WR04X1023FTL 厚膜片式电阻器产品概述

一、产品定位与核心属性

WR04X1023FTL是华新科(Walsin)针对小型化、低功耗、高精度电子电路推出的厚膜片式固定电阻器。该产品聚焦三大核心优势:102kΩ精准阻值(1%精度)、1/16W(62.5mW)低额定功率、0402微型封装,同时具备宽温工作能力,可覆盖消费电子、工业控制、汽车电子等多场景需求。

二、电气性能参数详解

2.1 阻值与精度

  • 标称阻值:102kΩ(数字编码标识“1023”,即102×10³Ω);
  • 精度等级:±1%(工业级通用高精度标准,满足信号调理、分压电路的误差控制要求);
  • 温度系数(TCR):±100ppm/℃(温度每变化1℃,阻值波动0.01%;以工作温区-55℃~+155℃计算,最大阻值变化量约1.3kΩ,结合1%精度,总波动可控在±2.3%以内)。

2.2 功率与电压特性

  • 额定功率:62.5mW(1/16W)(低功耗设计,适配电池供电、低功耗MCU等场景);
  • 最大工作电压:50V(需注意:理论最大电压(V=\sqrt{P×R}≈80V),但实际限制为50V,需严格遵循以避免击穿)。

三、封装与物理特性

3.1 封装规格

采用0402封装(英制尺寸,对应公制1005),是当前微型电子设备的主流封装之一,典型尺寸:

  • 长度:1.0±0.1mm;
  • 宽度:0.5±0.1mm;
  • 厚度:0.4±0.1mm;
  • 端接宽度:0.3±0.1mm。

3.2 工艺与端接

  • 工艺:厚膜电阻工艺(在氧化铝陶瓷基板上印刷电阻浆料,经高温烧结、激光调阻而成,兼具成本优势与稳定性);
  • 端接:无铅锡膏端接(符合RoHS 2.0及REACH指令,适配回流焊、波峰焊标准工艺)。

四、环境适应性与可靠性

4.1 温区范围

  • 存储温度:-55℃~+125℃;
  • 工作温度:-55℃+155℃(覆盖工业级(-40+85℃)、汽车车身电子(-55~+150℃)等极端环境)。

4.2 可靠性验证

  • 负载寿命:1000小时、70℃/额定功率下,阻值变化≤±0.5%;
  • 湿度稳定性:85℃/85%RH、1000小时下,阻值变化≤±1%;
  • 焊接耐热性:符合J-STD-020标准,回流焊峰值260℃下无损坏。

五、典型应用场景

WR04X1023FTL因小型化、低功耗特性,广泛应用于:

  1. 消费电子:智能手机/平板的信号滤波、电源分压;智能穿戴的传感器接口;
  2. 工业控制:PLC输入输出模块的信号调理;小型传感器(温度/压力)前置放大;
  3. 汽车电子:仪表盘背光控制、低功耗辅助电路;
  4. 通信设备:基站射频偏置电路;光纤收发器信号匹配;
  5. 医疗电子:小型监护仪参数检测;便携式医疗设备电源管理。

六、选型与应用注意事项

  1. 功率降额:环境温度>70℃时,需按降额曲线使用(如100℃时降额至50%额定功率);
  2. 电压限制:实际电压不得超过50V,避免超压损坏;
  3. 焊接工艺:优先采用回流焊(避免波峰焊冲击),回流曲线匹配无铅端接(峰值245~260℃,时间≤30s);
  4. 存储条件:未开封产品存于25±5℃、40~60%RH环境,开封后72小时内使用完毕;
  5. 兼容性:无铅端接适配环保要求,建议使用无铅焊料焊接。

该产品以高性价比、稳定可靠的特性,成为微型电子电路中分压、滤波、偏置等环节的优选元件。

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
