MBA02040C1001FCT00 产品概述

一、产品简介

MBA02040C1001FCT00 是 VISHAY(威世)品牌的一款金属膜插件电阻,标准轴向结构、尺寸为 Ø1.6 × 3.6 mm,额定功率 0.4 W,阻值 1 kΩ,公差 ±1%。该器件以金属膜材料为电阻体,兼顾低噪声、良好频率特性与优越的稳定性,适用于对精度和温漂有较高要求的通用电子电路中。

二、主要技术参数

  • 电阻类型:金属膜电阻(Metal Film)
  • 封装形式:插件(THT),D1.6 × L3.6 mm
  • 标称阻值:1 kΩ(1000 Ω)
  • 精度:±1%
  • 额定功率:0.4 W(常温条件下)
  • 温度系数:±50 ppm/℃(非常低的温度漂移)
  • 工作温度范围:-55 ℃ 至 +155 ℃
  • 外形尺寸(典型):直径 1.6 mm,体长 3.6 mm
  • 品牌:VISHAY(威世)

(注:以上为典型参数摘要,具体电气和机械规范请以厂商出具的完整数据手册为准。)

三、关键特性与优势

  • 精度高:±1% 公差满足多数精密分压、偏置及滤波网络的需求。
  • 低温漂:±50 ppm/℃ 的温度系数保证在广泛温度变化下阻值稳定,适合温度敏感的测量与控制电路。
  • 低噪声与良好频率响应:金属膜工艺使器件在音频及高频应用中具有较低的热噪声和较好的频率特性。
  • 抗环境能力强:宽温度范围(-55 ℃ 至 +155 ℃)适合工业级和户外电源/传感场景。
  • 插件形式便于焊接与维修:适合手工装配或波峰/选择性回流焊后插件工艺的混合装配。

四、典型应用场景

  • 精密模拟电路:运算放大器偏置、反馈网络、增益设定等场合。
  • 测量与传感器接口:对温漂与稳定性有要求的分压和参考电路。
  • 工业控制与仪表:长期稳定性和耐高温特性满足工业环境需求。
  • 音频电路:由于金属膜低噪声特性,可用于高保真音频放大器中的精密元件。
  • PCB 原型与维修:THT 形式便于快速替换与手工焊接。

五、安装与使用建议

  • 焊接温度:遵循常规插件元件的焊接规范,避免长时间高温直接作用于电阻本体,必要时采用适当的散热措施或控制焊接时间。
  • 功率降额:在高环境温度下,建议根据系统温升对额定功率进行降额处理,确保电阻工作在安全温度范围内。常见做法是在超过 70 ℃ 时逐步进行降额以延长寿命。
  • 机械应力:避免在焊接或装配过程中对电阻体施加过大的弯曲力或拉力,以防引起内部结构损伤或引线疲劳。
  • 储存与清洁:避免潮湿和腐蚀性气体环境,焊前如需清洗请使用对金属膜电阻安全的清洗剂并充分干燥。

六、可靠性与环境适应性

该系列金属膜电阻设计用于长期稳定运行,具有良好的温度循环与长期漂移特性。工作温度范围跨越工业级标准(-55 ℃ 至 +155 ℃),适合严酷环境下的可靠工作。对于具体的寿命、温度循环、湿热与冲击振动测试结果,请参考 VISHAY 的产品认证与完整可靠性报告。

七、订购与包装信息

  • 品牌:VISHAY(威世)
  • 产品型号示例:MBA02040C1001FCT00(用于识别 1 kΩ、0.4 W、±1% 金属膜插件电阻)
  • 包装形式:常见为卷装或小盘包装用于插件装配,具体包装单位与材料请以厂商销售手册为准。
  • 采购建议:量产前建议索取样品及数据手册并确认批次一致性;涉及法规合规(如 RoHS、REACH 等)或特定认证需求时,请在订单中明确要求或咨询当地代理。

八、常见问题与注意事项

  • 是否耐高浪涌电流:作为低功率金属膜电阻,其脉冲耐受能力有限,需在电路设计中避免长期或重复的大电流冲击。
  • 是否有更高功率/不同精度的对应产品:VISHAY 系列中有不同功率、不同体型与公差等级的金属膜电阻,可以根据功率与精度需求选择相邻型号。
  • 获取数据手册:为确保设计和可靠性评估,请从 VISHAY 官方或授权分销商获取最新数据表与可靠性试验报告。

如需完整数据手册、温度功率降额曲线或样品支持,建议直接联系 VISHAY 当地代理或访问 VISHAY 官方网站获取最准确的技术资料与认证信息。

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
