RTT031403FTP 厚膜贴片电阻产品概述

RTT031403FTP是旺诠(RALEC) 推出的一款通用型厚膜贴片电阻,采用0603(英制)/1608(公制)封装,针对中低功率、高精度需求的电子电路设计,广泛覆盖消费电子、工业控制等多领域应用。

一、产品基本属性

该电阻属于旺诠厚膜贴片电阻系列,核心定位为常规精度(±1%)、小功率(100mW) 的通用元件,型号命名逻辑清晰:

  • RTT:旺诠厚膜贴片电阻系列代号;
  • 0314:封装代码(对应0603标准贴片封装);
  • 03FTP:参数代码(明确140kΩ阻值、±1%精度)。

二、核心电气参数

RTT031403FTP的关键指标匹配多数电子电路的基础需求,具体如下:

  1. 阻值与精度:额定阻值140kΩ,精度±1%(实际阻值范围138.6kΩ~141.4kΩ),可满足信号调理、分压电路等对阻值准确性要求不极端的场景;
  2. 功率与电压:额定功率100mW(0.1W),最大工作电压75V,需注意电压与功率的匹配(如75V工作电压下,最大允许电流约1mA,符合欧姆定律);
  3. 温度系数:±100ppm/℃,表示温度每变化1℃,阻值变化±140kΩ×100×10⁻⁶=±14Ω;在-55℃~+155℃温区内,阻值最大漂移约±1.4kΩ,可接受多数应用的温漂影响。

三、封装与物理特性

采用0603贴片封装(公制尺寸约1.6mm×0.8mm×0.4mm),是贴片电阻中常见的小尺寸封装,具备以下特点:

  • 适配SMT自动化生产:无引脚设计可减少焊接点寄生参数,提升电路高频性能(适用于100MHz以下低频/中频电路);
  • 厚膜工艺制造:通过丝网印刷电阻浆料于陶瓷基底,经烧结形成电阻层,成本低且稳定性好,适合大规模量产;
  • 尺寸紧凑:可有效缩小电子设备的PCB面积,满足小型化设计需求。

四、环境适应性

该电阻的环境耐受能力覆盖工业级温区,满足复杂场景需求:

  • 工作温度范围:-55℃~+155℃,可应对低温(如车载启动时-40℃以下环境)和高温(如工业控制柜内125℃环境);
  • 耐温稳定性:陶瓷基底具备良好热稳定性,极端温度下阻值漂移可控,符合IEC 61000等环境测试标准。

五、典型应用场景

结合参数与特性,RTT031403FTP适用于以下场景:

  1. 消费电子:手机、平板、智能穿戴的信号放大电路、分压电路(如电池电量检测、音频信号调理);
  2. 工业控制:传感器信号采集(温度/压力传感器放大)、PLC输入输出接口;
  3. 车载电子:车载导航、仪表盘低功率电路(满足-40℃~+85℃车载温区);
  4. 通信设备:路由器、交换机的电源偏置电路、信号滤波电路(小功率、高精度需求)。

六、品牌与可靠性说明

旺诠(RALEC)作为台湾知名被动元件制造商,产品具备以下优势:

  • 环保合规:符合RoHS 2.0、REACH标准,无铅焊接兼容;
  • 批量一致性:厚膜工艺制程控制严格,同一批次电阻参数偏差小;
  • 可靠性验证:通过高温存储、温度循环、湿热等测试,使用寿命可达5年以上。

总结:RTT031403FTP是一款高性价比厚膜贴片电阻,以0603小封装、±1%精度、宽温区为核心优势,适用于多领域常规电子电路设计,是工业控制、消费电子等场景的常用元件。

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
