0402WGF1401TCE 厚膜贴片电阻产品概述

一、产品基本定位与身份

0402WGF1401TCE是厚声电子(UNI-ROYAL) 推出的一款0402封装厚膜贴片电阻,属于小功率精密电阻范畴。型号中:

  • “0402”对应英制封装尺寸(公制1005,实际尺寸约1.0mm×0.5mm×0.3mm);
  • “WGF”为厚声厚膜电阻系列标识;
  • “1401”代表阻值(14×10¹=1400Ω=1.4kΩ);
  • “TCE”为具体规格代码(含精度、温度系数等参数)。

该产品针对小型化、高密度电路设计,兼顾成本与性能稳定性,广泛适配消费电子、工业控制等领域的中小功率应用场景。

二、核心参数详细说明

0402WGF1401TCE的参数精准覆盖多数中小功率精密需求:

  • 阻值与精度:标称1.4kΩ,精度±1%——满足分压、限流、偏置等电路的一致性要求,相比±5%常规电阻,可减少调试复杂度;
  • 功率与电压:额定功率62.5mW(0.0625W),额定电压50V。实际应用需遵循降额原则:如125℃环境下,功率需降额至额定值的50%,避免过热失效;
  • 温度特性:温度系数(TCR)±100ppm/℃——温度每变化1℃,阻值变化±0.014Ω(1.4kΩ×100×10⁻⁶);工作温区-55℃~+155℃,覆盖工业级极端环境;
  • 封装与尺寸:0402封装体积小巧,可有效节省PCB空间,适配智能手机、可穿戴设备等对尺寸敏感的产品。

三、工艺与可靠性优势

该电阻采用厚膜丝网印刷+高温烧结工艺,使用厚声优化的钌基电阻浆料,具备以下优势:

  • 参数一致性:浆料配方稳定,烧结过程可控,批量产品的阻值、TCR等参数偏差符合IEC 60115行业标准;
  • 长期稳定性:厚膜结构耐老化,长期使用阻值漂移小;通过-55℃~155℃热循环测试,耐湿、耐温冲击性能优异;
  • 成本性价比:相比薄膜精密电阻,厚膜工艺成本更低,在±1%精度需求场景下,是高性价比选型。

四、典型应用场景

基于参数特性,该电阻适配以下场景:

  1. 消费电子:智能手机/平板的PMU分压电阻、音频模块偏置电阻;智能音箱信号调理电路;
  2. 工业控制:小型传感器(温度/压力/流量)的信号放大/滤波电路;PLC的I/O接口限流电阻;
  3. 可穿戴设备:智能手环/手表的电池电压检测电路、心率传感器前置放大电路;
  4. 通信模块:蓝牙/WiFi模块的低功率射频匹配电路、SIM卡接口电路。

五、选型与使用注意事项

  • 选型替代:同参数(0402封装、1.4kΩ±1%、62.5mW)可兼容国巨、三星等品牌同规格产品;若需更高功率(100mW),可选厚声同系列0402封装100mW电阻;
  • 焊接要求:采用回流焊工艺,焊接峰值温度≤245℃(时间≤10秒),避免高温损坏电阻;
  • 降额提示:高温(>100℃)或高湿度环境下,需将功率降额至额定值的60%以下,延长产品寿命。

0402WGF1401TCE凭借小体积、宽温区、高一致性及成本优势,成为中小功率精密电路设计的常用选型之一。

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
