SG73S2ATTD10R0F是KOA品牌推出的0805封装厚膜贴片电阻,以精准阻值控制、宽温适应性及稳定性能为核心特点,广泛适配消费电子、工业控制、汽车电子等多领域的电路设计需求。
该电阻定位于中等精度、宽温适应性的通用精密厚膜电阻,既满足消费电子、通信设备对成本可控的批量应用需求,又可覆盖工业控制、汽车电子等对环境适应性要求较高的场景。其10Ω标称阻值、±1%精度及250mW额定功率,可作为限流电阻、分压电阻、反馈电阻等,在电源管理、信号采样、电流检测等电路中发挥关键作用。
标称阻值为10Ω,精度等级达±1%,相比常规±5%电阻,可显著减少电路误差积累,满足精密模拟电路(如信号放大、电压基准)的阻值一致性要求。
温度系数为±200ppm/℃,表示每变化1℃,阻值变化百万分之200。在全工作温度范围(-55℃~+155℃)内,阻值最大变化量仅为0.042Ω(210℃温差×200ppm),相对变化率0.42%,仍在精度范围内,保证宽温环境下的性能稳定。
工作温度范围覆盖-55℃至+155℃,符合工业级温度标准,可适应极端低温(如户外设备)、高温(如车载电子)环境的长期运行。
采用0805标准贴片封装(英制尺寸:2.0mm×1.2mm),适配自动化贴装生产线,可有效提升生产效率,同时满足高密度电路设计的空间要求。
通过丝网印刷电阻浆料、高温烧结形成电阻膜,兼具以下优势:
KOA作为全球知名电子元器件厂商,对该电阻进行了严格的可靠性测试,包括:
品牌保障下,该电阻可满足不同行业的质量要求,降低电路设计的售后风险。

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.
