RMS04FT4700 厚膜贴片电阻产品概述

一、产品基本信息

RMS04FT4700是大毅科技推出的一款精密厚膜贴片电阻,型号命名遵循行业通用规则:

  • 系列标识:“RMS”为大毅厚膜贴片电阻核心系列;
  • 封装规格:“04”对应0402英制封装(公制尺寸约1.0mm×0.5mm);
  • 精度等级:“F”代表阻值精度±1%;
  • 阻值代码:“4700”即470Ω(后两位“00”表示10⁰倍)。

该产品定位为小体积高可靠电阻,适配空间紧凑、精度要求较高的电子电路场景。

二、核心参数详解

1. 阻值与精度

阻值为470Ω,精度±1%,满足多数电子电路的精密控制需求(如信号分压、偏置电路等),无需额外校准即可实现稳定输出。

2. 功率与电压约束

  • 额定功率:62.5mW(0402封装典型额定功率,实际工作功率需低于此值);
  • 最大工作电压:50V(需注意:电压与电流的乘积不得超过额定功率,即最大电流≈50V/470Ω≈106mA,需同时满足功率限制)。

3. 温度特性

  • 温度系数(TCR):±100ppm/℃,表示每升高1℃,阻值变化约0.01%;
  • 工作温度范围:-55℃~+155℃,覆盖工业级、汽车级(部分场景)的极端温度需求,宽温范围内总阻值变化≈2.1%(温差210℃×100ppm),叠加±1%精度后仍满足多数应用。

三、封装与物理特性

RMS04FT4700采用0402表面贴装封装,物理特性如下:

  • 尺寸:长1.0mm×宽0.5mm×厚0.3mm(公制),体积仅为常规插件电阻的1/10;
  • 基底材料:高纯度氧化铝陶瓷,确保热稳定性与机械强度;
  • 电阻层:钌系厚膜电阻浆料,性能稳定、老化率低;
  • 电极:无铅锡/镍电极,符合RoHS、REACH环保标准,焊接可靠性高;
  • 贴装适配:支持自动化SMT生产线,生产效率与一致性高。

四、性能优势

  1. 小体积高密度:0402封装可大幅提升PCB布局密度,适配智能手机、可穿戴设备等小型化产品;
  2. 高精密稳定:±1%精度与±100ppm/℃ TCR,长期工作中阻值漂移≤0.5%(1000小时老化测试);
  3. 宽温适应性:-55℃~+155℃工作范围,可应用于户外设备、汽车电子等极端环境;
  4. 可靠性优异:通过JESD22振动测试(10-2000Hz、2g加速度)、温度循环测试(-55~155℃循环1000次),无开路/短路故障;
  5. 成本可控:厚膜工艺兼顾性能与成本,适合中大规模量产应用。

五、典型应用场景

RMS04FT4700因特性适配性强,广泛应用于:

  1. 消费电子:智能手机电源管理(分压、限流)、平板电脑信号调理模块;
  2. 工业控制:小型PLC传感器接口、模拟信号滤波电路;
  3. 汽车电子:车载中控屏按键电路、低功率胎压监测模块;
  4. 通信设备:小型基站射频前端偏置电路、路由器信号衰减网络;
  5. 物联网:低功耗温湿度传感器节点、智能家居控制电路。

六、品牌与质量保障

大毅科技是全球被动元器件领域知名厂商,拥有30+年研发生产经验,产品通过ISO 9001(通用质量)、IATF 16949(汽车级)认证。RMS04FT4700生产过程采用SPC统计过程控制,每批次产品参数一致性≥99.5%,可满足客户长期稳定供货需求。

该产品以“小体积、高精密、宽温可靠”为核心竞争力,是电子设备小型化、高集成度设计的优选电阻方案。

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
