0402WGF1213TCE 厚膜贴片电阻产品概述

一、产品核心定位

0402WGF1213TCE是UNI-ROYAL(厚声)推出的小封装高精度厚膜贴片电阻,针对小型化、高集成度电子设备设计,兼顾性能稳定性与成本控制,属于工业级基础被动元件。其核心特点为0402超小封装、±1%高精度、宽温工作范围,适配多种中低功率场景的电路需求,无需额外校准即可满足多数信号调理、分压等功能。

二、关键性能参数详解

1. 阻值与精度

标称阻值为121kΩ(阻值代码“1213”,即121×10³Ω),精度等级±1%,可满足多数电路对阻值一致性的要求。例如在分压电路中,该电阻与同精度电阻搭配时,输出电压偏差可控制在±1%以内,无需后续校准。

2. 功率与电压约束

  • 额定功率:62.5mW(等效1/16W),是0402封装电阻的典型功率值;
  • 最大工作电压:50V。需注意实际工作时需同时满足功率与电压限制(两者取较小值)——该电阻在50V下的实际功耗约20.7mW(50²/121000),远低于额定功率,因此电压限制为主要约束。

3. 温度系数(TCR)

温度系数为**±100ppm/℃**,即温度每变化1℃,阻值变化±12.1Ω(121kΩ×100e-6)。该指标可适应-55℃~+155℃的宽温环境,阻值漂移在工业级应用中可接受。

三、封装与物理特性

采用0402标准贴片封装,尺寸为1.0mm(长)×0.5mm(宽)×0.35mm(典型厚度),符合IPC-J-STD-001标准,具备以下优势:

  • 适配SMT自动贴装,生产效率高,适合大规模量产;
  • 超小体积可显著缩小电路模块尺寸,适配便携式设备(如智能手环、蓝牙耳机);
  • 焊盘设计符合行业规范,焊接可靠性高,无假焊、虚焊风险。

四、可靠性与环境适应性

1. 宽温工作能力

工作温度范围**-55℃~+155℃**,可覆盖汽车电子(发动机舱模块)、工业控制(户外传感器节点)等高低温场景,无需额外散热或温度补偿。

2. 厚膜工艺优势

采用厚膜印刷技术制造,电阻膜层稳定性优于薄膜电阻:

  • 抗浪涌能力强(典型浪涌承受能力为10倍额定功率/1ms);
  • 耐潮湿、耐机械振动(符合MIL-STD-202振动测试标准,振动频率20~2000Hz,加速度10g)。

3. 环保合规

符合RoHS 2.0、REACH等环保指令,焊端为无铅设计,适配绿色制造需求。

五、品牌与品质保障

UNI-ROYAL(厚声)是国内知名被动元件制造商,拥有20余年电阻生产经验,产品广泛应用于消费电子、汽车、工业等领域。0402WGF1213TCE通过以下品质管控:

  • 生产全流程检测:阻值分选(±0.5%以内批次一致性)、TCR筛选、功率老化测试;
  • 可靠性认证:通过AEC-Q200(汽车级)、IEC 60068(环境测试)等标准认证;
  • 售后支持:提供完整datasheet与可靠性报告,支持客户产品认证。

六、典型应用领域

  1. 便携式消费电子:蓝牙耳机、智能手环、智能手表的信号调理电路(如心率监测模块分压);
  2. 汽车电子:车载传感器(温度、压力传感器)的分压网络、ECU辅助电路;
  3. 工业控制:PLC输入输出模块、小型传感器节点的信号放大电路;
  4. 通信设备:小型基站、WiFi模块的射频前端偏置电路;
  5. 医疗电子:小型监护设备的低功耗电路(如血糖监测仪信号调理)。

该产品凭借小封装、高精度、宽温特性,成为中低端电子设备中替代进口电阻的高性价比选择,适用于对成本敏感且需稳定性能的场景。

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
