SC0402F7501F2ANRH 厚膜贴片电阻产品概述

一、产品定位与核心属性

SC0402F7501F2ANRH是信维通信(Sunway)推出的0402封装厚膜贴片电阻,针对小型化、高精度电子设备设计,属于低功率高精度被动元件范畴。其核心定位是满足消费电子、工业控制、汽车电子等领域的小信号电路需求,兼顾体积、精度与成本优势。

二、核心电气参数全解析

该电阻的关键参数直接决定应用场景,具体如下:

  1. 阻值与精度:标称阻值7.5kΩ(型号中“7501”对应7500Ω),精度±1%——实际阻值偏差范围为7425Ω~7575Ω,能精准满足信号调理、分压、限流等对阻值一致性要求较高的电路;
  2. 功率与电压:额定功率62.5mW,工作电压50V——适配低功耗电路(如传感器节点、小型MCU周边),避免过功率/过电压损坏,同时满足一般模拟电路的电压需求;
  3. 温度特性:温度系数±100ppm/℃,工作温度范围-55℃~+155℃——温度每变化1℃,阻值变化≤0.01%,宽温范围覆盖工业级高低温环境,甚至可满足汽车电子部分高温场景(如舱内局部高温);
  4. 封装尺寸:0402英制封装(公制1005,尺寸约1.0mm×0.5mm)——体积小巧,适合高密度PCB贴装,可显著降低设备整体尺寸,适配可穿戴、智能手机等小型化产品。

三、制造工艺与可靠性保障

该电阻采用厚膜电阻工艺:通过在高稳定性陶瓷基底上印刷电阻浆料、高温烧结成型,再进行电极制作与封装,兼具以下优势:

  • 相比薄膜电阻成本更低,适合批量应用;
  • 相比绕线电阻体积更小、耐温性更好,适配贴片自动化生产;
  • 信维通信对产品进行多环节可靠性测试,包括:
    ① 高低温循环测试(-55℃~155℃循环100次,阻值变化≤0.5%);
    ② 湿度测试(85℃/85%RH环境下1000小时,性能无衰减);
    ③ 耐电压测试(50V额定电压下无击穿、漏电流≤1μA),确保恶劣环境下性能稳定。

四、典型应用场景

结合参数特性,该电阻广泛应用于以下场景:

  1. 可穿戴设备:智能手环/手表的传感器信号调理电路(如心率传感器分压、加速度计限流);
  2. 智能手机:音频模块滤波电路、电源管理单元(PMU)辅助限流电阻;
  3. 工业控制:小型传感器节点(温度/压力传感器)的信号放大前置电路;
  4. 汽车电子:低功耗辅助电路(如胎压监测系统(TPMS)信号处理电路,适配汽车舱内高温环境);
  5. 消费电子:蓝牙耳机、智能音箱的小信号放大电路、按键电路限流。

五、品牌与市场适配性

信维通信作为国内射频与被动元件领域龙头企业,具备完善的供应链体系与技术研发能力:

  • 产品符合IEC 61000-4系列电磁兼容标准、JIS C 5201电阻器行业标准;
  • 可支持客户定制化需求(如特殊封装、阻值微调);
  • 适合对体积、精度、成本有综合要求的电子设备厂商,尤其适配中小批量到大规模量产场景。

该产品凭借“小体积+高精度+宽温适应性”的组合优势,成为消费电子与工业领域小型化电路的优选被动元件之一。

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
