SC0805J7502F4ANRH 厚膜贴片电阻产品概述

SC0805J7502F4ANRH是信维通信(Sunway)推出的一款常规精度厚膜贴片电阻,采用0805封装,兼顾性能稳定性与成本优势,专为消费电子、工业控制等领域的基础电路设计,适配SMT自动化生产流程。

一、产品基本定位与核心身份

该电阻属于厚膜工艺贴片电阻,型号命名清晰对应关键参数:SC为信维通信电阻系列代码,0805为封装尺寸(英制0.08×0.05英寸),J代表阻值精度±5%,7502对应标称阻值75kΩ(实际阻值75kΩ,符合用户给定参数),F代表温度系数±100ppm/℃,ANRH为封装与可靠性代码。作为信维常规电阻产品,其设计目标是提供高性价比的稳定电阻解决方案。

二、核心电气性能参数详解

该电阻电气性能经过严格测试,关键指标如下:

  1. 阻值与精度:标称75kΩ,精度±5%(实际范围71.25kΩ~78.75kΩ),满足分压、偏置、限流等不敏感场景;
  2. 额定功率:125mW(1/8W),0805封装厚膜电阻常见等级,高温环境需降额(如155℃时降额至50%);
  3. 额定电压:150V,需注意功率限制(75kΩ在125mW下最大电压约96.8V,以功率与电压较小值为准);
  4. 温度系数(TCR):±100ppm/℃,温度每变1℃阻值变±0.01%,-55℃~155℃内最大漂移约±1.3%,稳定性可靠。

三、物理与封装特性

  1. 封装尺寸:0805封装(公制2.0mm×1.2mm×0.5mm),体积小巧,适配高密度PCB(便携设备、小型通信模块);
  2. 工艺特点:氧化铝陶瓷基片+厚膜印刷电阻浆料,高温烧结成型,成本低、一致性好;
  3. 电极设计:无铅锡镀层(RoHS环保),适配回流焊/波峰焊,焊接可靠性高;
  4. 保护结构:电阻层覆盖保护釉层,隔绝湿气、灰尘,提升耐候性。

四、环境适应性表现

  1. 工作温度:-55℃+155℃,覆盖工业环境(-40℃85℃)及部分高温场景(车载常温区、工业烤箱周边);
  2. 耐温特性:155℃时仍保持70%额定功率(降额后),阻值漂移小;
  3. 抗振动冲击:贴片式无引线结构,可承受10g以上振动加速度,适合户外、车载设备;
  4. 耐湿性能:保护釉层结合紧密,95%RH湿度下长期稳定工作。

五、典型应用场景

  1. 消费电子:手机、平板的音频偏置、传感器分压电路;
  2. 工业控制:PLC输入输出模块、传感器信号放大限流;
  3. 通信设备:路由器/交换机射频偏置、电源反馈网络;
  4. 汽车电子:车载音响、仪表盘背光、车身控制模块辅助电路(常温区);
  5. 电源领域:DC-DC反馈分压、线性电源限流(小功率场景)。

六、品牌与质量保障

信维通信电阻产品通过ISO9001认证,批次一致性严格,无铅环保符合RoHS与国内污染控制标准。针对批量应用,提供定制化参数验证与售后技术支持,适配出口与高端设备需求。

该电阻可快速匹配多数电子电路的基础电阻需求,是高性价比的常规选择。

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
