SC0603F7502F2BNRH 厚膜贴片电阻产品概述

一、产品基本属性与命名解析

SC0603F7502F2BNRH是信维通信(Sunway)推出的工业级厚膜贴片电阻,针对高密度PCB贴装场景设计,命名遵循行业通用规则,各部分核心含义如下:

  • SC:信维通信电阻产品系列标识;
  • 0603:封装尺寸(英制标准,对应公制1608,即长1.6mm×宽0.8mm);
  • F:技术类型(厚膜电阻,采用陶瓷基板+钌基电阻浆料工艺);
  • 7502:阻值代码,对应标称阻值75kΩ(注:行业三位阻值代码为“有效数字+倍率”,75kΩ实际应为753代码,本产品以官方参数为准);
  • F2:性能标识(±1%精度、±100ppm/℃温度系数);
  • BNRH:可靠性等级(0603封装、工业级耐环境能力)。

二、核心电气性能参数

该电阻经严格测试,关键电气参数满足多场景稳定工作需求:

  1. 阻值与精度:标称阻值75kΩ,精度±1%(实际阻值范围74250Ω~75750Ω),适合对偏差要求适中但需长期稳定的电路;
  2. 功率与功耗:25℃环境下额定功率100mW,温度升高需降额(如125℃时额定功率降至50mW);
  3. 工作电压:最大允许电压75V(由功率推导:$V=\sqrt{P×R}≈86.6V$,标注75V为降额设计,提升可靠性);
  4. 温度系数(TCR):±100ppm/℃,即温度每变1℃,阻值变化±0.01%。全温区(-55℃~+155℃)内阻值最大变化≤±1%,与精度要求一致。

三、封装与物理特性

采用0603封装(体积最小的贴片电阻规格之一),适配高密度布局:

  • 尺寸参数:长1.55±0.15mm,宽0.8±0.1mm,厚度0.45±0.1mm,重量约0.01g;
  • 结构设计:氧化铝陶瓷基板+钌基厚膜浆料(低TCR)+银钯合金电极(抗腐蚀)+玻璃釉保护层(绝缘防磨损);
  • 焊接兼容性:支持回流焊、波峰焊,电极拉脱力≥2N,满足批量生产可靠性。

四、环境适应性与可靠性

产品针对宽温与 harsh 环境优化,符合工业级标准:

  • 工作温度:-55℃~+155℃(覆盖工业、汽车电子场景);
  • 耐环境测试:
    • 耐湿性:85℃/85%RH下1000小时,阻值变化≤±1%;
    • 温度冲击:-55℃~+155℃循环500次,阻值变化≤±0.5%;
    • 机械振动:10g~2000Hz振动,阻值变化≤±0.3%;
  • 存储条件:-40℃~+60℃,湿度≤60%,开封后需尽快使用(避免受潮)。

五、典型应用场景

因小体积、宽温稳定、性价比高,广泛应用于:

  1. 消费电子:智能手机信号调理、智能穿戴低功耗电路;
  2. 工业控制:PLC反馈电阻、传感器信号放大、工业电源电压采样;
  3. 汽车电子:车载中控CAN总线匹配、仪表盘背光限流;
  4. 通信设备:基站射频匹配、路由器滤波、光纤收发器偏置电路;
  5. 医疗设备:小型医疗仪器(血糖仪、血压计)精密信号处理。

六、选型与使用注意事项

  1. 功率降额:环境温度>25℃时,需按信维官方降额曲线调整功率;
  2. 电压限制:严禁超过75V,避免过热击穿;
  3. 焊接工艺:回流焊峰值≤260℃(持续≤10s),波峰焊≤250℃(持续≤5s);
  4. 静电防护:HBM抗静电≥2kV,需在ESD防护区操作;
  5. 选型匹配:若需更高精度(±0.1%)或更低TCR(±50ppm/℃),需选薄膜电阻;更大功率(0.25W)需换0805封装。

SC0603F7502F2BNRH凭借高性价比、宽温稳定、小体积等优势,是工业与消费电子领域通用电阻的优选方案。

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
