0402WGF2802TCE厚膜贴片电阻产品概述

一、产品核心参数概览

0402WGF2802TCE是厚声(UNI-ROYAL)推出的0402封装厚膜贴片电阻,核心参数精准匹配小功率、高精度电路需求,具体如下:

  • 电阻类型:厚膜电阻(厚膜工艺制备,性能稳定、成本可控)
  • 标称阻值:28kΩ(阻值编码为“2802”,符合贴片电阻编码规则:前两位为有效数字,第三位为10的幂次)
  • 精度等级:±1%(满足大多数精密电路对阻值偏差的要求,无需额外校准)
  • 额定功率:62.5mW(典型小功率应用场景,如信号调理、低功耗电路)
  • 最大工作电压:50V(适用于低压直流/交流电路,安全裕量充足)
  • 温度系数(TCR):±100ppm/℃(温度变化时阻值漂移极小,宽温环境下性能稳定)
  • 工作温度范围:-55℃~+155℃(覆盖工业级宽温需求,适应极端环境)
  • 封装规格:0402(英制尺寸:0.04″×0.02″,公制尺寸:1.0mm×0.5mm)

二、关键性能特性解析

  1. 高精度与低漂移:±1%的精度等级确保电路信号传输、分压等功能的一致性;±100ppm/℃的温度系数使阻值在-55℃至155℃范围内,最大漂移量仅为5.88Ω(计算:28kΩ×100ppm/℃×210℃=28000×0.0001×210=5.88Ω),适合精密测量电路。
  2. 小功率与高适配性:62.5mW额定功率针对低功耗电路设计,同时50V最大工作电压满足常见低压电路需求,避免过压损坏风险。
  3. 宽温可靠性:-55℃至+155℃的工作温度范围,覆盖工业环境(如户外传感器、车载辅助电路)、消费电子(如智能手机高温环境)的极端温度场景,无需额外散热设计。

三、封装与物理特性说明

0402封装是目前贴片电阻中超小型封装之一,具备三大优势:

  • 体积紧凑:1.0mm×0.5mm的尺寸大幅节省PCB布局空间,适合高密度集成设计(如可穿戴设备、小型化模块);
  • 贴装兼容性:完全适配SMT自动贴装工艺,生产效率高,适合大规模量产;
  • 机械稳定性:厚膜电阻结构坚固,抗振动、抗冲击性能满足工业和消费电子的可靠性要求。

四、典型应用场景

0402WGF2802TCE凭借小体积、高精度、宽温特性,广泛应用于以下领域:

  1. 消费电子:智能手机、平板电脑的电源管理模块(如DC-DC转换电路反馈电阻)、音频放大偏置电阻;
  2. 可穿戴设备:智能手表、手环的传感器接口(如心率传感器分压电阻)、低功耗蓝牙模块匹配电阻;
  3. 工业控制:小型传感器节点(如温度/压力传感器信号放大电阻)、PLC辅助逻辑电路;
  4. 通信设备:小型基站、路由器的射频前端辅助电路(如滤波器匹配电阻)、光纤收发器偏置电阻;
  5. 汽车电子(辅助级):车载信息娱乐系统背光驱动分压电阻、车身传感器信号调理电路(满足-40℃至125℃的基础汽车级需求)。

五、品牌与可靠性优势

厚声(UNI-ROYAL)作为全球知名电子元器件制造商,0402WGF2802TCE具备以下可靠性优势:

  • 成熟工艺:采用高精度厚膜印刷技术,阻值一致性好,批量生产偏差控制严格;
  • 环保合规:符合RoHS、REACH等国际环保标准,无铅无镉,适配绿色制造需求;
  • 可靠性测试:通过高温老化、湿度循环、振动冲击等多项测试,满足IEC、JIS等行业标准;
  • 量产能力:大规模生产能力强,供货周期短,适合客户量产需求。

该产品平衡了性能、体积与成本,是小功率精密电路的理想选择。

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
