RMS04FT1913 厚膜贴片电阻产品概述

一、产品定位与核心特性

RMS04FT1913是大毅科技(Taiyo Yuden) 推出的0402封装厚膜贴片电阻,专为高密度、小体积电子设备的信号调理、电源管理等电路设计。其核心特性聚焦于高精度(±1%)、小封装适配、宽温环境稳定,平衡了性能与成本,是消费电子、工业控制等领域的通用型被动元件解决方案。

二、基础参数规格

该产品的关键参数均经过严格校准,满足电路设计的精准需求:

  • 电阻类型:厚膜贴片电阻(厚膜印刷工艺)
  • 标称阻值:191kΩ(阻值代码为“1913”,对应E24系列阻值规范:191×10³Ω)
  • 精度等级:±1%(阻值偏差控制在±1.91kΩ范围内)
  • 额定功率:62.5mW(0.0625W),适用于小功率电路负载
  • 最大工作电压:50V(直流/交流峰值电压,避免击穿风险)
  • 温度系数(TCR):±100ppm/℃(阻值随温度变化的漂移率)
  • 工作温度范围:-55℃至+155℃(覆盖工业级、汽车级部分环境需求)
  • 封装尺寸:0402(英制规格,公制对应1005,体积约1.0mm×0.5mm×0.4mm)
  • 环保认证:符合RoHS、REACH标准(无铅、无有害物质)

三、封装与工艺优势

3.1 小封装适配高密度布局

0402封装是当前电子设备中应用广泛的小尺寸封装之一,体积仅为1.0mm×0.5mm,可显著减少PCB占用面积,尤其适合智能手机、可穿戴设备等追求轻薄化的产品设计。

3.2 厚膜工艺的性能平衡

采用厚膜印刷技术制备电阻层,相比薄膜电阻成本更低,且耐过流能力更强;相比绕线电阻体积更小,阻值一致性更优,适合批量生产的精度控制。

3.3 无铅环保与可靠性设计

产品采用无铅电极,符合全球电子行业的绿色制造要求;电阻层与电极的结合工艺经过优化,降低了焊接时的接触电阻,提升长期可靠性。

四、典型应用场景

RMS04FT1913的参数特性使其适配多种电子设备的细分电路:

  • 消费电子:智能手机的电源管理IC(PMIC)反馈电阻、屏幕触控信号调理电路、无线耳机的蓝牙模块偏置电阻;
  • 工业控制:小型传感器(如温度、压力传感器)的信号放大电路、PLC(可编程逻辑控制器)的辅助分压电路;
  • 通信设备:基站射频前端的信号衰减电路、光纤收发器的电压基准电路;
  • 可穿戴设备:智能手表的心率传感器接口电阻、手环的低功耗信号处理电路。

五、可靠性与环境适应性

5.1 宽温下的阻值稳定性

±100ppm/℃的温度系数,在-55℃至+155℃的宽温范围内,阻值漂移控制在可接受区间(如25℃至125℃区间,阻值变化约±1910Ω,接近精度等级上限但仍满足多数电路需求),适合工业环境或极端温度场景。

5.2 功率与电压的安全裕量

62.5mW额定功率与50V最大工作电压,为电路设计提供了合理的安全裕量,避免因过载导致的电阻失效,提升系统整体可靠性。

5.3 长期可靠性测试

大毅科技对该产品进行了严格的可靠性验证,包括:高温老化(155℃×1000小时)、温度循环(-55℃~155℃×1000次)、湿度测试(85℃/85%RH×1000小时),测试后阻值变化率≤±0.5%,满足工业级产品的使用寿命要求。

六、品牌与品质保障

大毅科技作为全球被动元件领域的知名厂商,拥有数十年的厚膜电阻研发与生产经验,RMS04FT1913的品质管控贯穿全流程:

  • 原材料管控:电阻浆料、陶瓷基板均采用行业优质供应商,保证基础性能稳定;
  • 制程检测:每批次产品经过100%阻值测试、精度分选,确保出厂产品符合规格;
  • 认证体系:通过ISO9001质量管理体系、IATF16949汽车电子体系认证,部分批次可满足汽车级AEC-Q200标准(需定制)。

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
