0402WGJ020JTCE 贴片厚膜电阻产品概述

一、产品基本定位与核心身份

0402WGJ020JTCE是UNI-ROYAL(厚声) 推出的0402封装厚膜贴片电阻,属于小功率通用型电阻,核心参数明确对应:阻值2Ω、精度±5%、额定功率62.5mW,专为小型化电子电路设计,兼顾成本与稳定性。

二、核心电气参数详解

该型号的电气性能围绕“小封装适配小信号”的设计目标展开,关键参数需重点关注:

  1. 阻值与精度:固定阻值2Ω,精度±5%——符合厚膜电阻的常规精度等级,能满足多数非超高精度电路需求(如电流采样、分压滤波等);
  2. 额定功率:62.5mW(0.0625W)——适配0402封装的典型功率上限,实际工作需注意功率降额(如125℃环境下需降至额定功率的50%使用);
  3. 工作电压:最大50V——需结合功率约束(实际工作电压不应超过√(P×R)≈0.35V),避免因电压过高导致功率超额定值;
  4. 温度系数(TCR):±400ppm/℃——表示温度每变化1℃,阻值变化±0.04%;在-55℃~+155℃宽温范围内,阻值最大漂移约±4%,满足工业级环境稳定性要求。

三、封装与工艺特性

3.1 封装规格

采用0402封装(英制:0.04英寸×0.02英寸;公制1005:长1.0mm×宽0.5mm),是贴片电阻最小的常规封装之一,适配高密度PCB设计(如智能手机、可穿戴设备等)。

3.2 厚膜工艺优势

基于丝网印刷+高温烧结工艺制造,核心特点:

  • 成本低于薄膜电阻,性价比突出;
  • 抗脉冲能力优于薄膜电阻(适合小信号脉冲电路);
  • 阻值覆盖广(毫欧级至兆欧级),本型号2Ω为小阻值典型值。

四、环境适应性与可靠性

  1. 宽温工作范围:-55℃+155℃——覆盖工业级(-40℃+85℃)和汽车级(-55℃~+125℃)部分场景,能适应极端温度环境;
  2. 可靠性测试:通过高温老化(155℃/1000h)、湿度循环(85℃/85%RH)、温度冲击(-55℃~+155℃循环)等测试,阻值漂移率≤1%;
  3. 环保合规:符合RoHS 2.0、REACH标准,不含铅、镉等有害物质。

五、典型应用场景

该型号因“小封装+小阻值+低功耗”的组合,适用于以下场景:

  1. 小电流采样:如蓝牙耳机、智能手环的电池充放电电流检测(采样电流≤177mA,符合功率要求);
  2. 小信号处理:音频前置放大电路的RC滤波、传感器信号调理的分压网络;
  3. 高密度电路:智能手机主板、智能手表、IoT模块等小型化设计;
  4. 工业控制:PLC输入输出模块的限流电阻、传感器信号隔离电路。

六、品牌与品质保障

UNI-ROYAL(厚声)拥有20+年电阻制造经验,0402系列产品优势:

  • 产能稳定,批量供货周期短(1-2周);
  • 品质管控严格,每批次通过阻值分选、外观检测;
  • 广泛应用于消费电子、工业控制、汽车电子领域,客户认可度高。

该型号是小型化电子电路中“小阻值、低功耗”需求的高性价比选择,适配多数常规电路场景。

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
