WR06X1542FTL 厚膜固定电阻产品概述

一、产品基本信息

WR06X1542FTL是华新科(Walsin) 推出的厚膜固定电阻,属于其WR06系列(常规对应0603封装,公制尺寸1.6mm×0.8mm×0.45mm)。该产品针对小功率、高精度、宽温应用场景优化,型号命名逻辑清晰:

  • WR06:华新科0603封装系列标识;
  • X:子系列工艺优化标识(侧重宽温稳定性);
  • 1542:阻值代码(154×10²=15.4kΩ);
  • FTL:精度(±1%)、温度系数(±100ppm/℃)及封装的组合定义。

二、核心技术参数

该产品关键性能符合工业级标准,具体如下:

  1. 阻值与精度:标称15.4kΩ,精度±1%(实际阻值范围15.246kΩ~15.554kΩ),满足信号调理、分压电路的精度需求;
  2. 功率规格:额定功率100mW(1/10W),最大允许功率100mW(无降额时),适配小功率电路设计;
  3. 工作电压:最大75V,计算最大电流约4.87mA(I=V/R=75V/15.4kΩ);
  4. 温度系数:±100ppm/℃(温度每变1℃,阻值漂移±0.01%),100℃温差下漂移仅±15.4Ω,宽温稳定性优异;
  5. 工作温度:-55℃~+155℃,覆盖极端低温(户外工业)和高温(设备内部)场景;
  6. 封装:0603(1.6×0.8mm),体积小巧,适合高密度PCB设计。

三、设计特点与优势

基于厚膜丝网印刷+烧结工艺,该产品具备以下核心优势:

  1. 稳定性与可靠性:厚膜电阻层抗过载能力强,长期使用阻值漂移≤0.1%(1000小时老化后),符合华新科工业级品质;
  2. 宽温适应性:±100ppm/℃温度系数结合-55~+155℃范围,可满足汽车电子、工业控制等宽温场景;
  3. 小体积大功率密度:1/10W功率在0603封装中实现高功率密度,适配智能手机、可穿戴设备等小型化终端;
  4. 成本平衡:相比薄膜电阻,厚膜工艺在保证±1%精度的前提下,成本降低约30%,适合大规模量产。

四、典型应用场景

该产品覆盖多领域小功率电路需求:

  1. 工业控制:PLC模拟量输入调理、传感器信号分压、电机驱动辅助电路(宽温适配工厂环境);
  2. 消费电子:手机/平板电源分压、音频滤波、LED背光电流调节(小体积适配紧凑设计);
  3. 汽车电子:仪表盘背光控制、胎压监测信号调理(部分场景可覆盖155℃以内工作温度);
  4. 通信设备:路由器射频匹配、基站电源电压采样(低功耗匹配通信设备需求);
  5. 医疗仪器:监护仪生理信号调理、便携式医疗设备电源电路(稳定阻值保证测量精度)。

五、使用注意事项

为确保性能与寿命,需注意:

  1. 功率降额:实际工作功率建议≤50mW(额定的50%),延长使用寿命;
  2. 电压限制:避免超过75V直流/交流电压,防止击穿;
  3. 焊接工艺:回流焊温度≤260℃(峰值时间≤10秒),避免过热损坏电阻层;
  4. 存储条件:未焊接产品存储在-20℃~+40℃、湿度≤60%环境,防止引脚氧化。

六、总结

WR06X1542FTL是一款高性价比厚膜电阻,兼具高精度、宽温稳定、小体积特点,覆盖工业、消费电子、汽车等多领域。其核心参数可满足多数小功率电路设计需求,是工程师小型化、宽温设备设计的可靠选择。

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
