SC0402J1004F2ANRH 贴片电阻产品概述

一、产品基本属性

SC0402J1004F2ANRH是Sunway(信维通信) 推出的一款厚膜贴片电阻,属于小型化表面贴装被动元件。该产品通过4位编码明确核心参数(1004表示标称阻值1MΩ),封装规格为0402,适用于各类电子电路的阻抗匹配、分压、限流等基础功能,是消费电子、工业控制等领域的通用型电阻元件。

二、关键性能参数详解

1. 阻值与精度

  • 标称阻值:1MΩ(由4位编码“1004”定义:前三位“100”为有效数字,第四位“4”表示×10⁴,即100×10⁴=1,000,000Ω);
  • 精度等级:±5%(代码“J”),满足多数通用电路对阻值偏差的要求,无需高精度场景下可有效控制成本。

2. 功率与电压

  • 额定功率:62.5mW(0.0625W),是电阻长期稳定工作的最大功率上限;
  • 最大工作电压:50V,实际应用中需同时满足“电压≤50V”和“功率≤62.5mW”,避免过压或过功率导致元件损坏(若仅按功率计算,极限电压为√(62.5e-3×1e6)=250V,但实际需以50V为约束)。

3. 温度系数

  • 温度系数:±100ppm/℃,表示温度每变化1℃,阻值变化量为标称阻值的±100×10⁻⁶。例如:25℃到125℃(温差100℃)时,阻值变化为1e6×100×10⁻⁶×100=100Ω,即阻值范围为99900Ω~100100Ω,稳定性满足一般温度环境需求。

4. 工作温度范围

  • 范围:-55℃~+155℃,覆盖工业级、汽车级(部分场景)的温度要求,可在极端环境下(如沙漠高温、高原低温)稳定工作。

三、封装与尺寸规格

采用0402封装(英制尺寸:0.04英寸×0.02英寸;公制尺寸:1.0mm×0.5mm),厚度约0.3mm(典型值),引脚间距约0.3mm。该封装适配各类小型化PCB设计,支持自动贴装(SMT)工艺,生产效率高,适合批量生产,可满足智能手机、智能穿戴等紧凑型设备的空间需求。

四、典型应用场景

该电阻因高阻值、小封装、宽温特性,广泛应用于以下领域:

  1. 消费电子:智能手机、平板电脑、智能手表的射频信号调理(如滤波器、匹配网络)、低功耗传感器接口(如压力/温度传感器分压电路);
  2. 工业控制:PLC模拟量输入输出接口、电机驱动电路限流保护、工业传感器信号放大电路;
  3. 汽车电子:车载信息娱乐系统音频接口、胎压监测(TPMS)信号调理、辅助驾驶传感器电路(宽温范围可覆盖部分汽车场景);
  4. 医疗设备:便携式血糖仪、血压计的低功耗电路、医疗传感器信号滤波;
  5. 通信设备:路由器、交换机电源滤波、射频前端阻抗匹配网络。

五、可靠性与环境适应性

  1. 工艺可靠性:采用厚膜电阻工艺(丝网印刷+烧结),电阻膜层均匀、附着力强,抗机械应力(如振动、跌落)和电应力(如浪涌)能力优于部分薄膜电阻,长期阻值漂移小;
  2. 环境验证:经高低温循环(-55℃155℃)、湿度测试(85℃/85%RH)、振动测试(102000Hz)等验证,符合IEC 61000系列标准;
  3. 长期稳定性:额定条件下阻值漂移率≤0.5%/1000小时(典型值),可满足产品5年以上使用寿命需求。

六、品牌与品质保障

Sunway(信维通信)是国内射频与被动元件龙头企业,专注电子元器件研发生产超20年,产品服务华为、苹果、三星等全球客户。SC0402J1004F2ANRH通过ISO 9001质量管理体系认证,多数批次符合RoHS环保标准,可满足绿色电子产品生产要求,品质稳定可靠。

该产品凭借高性价比、宽温特性和小封装优势,成为通用电子电路中1MΩ高阻应用的优选元件。

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
