VISHAY MBB02070C1504FCT00 金属膜插件电阻产品概述

一、产品定位与品牌背景

VISHAY(威世)作为全球无源电子元器件领域的领军厂商,其MBB系列金属膜电阻以高精度、宽温稳定、中等功率适配为核心设计目标。MBB02070C1504FCT00是该系列中针对1.5MΩ阻值的细分型号,主要面向工业控制、仪器仪表、通信等对阻值精度和温漂要求较高的应用场景,弥补了常规碳膜电阻精度不足、温漂过大的短板,同时兼顾插件封装的焊接可靠性。

二、关键技术参数深度解析

(一)阻值与精度

型号中“1504”为阻值编码(15×10⁴=1.5MΩ),精度标注为**±1%**,远高于普通碳膜电阻(±5%),可满足信号调理、分压电路等对阻值一致性要求较高的设计需求,减少电路误差累积。

(二)功率与负载能力

额定功率为600mW(0.6W),属于中等功率金属膜电阻,覆盖大部分常规电路的功率需求(如电源分压、滤波、小信号放大负载等)。需注意:高温环境下需参考VISHAY降额曲线使用,避免超过最大允许功耗。

(三)温度系数(TCR)

温度系数为**±50ppm/℃**,表示温度每变化1℃,阻值变化±50×10⁻⁶。例如,当环境温度从-55℃升至+155℃(温差210℃),阻值最大漂移约15.75kΩ,远低于低精度电阻的漂移量,确保宽温环境下电路性能稳定。

(四)工作温度范围

支持**-55℃至+155℃**的宽温工作,覆盖工业级(通常-40~125℃)、部分高温工业场景(如锅炉控制、汽车发动机舱周边),适应极端环境下的长期可靠运行。

三、封装与物理特性

采用插件式封装,外形尺寸为直径2.5mm×长度6.5mm,引脚间距符合标准PCB焊盘设计,适合手工焊接、波峰焊等传统工艺;体积紧凑,可在空间有限的电路板上高密度布局,同时插件式引脚的机械强度高于贴片电阻,适合对焊接可靠性要求较高的场合。

四、核心性能优势

  1. 高精度低漂移:±1%精度+±50ppm/℃温漂,确保电路在全温区阻值稳定;
  2. 宽温可靠:-55~155℃工作范围,适配极端环境应用;
  3. 品牌可靠性:VISHAY成熟的金属膜工艺,产品一致性好,长期使用故障率低;
  4. 功率适配性:600mW额定功率覆盖多数常规电路需求,无需额外并联电阻提升功率。

五、典型应用场景

  1. 工业控制电路:传感器信号调理(压力、温度传感器分压)、PLC输入输出接口;
  2. 仪器仪表:万用表、示波器的分压网络、高精度信号源校准电路;
  3. 通信设备:基站电源滤波、射频接口匹配电阻;
  4. 汽车电子:高温模块(发动机控制单元周边)的辅助电路;
  5. 医疗设备:监护仪、输液泵的低漂移信号电路。

六、使用注意事项

  1. 降额使用:环境温度超过70℃时,需按VISHAY datasheet降额(如125℃时最大允许功耗约300mW);
  2. 焊接要求:手工焊接温度≤260℃,时间≤3秒;波峰焊温度≤250℃,时间≤5秒;
  3. 存储条件:未焊接产品存放在常温(15~35℃)、干燥(相对湿度≤60%)环境,避免受潮氧化。

该型号凭借VISHAY的工艺优势与宽温稳定特性,成为高精度中等功率电路设计的可靠选择。

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
