主流可靠级别,能有效减少电路中因阻值偏差导致的信号失真或功率误差,适合对阻值一致性要求较高的采样、分压等电路。
额定功率125mW,是0805封装贴片电阻的常见功率规格;最大工作电压150V,需注意电路中实际施加电压需低于此值,避免击穿损坏。
温度系数为**±25ppm/℃,意味着每升高1℃,阻值变化仅约0.0625μΩ,温变稳定性优异;工作温度范围覆盖-55℃~+155℃**,可适配低温户外、高温工业环境,无需额外温区补偿。
采用0805英制封装(对应公制2012,尺寸约2.0mm×1.2mm),体积小巧,适合高密度PCB布局,可有效节省电路板空间,适配便携设备、小型模块的集成需求。
ARG05FTC2R50的性能优势源于薄膜电阻的固有特性,结合参数设计,主要适配以下场景:
为确保ARG05FTC2R50的长期可靠性,使用时需注意以下几点:
光颉(Viking)作为专业被动元器件制造商,ARG系列电阻符合RoHS、REACH等环保标准,批量产品阻值一致性误差控制在±0.5%以内(优于标称±1%),可满足量产需求。此外,该电阻通过了常规可靠性测试(如温度循环、湿度老化),适合对品质要求较高的中高端电路设计。
总结来看,ARG05FTC2R50是一款“小体积、高精度、宽温可靠”的薄膜贴片电阻,适配多领域电路需求,是电子设计中2.5Ω阻值场景的优质选型。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
