RTT02682JTH厚膜贴片电阻产品概述

RTT02682JTH是台湾旺诠(RALEC)推出的0402封装通用型厚膜贴片电阻,针对小型化、低功耗、宽温适应性场景设计,兼顾成本与性能,广泛适配消费电子、工业控制等领域的高密度电路需求。

一、核心身份与定位

该产品属于旺诠电阻产品线中的常规精度厚膜贴片电阻,聚焦“小体积+高可靠+宽温适配”三大核心,填补了0402封装下高功率密度(相对同封装)、宽温范围的市场需求,是替代传统插件电阻或低规格贴片电阻的优选方案之一。

二、关键性能参数详解

RTT02682JTH的核心参数围绕“小型化电路的实用需求”设计,关键指标如下:

  • 阻值与精度:标称阻值6.8kΩ(代码“682”,即68×10²Ω),精度±5%——满足多数电路的分压、限流、信号调理等基本精度要求,无需额外校准;
  • 功率等级:额定功率62.5mW(0.0625W)——适配低功耗电路(如智能穿戴、传感器节点),实际使用中建议降额30%以上,确保长期可靠性;
  • 工作电压:最大直流/交流耐压50V——满足一般低压电路的绝缘要求,避免过压击穿;
  • 温度系数(TCR):±100ppm/℃——表示温度每变化1℃,阻值变化±100×10⁻⁶,即100℃温变下阻值变化±1%,适合温变范围不极端的场景;
  • 工作温度范围:-55℃+155℃——覆盖工业级(-4085℃)及部分汽车级(-40~125℃)场景,可应对高低温交替的严苛环境。

三、封装与工艺特性

  • 封装规格:0402(英制代码,对应公制1005),尺寸为1.0mm×0.5mm×0.4mm(长×宽×高)——体积仅为传统0805封装的1/4,适配高密度PCB设计(如手机主板、小型通信模块);
  • 厚膜工艺:采用陶瓷基片+印刷电阻浆料+烧结工艺——相比薄膜电阻成本更低,相比线绕电阻更适合贴片封装,兼具“稳定性好、抗冲击振动、功率密度适中”的特点;
  • 引脚与焊接:端电极采用镍/锡镀层,兼容回流焊、波峰焊工艺,焊接可靠性符合IPC-A-610标准。

四、典型应用场景

RTT02682JTH的参数特性决定了其适用场景集中在小型化、低功耗、宽温需求的领域:

  1. 消费电子:智能手机、平板、智能手表的信号滤波、分压电路,蓝牙模块的偏置电阻;
  2. 工业控制:小型PLC的I/O接口电阻、传感器节点的限流电阻,LED指示灯驱动电路;
  3. 汽车电子:车载USB充电模块、仪表盘辅助电路(非安全关键件),满足-40~125℃的常规汽车环境;
  4. 通信设备:小型基站、路由器的电源滤波电阻,WiFi模块的匹配网络电阻。

五、可靠性与环境适应性

旺诠对该产品的可靠性管控符合IEC 61000、MIL-STD-202等标准,关键可靠性指标包括:

  • 抗振动:可承受10~2000Hz、1.5g的振动测试,适配运输及动态使用场景;
  • 耐温湿度:在85℃/85%RH环境下连续工作1000小时,阻值变化率≤1%;
  • 寿命:在额定功率下工作,MTBF(平均无故障时间)≥10⁶小时,满足长期使用需求。

六、品牌与质量背书

RALEC旺诠是全球知名的被动元件制造商,专注电阻、电容等产品研发30余年,产品覆盖消费、工业、汽车等领域。RTT02682JTH符合RoHS 2.0、REACH等环保标准,无铅无卤,可满足欧盟、北美等市场的合规要求,广泛应用于华为、小米、富士康等客户的终端产品中。

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
