Sunway SC0603F7503F2BNRH 厚膜贴片电阻产品概述

一、产品型号与核心定位

SC0603F7503F2BNRH是Sunway(信维通信) 推出的通用型厚膜贴片电阻,针对小体积高密度PCB设计、宽温工作场景优化,兼顾精度与可靠性。型号编码可对应核心参数:

  • "SC"为Sunway电阻系列标识;
  • "0603"对应英制0603封装(公制1.6mm×0.8mm);
  • "7503"代表标称阻值750kΩ(750×10³Ω);
  • "F"标识精度等级±1%;
  • 后缀"2BNRH"关联温度系数等性能参数,与已知的±100ppm/℃匹配。

二、关键电气性能参数详解

该电阻的核心电气参数适配多数工业与消费电子需求,具体说明如下:

  1. 阻值与精度:标称750kΩ,精度±1%,实际阻值范围为742.5kΩ~757.5kΩ,无需额外校准即可用于模拟信号调理、数字电路分压等场景;
  2. 功率与电压:额定功率100mW,最大工作电压75V。需注意实际功耗需满足公式(P=I²R=U²/R),若电路电压接近75V,需控制电流≤133μA(75V/750kΩ),避免过载;
  3. 温度系数:±100ppm/℃,即温度每变化1℃,阻值变化±0.01%。以工作温度范围-55℃~+155℃计算,温差210℃时阻值最大变化±2.1%,仍在精度允许范围内,保证宽温下电路性能稳定。

三、封装与物理特性

采用0603表面贴装封装,公制尺寸为1.6mm(长)×0.8mm(宽)×0.45mm(厚,典型值),重量约10mg,具备三大优势:

  • 小体积:适配智能手机、智能穿戴、小型工业模块等高密度PCB设计,节省空间;
  • 自动化适配:支持SMT贴装,适合大规模量产,降低生产升本;
  • 厚膜工艺:相比薄膜电阻成本更低,且抗脉冲能力更强,适合普通电子设备稳定工作。

四、环境适应性与可靠性设计

该产品针对 harsh环境优化,可靠性经过多项验证:

  1. 宽温范围:-55℃+155℃,覆盖汽车电子(-40℃+85℃)、工业控制(-20℃~+85℃)、户外设备等场景;
  2. 可靠性测试:
    • 负载寿命测试:1000小时额定功率下,阻值变化≤±0.5%;
    • 温度循环测试:-55℃~+155℃循环500次,阻值变化≤±0.2%;
    • 湿度测试:85℃/85%RH环境下1000小时,阻值变化≤±0.3%;
  3. 环保合规:符合RoHS 2.0、REACH标准,不含铅、镉等有害物质,适配全球市场。

五、典型应用场景

结合参数特性,该电阻适用于以下场景:

  1. 汽车电子:仪表盘显示电路、车身控制模块(BCM)模拟信号处理、胎压监测(TPMS)传感器接口;
  2. 工业自动化:PLC模拟输入模块、传感器信号调理、小型电机驱动限流;
  3. 消费电子:智能手机射频匹配、智能穿戴电源管理、蓝牙耳机信号滤波;
  4. 通信设备:小型基站射频前端、路由器电源分压、光纤收发器偏置电路。

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
