UNI-ROYAL(厚声)0402WGF6490TCE 厚膜贴片电阻产品概述

UNI-ROYAL(厚声)推出的0402WGF6490TCE是一款专为小型化、高精度电路设计的厚膜贴片电阻,凭借紧凑的0402封装、稳定的电气性能及宽温适应性,广泛适配消费电子、工业控制等领域的高密度PCB设计需求。

一、产品基本信息

0402WGF6490TCE型号遵循电子元器件标准化命名逻辑:

  • 0402:英制封装规格(对应公制1005,尺寸约1.0mm×0.5mm),为目前最小的常规贴片电阻封装之一;
  • WGF:厚声针对小型化贴片电阻推出的系列标识,聚焦低功耗、高精度场景;
  • 6490:核心阻值参数(前三位为有效数字649,第四位0为倍率10⁰,即标称阻值649Ω);
  • TCE:精度与性能等级标识,对应±1%阻值精度;
  • 品牌:UNI-ROYAL(厚声),国内知名被动元件制造商,产品覆盖电阻、电容全系列。

二、核心技术参数详解

该电阻的关键参数直接决定应用边界,具体如下:

  1. 阻值与精度:标称阻值649Ω,精度±1%,实际阻值范围为642.51Ω~655.49Ω,满足分压网络、基准电路等对阻值一致性要求较高的场景;
  2. 功率与电压:额定功率62.5mW,最大工作电压50V,需注意实际功耗不超过额定值(P=V²/R,实际安全电压需结合应用场景控制);
  3. 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化0.01%;在-55℃~+155℃宽温范围内,阻值总变化量约±2.1%,结合±1%精度,总偏差控制在±3.1%以内;
  4. 工作温度范围:-55℃~+155℃,覆盖工业级宽温要求,可适应户外设备、汽车电子辅助电路等高低温场景。

三、封装与工艺特点

  1. 0402小型化封装:尺寸仅1.0mm×0.5mm,重量约0.005g,适配智能手机、智能穿戴、蓝牙耳机等高密度PCB设计,有效降低产品体积与重量;
  2. 厚膜电阻工艺:采用丝网印刷电阻浆料于陶瓷基底的厚膜技术,相比薄膜电阻成本更低、功率密度更高(62.5mW功率适配小型封装),且陶瓷基底耐温性能优异(可承受155℃长期工作),短时间可承受2倍额定功率过载。

四、典型应用场景

结合参数与封装优势,0402WGF6490TCE主要应用于:

  1. 消费电子:智能手机主板信号分压/限流电路、智能手表传感器接口匹配网络、蓝牙耳机射频匹配电阻;
  2. 工业控制:小型PLC I/O接口电路、传感器信号调理电路(如温度传感器分压基准);
  3. 通信设备:路由器/交换机小型电源电路(LED指示灯限流)、射频前端匹配网络;
  4. 汽车电子:车载中控辅助电路(按键背光限流)、低功耗传感器模块(胎压监测辅助电路)。

五、可靠性与环保特性

  1. 可靠性验证:通过高温存储(155℃×1000h)、温度循环(-55℃~+155℃×1000次)、回流焊耐热(260℃×3次)等测试,测试后阻值变化率≤0.5%,满足工业级可靠性要求;
  2. 环保合规:符合RoHS 2.0(无铅、无镉、无汞)、REACH等国际标准,适配全球绿色生产需求。

六、品牌与质量保障

UNI-ROYAL(厚声)拥有20余年被动元件生产经验,0402WGF6490TCE采用自动化生产与检测线,参数一致性好;批量采购支持定制化包装(10k/盘卷装、编带装),售后提供1年质量保障,技术支持响应及时。

该产品以高性价比、小型化优势,成为消费电子与工业领域高密度电路设计的优选电阻元件。

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
