WR06X1803FTL 厚膜片式电阻产品概述

WR06X1803FTL是华新科(Walsin)推出的一款0603封装厚膜片式精密电阻,针对高密度电路设计优化,兼具小体积、高稳定性与宽环境适应性,广泛适用于消费电子、工业控制、汽车电子等领域的信号调理与功率控制场景。

一、产品基本属性

该电阻属于厚膜片式电阻范畴,采用表面贴装(SMD)封装,尺寸对应国际标准0603(公制标识常为603),体积小巧(约1.6mm×0.8mm),可有效节省PCB布局空间。作为华新科常规精密电阻系列产品,其核心设计围绕高一致性、宽温稳定展开,满足不同场景下的长期可靠运行需求。

二、核心性能参数解析

(一)阻值与精度

标称阻值为180kΩ,精度等级为**±1%**,属于精密电阻范畴。该精度可满足多数信号处理电路的要求(如分压网络、运算放大器反馈回路、传感器信号校准等),避免因阻值偏差导致的信号失真或控制误差。

(二)功率与电压限制

  • 额定功率:100mW(1/10W),为小功率片式电阻的典型规格;
  • 最大工作电压:75V。需注意功率与电压的关联:实际使用中需同时满足「功率≤100mW」与「电压≤75V」,取两者限制下的较小值(经计算:75V²/180kΩ≈31.25mW,因此电压限制更严格,实际应用需重点关注电压不超75V)。

(三)温度系数与工作温度

  • 温度系数(TCR):±100ppm/℃,即温度每变化1℃,阻值变化约±0.018Ω,可保证宽温环境下的阻值稳定性;
  • 工作温度范围:-55℃~+155℃,覆盖工业级宽温要求,适用于户外、车载等极端温度场景。

三、适用场景与应用优势

(一)典型应用场景

  1. 消费电子:智能手机/平板电脑的电源管理模块(如DC-DC转换反馈、电池保护电路)、音频电路(音量控制分压);
  2. 小型工业设备:传感器信号调理(如温度传感器、压力传感器的信号放大与校准)、PLC输入/输出接口的限流;
  3. 汽车电子:低功耗车载控制单元(如车身灯光控制、传感器信号采集);
  4. 通信设备:小型基站的射频辅助电路(如滤波器匹配网络)。

(二)核心应用优势

  1. 小体积高密度:0603封装适配高密度PCB设计,满足小型化产品的布局需求;
  2. 高稳定性:厚膜工艺结合华新科的生产管控,阻值一致性好,长期使用漂移小;
  3. 宽环境适应性:-55℃~+155℃工作温度与±100ppm/℃ TCR,可应对复杂工况;
  4. 环保合规:符合RoHS、REACH等国际环保标准,无铅焊接兼容。

四、可靠性与品质保证

华新科作为全球知名被动元件厂商,WR06X1803FTL通过多重可靠性测试验证:

  1. 耐老化性能:厚膜电阻的烧结工艺使其抗电迁移能力优于薄膜电阻,长期通电阻值漂移率≤0.5%(典型值);
  2. 环境测试:通过温度循环(-55℃~155℃,1000次)、湿热测试(85℃/85%RH,1000h)等工业级测试;
  3. 焊接兼容性:支持回流焊、波峰焊等表面贴装工艺,焊接后无开裂、阻值变化风险。

五、应用注意事项

  1. 功率降额:实际使用功率建议不超过额定功率的80%(即80mW),避免长期过载导致性能下降;
  2. 静电防护:精密电阻对静电敏感,生产/测试过程需佩戴防静电手环,使用离子风机消除静电;
  3. 焊接参数:遵循华新科推荐的回流焊温度曲线(峰值温度≤245℃,时间≤10s),避免高温损坏;
  4. 电压限制:严禁超过75V工作电压,否则可能导致电阻击穿或阻值突变。

综上,WR06X1803FTL是一款兼顾小体积、精密性与可靠性的厚膜片式电阻,可满足多数中低端精密电路的设计需求,是华新科针对消费电子与小型工业场景的高性价比选择。

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
