0402WGF2211TCE 贴片厚膜电阻产品概述

一、产品基本信息

0402WGF2211TCE是厚声电子(UNI-ROYAL) 推出的一款0402封装贴片厚膜电阻,属于通用型高可靠性器件。型号中:

  • “0402”为英制封装尺寸(对应公制1.0mm×0.5mm),适配高密度PCB设计;
  • “2211”为阻值代码(前三位221为有效数字,第四位1为倍率,即221×10¹=2.21kΩ);
  • “WGF”为厚声电阻系列标识,“TCE”为具体参数后缀。

该产品采用厚膜工艺制造,兼顾小体积、高精度与环境适应性,广泛应用于消费电子、工业控制等领域。

二、核心技术参数

参数项 具体参数 说明 电阻类型 厚膜电阻 丝网印刷+烧结工艺,膜层附着力强 阻值 2.21kΩ(2210Ω) 符合信号调理、分压电路的常规需求 精度 ±1% 阻值偏差控制在合理范围,适配精度要求不苛刻的场景 额定功率 62.5mW 0402封装中功率密度较高,可承载中等负载 工作电压 50V(直流/交流峰值) 覆盖多数低压电路(3.3V~12V),避免过压损坏 温度系数(TCR) ±100ppm/℃ 温度每变化1℃,阻值波动约0.221Ω,温漂极小 工作温度范围 -55℃~+155℃ 满足工业级、汽车电子的极端环境需求

三、性能特点

1. 高精度与温漂控制

±1%的精度可满足信号放大、滤波电路的阻值匹配需求;±100ppm/℃的TCR保证了宽温环境下阻值稳定,尤其适合对信号一致性要求较高的场景(如传感器信号采集)。

2. 小体积高功率密度

0402封装尺寸紧凑(1.0mm×0.5mm),但额定功率达62.5mW,比同封装普通电阻的功率密度提升约20%,可有效节省PCB空间,适配智能手机、智能穿戴等高密度集成设备。

3. 宽温环境适应性

-55℃~+155℃的工作温度范围,能应对低温(北方户外设备)、高温(车载发动机舱附近)等极端环境,无需额外散热设计,降低电路复杂度。

4. 厚膜工艺可靠性

厚膜电阻的膜层与陶瓷基底结合牢固,抗机械冲击、耐老化性能优于薄膜电阻(部分场景),长期使用(>1000小时)阻值变化率<0.5%,适合工业设备的长期运行需求。

5. 电压兼容性强

50V额定工作电压覆盖了多数低压电路(3.3V、5V、12V系统),无需担心电压击穿风险,适用范围广。

四、典型应用场景

该电阻的性能适配多领域设计需求,常见应用包括:

  1. 消费电子:智能手机、平板电脑的音频放大、触控感应电路,利用小体积实现紧凑布局;
  2. 工业控制:PLC、温度传感器的信号放大电路,依靠±1%精度保证信号采集准确性;
  3. 汽车电子:车载仪表盘、倒车雷达的辅助电路,适应-40℃~+85℃的车载环境;
  4. 通信设备:路由器、交换机的射频匹配电路,小体积适配高密度PCB;
  5. 医疗设备:小型监护仪、血糖仪的信号处理电路,厚膜工艺保证长期稳定运行。

五、品牌与封装优势

1. 厚声电子(UNI-ROYAL)优势

作为国内电阻制造龙头企业,厚声电子拥有20余年厚膜电阻生产经验,产品通过ISO9001、IATF16949等国际认证,供货稳定,品质符合汽车电子、工业级标准。

2. 0402封装优势

0402封装是电子设备中应用最广泛的小封装之一,贴装效率高(高速贴片机每小时可贴装数万件),且与Altium、Cadence等主流PCB设计软件兼容,降低设计与生产难度。

总结

0402WGF2211TCE贴片厚膜电阻凭借高精度、小体积、宽温适应性与可靠性能,成为消费电子、工业控制、汽车电子等领域的优选器件,适配多种电路设计需求,是平衡性能与成本的理想选择。

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
