SG73S2ATTD10R0F 厚膜贴片电阻产品概述

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。

一、产品定位与核心应用方向

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。

二、关键性能参数详解

1. 阻值与精度

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。

2. 功率与电压

  • 额定功率:250mW,可支持低功耗电路的长期稳定工作;
  • 最大工作电压:200V,可适配高压环境下的电路设计(需注意实际功耗不超过额定功率,避免过功率损坏)。

3. 温度特性

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。

4. 环境适应性

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。

三、封装与工艺优势

1. 封装规格

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。

2. 厚膜工艺特性

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:

  • 成本可控:相比薄膜电阻成本更低,适合批量应用;
  • 稳定性好:电阻膜与陶瓷基底结合牢固,抗机械冲击、振动能力强;
  • 兼容性高:符合RoHS环保要求,无铅无镉,满足国际环保标准。

四、可靠性与品牌保障

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:

  • 高温存储测试(155℃/1000h):阻值变化率≤0.5%;
  • 温度循环测试(-55℃~+155℃/1000次):性能无明显衰减;
  • 湿度测试(85℃/85%RH/1000h):阻值稳定,无腐蚀现象。

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。

五、典型应用场景

  1. 消费电子:智能手机电源管理模块的限流保护、笔记本电脑电池充电电路的电流检测;
  2. 工业控制:PLC输入输出接口的信号调节、工业传感器(温度/压力)的信号放大反馈;
  3. 汽车电子:车载显示屏背光控制的电流调节、仪表盘信号处理的电压转换;
  4. 通信设备:基站电源负载均衡电路的电流分配、光纤收发器的信号匹配。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
