华新科WR04X1823FTL厚膜固定电阻器产品概述

华新科(Walsin)推出的WR04X1823FTL是一款专为小型化、低功耗电子设备设计的厚膜固定贴片电阻器,凭借平衡的电性能参数、紧凑的封装尺寸及宽温适应性,成为消费电子、IoT终端、工业控制等领域的主流选型之一。

一、产品基本属性

该电阻器的核心基础信息明确,具体如下:

  • 品牌型号:华新科(Walsin)WR04X1823FTL
  • 电阻类型:厚膜贴片电阻(采用厚膜印刷工艺,兼顾成本与可靠性)
  • 封装规格:标准0402贴片封装(尺寸约0.4mm×0.2mm,体积紧凑)
  • 阻值编码:1823(对应阻值182×10³Ω=182kΩ)

二、核心电性能参数

WR04X1823FTL的电性能参数经过优化,适配多数常规电路需求:

  1. 阻值与精度:额定阻值182kΩ,精度±1%——满足一般信号调理、分压、限流电路对阻值偏差的要求,无需过度追求高精度带来的成本增加;
  2. 功率与电压:额定功率1/16W(62.5mW),最大工作电压50V——适合低功耗电路(如IoT传感器、便携设备),避免功率冗余;
  3. 温度特性:温度系数±100ppm/℃,工作温度范围-55℃~+155℃——温度每变化1℃,阻值相对变化约0.01%,在工业级宽温环境(如户外传感器、车载周边模块)下仍能稳定工作;
  4. 可靠性参数:厚膜工艺赋予其较好的耐湿性与抗冲击性,符合常规贴片电阻的可靠性标准。

三、封装与物理特性

0402封装是当前贴片电阻中尺寸较小的规格之一,具有以下特点:

  • 体积紧凑:可显著降低PCB板的占用面积,适合高密度布线设计(如智能手机主板、智能手表模块);
  • 焊接兼容性:适配回流焊、波峰焊等常规贴片焊接工艺,焊接流程与多数贴片元件一致,无需特殊工艺调整;
  • 重量轻:单颗重量约几毫克,对便携设备的整体重量影响极小。

四、典型应用场景

结合WR04X1823FTL的参数特性,其主要应用场景包括:

  1. 消费电子:智能手机、智能手环、机顶盒等便携/小型设备的信号调理电路(如音频滤波、电源分压);
  2. IoT终端:环境传感器节点(温度、湿度传感器)的信号放大与限流电路,适配低功耗与宽温需求;
  3. 工业控制:小型PLC模块、电机驱动辅助电路的分压与反馈回路,利用宽温特性适应工业现场环境;
  4. 小型电源:5V/3.3V低压电源的输出分压检测电路,功率与电压参数匹配低压电源需求。

五、产品优势与适配性

相较于同封装的其他电阻器,WR04X1823FTL具有以下优势:

  • 成本与性能平衡:厚膜工艺降低了生产成本,同时±1%精度、±100ppm/℃温度系数满足多数常规电路需求,无需为极端参数支付额外费用;
  • 宽温适应性:-55℃+155℃的工作范围覆盖了工业级与汽车级(部分低要求场景)的温度需求,比常规商业级电阻(0℃70℃)更具环境适应性;
  • 批量适配性:华新科的厚膜电阻产能稳定,适合大规模量产项目,供货周期可控。

六、选型与使用注意事项

  1. 功率降额:实际应用中需结合环境温度进行功率降额设计(如155℃环境下,建议功率不超过额定值的50%),避免过热导致阻值漂移;
  2. 焊接温度:回流焊峰值温度建议不超过260℃,焊接时间控制在10秒以内,防止损坏厚膜层;
  3. 对比选型:若需更高精度(如±0.1%),可选择华新科薄膜电阻系列;若需更大功率(如1/8W),可选择0603封装的同阻值型号。

整体来看,华新科WR04X1823FTL是一款性价比突出的常规厚膜贴片电阻,适合对尺寸、功耗、宽温有要求的主流电子设备设计,是工程师选型库中的常见选项。

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
