WR06X1003FTL 厚膜贴片电阻产品概述

一、产品基本信息

WR06X1003FTL由华新科(Walsin)推出,属于厚膜贴片电阻系列,型号标识清晰对应核心参数:

  • 品牌与系列:华新科电阻产品,前缀“WR”为品牌电阻代码;
  • 封装:0603(英制命名,对应公制1608),尺寸为1.6mm×0.8mm×0.45mm(长×宽×厚,典型值),适配高密度PCB布局;
  • 阻值与精度:型号“1003”为阻值代码(前三位有效数字100,第四位倍率10³),标称阻值100kΩ,精度±1%;
  • 后缀含义:“FTL”包含精度(F对应±1%)、功率等级(L关联100mW额定功率)等参数定义。

二、核心电气参数

该电阻关键参数经标准化测试,适配通用电路的小信号、中等精度需求:

  1. 阻值与精度:标称100kΩ,实际阻值范围99kΩ~101kΩ,满足多数信号调理、分压电路的精度要求;
  2. 功率与电压:额定功率100mW(0.1W),最大工作电压75V。需注意双参数限制:实际使用时需同时满足( P \leq 100mW )和( V \leq 75V )(如75V工作时功率为56.25mW,未超额定值);
  3. 温度特性:温度系数±100ppm/℃(即每升高1℃,阻值变化±0.01%)。以25℃为基准,125℃时阻值变化±1kΩ(仍在±1%精度内),适配宽温环境;
  4. 工作温度范围:-55℃~+155℃,覆盖工业、汽车电子等领域的高低温场景。

三、封装与工艺特性

采用厚膜丝网印刷工艺,核心结构为:

  • 基板:氧化铝陶瓷(Al₂O₃),耐高温、抗机械应力;
  • 电阻层:钌基厚膜浆料,经高温烧结形成稳定电阻值;
  • 电极:银钯合金(Ag-Pd),焊接可靠性高;
  • 保护层:环氧树脂,防潮、防腐蚀。

该工艺兼具成本优势(比薄膜电阻低30%~50%)与可靠性(抗湿热、抗老化性能优于部分薄膜电阻),适合批量应用。

四、典型应用场景

因小体积、宽温、中等精度的特点,广泛用于:

  1. 工业控制:PLC模拟量输入模块的分压电阻、PT100温度传感器的信号调理电阻;
  2. 消费电子:手机快充电路的电压反馈电阻、蓝牙耳机的信号匹配电阻;
  3. 汽车电子:车载压力传感器的信号调理、仪表盘背光电路的限流电阻(适配-40℃~+85℃车载环境);
  4. 通信设备:路由器、交换机的信号分压网络、电源模块的反馈电阻。

五、优势与使用注意事项

1. 核心优势

  • 可靠性:华新科厚膜电阻经高温老化、湿热循环测试,失效率≤0.1%/1000小时;
  • 宽温适配:-55℃~+155℃范围满足恶劣环境需求;
  • 高密度布局:0603封装可减少PCB板级空间占用30%以上;
  • 成本效益:厚膜工艺平衡性能与成本,适合中低端批量产品。

2. 注意事项

  • 降额使用:环境温度>70℃时,需按华新科降额曲线使用(如125℃时功率降额至50mW);
  • 焊接规范:回流焊峰值温度≤260℃(时间≤10秒),波峰焊温度≤250℃(时间≤5秒),避免过热损坏电阻层;
  • 电压限制:严禁超过75V最大工作电压,否则可能导致电阻击穿。

六、选型补充说明

若需调整参数,可参考:

  • 更高精度(±0.1%):切换至华新科薄膜电阻系列(如WR薄膜款);
  • 更大功率(1/4W):选用0805封装(如WR08X1003FTL);
  • 更低温度系数(±50ppm/℃):选择激光微调厚膜电阻或薄膜电阻。

WR06X1003FTL作为华新科经典厚膜电阻,以稳定的性能、合理的成本,成为通用电路的优选元件之一。

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
