WR08X000PTL 厚膜零欧姆电阻产品概述

一、产品核心定位与基础特性

WR08X000PTL是华新科(Walsin)推出的0805封装厚膜零欧姆贴片电阻,定位于常规电子电路中的短接、跳线及低阻匹配场景。作为厚膜电阻系列的一员,其核心设计围绕“小功率、高可靠性、易贴装”展开,适配多数消费电子、工业控制及通信设备的电路需求,无需额外导线即可实现节点短接,提升PCB布局灵活性。

二、关键电气性能参数详解

  1. 阻值与功能:标称阻值为0Ω(俗称“跳线电阻”),实际应用中可等效为“无损耗短接”,替代传统导线或手动跳线,简化电路设计(无需预留导线孔)。
  2. 功率与电压限制:额定功率125mW(毫瓦),最大工作电压150V(直流/交流)。实际使用需同时满足双限制:
    • 当电压为150V时,最大允许电流约0.83mA(由(I=P/V)推导:(125mW/150V≈0.83mA));
    • 若电流超过0.83mA,需以功率值反推最大电压((V=\sqrt{P×R}),因(R≈0),实际需结合电路实际功耗控制)。
  3. 温度稳定性:温度系数(TCR)范围为(-200ppm/℃)至(+400ppm/℃),反映阻值随温度的漂移特性。在(-55℃)至(+155℃)的宽温范围内,等效阻值变化可控,满足工业级环境下的电路稳定性需求。
  4. 工作温度范围:(-55℃)至(+155℃),覆盖户外设备、高温车间等场景的温度波动,适配多数工业控制、汽车电子的常规环境。

三、物理封装与可靠性设计

  1. 封装规格:采用0805封装(英制:0.08英寸×0.05英寸,公制2012封装),尺寸仅约(2.0mm×1.2mm),适合高密度PCB布局,支持自动化表面贴装(SMT)工艺,生产效率高。
  2. 厚膜工艺优势:通过丝网印刷、高温烧结制成,相比薄膜电阻成本更低,且具有良好的耐湿性、抗机械应力能力,长期使用无明显阻值漂移。
  3. 绝缘与防护:陶瓷基片+环氧树脂涂层封装,绝缘性能优异(可承受150V工作电压),同时具备抗污染、抗静电能力,适配复杂环境下的应用。

四、典型应用场景

  1. 电路跳线与短接:替代导线简化PCB设计,常见于智能手机、路由器等高密度电路的节点短接(如电源轨连接、信号路径跳接)。
  2. 小电流检测:在mA级小电流场景中,利用其等效低阻特性实现电流检测(需配合高精度运放),但需严格控制功率(避免过流烧毁)。
  3. 调试与匹配:作为射频电路(RF)的阻抗匹配元件(如天线与前端的短接匹配),或调试点(方便后期更换/短接),提升电路调试灵活性。
  4. 工业与汽车电子:宽温范围适配工业PLC模块、车载中控、传感器电路等场景,满足高温/低温环境下的长期稳定运行。

五、品牌与品质保障

WR08X000PTL由华新科(Walsin)生产,该品牌是全球知名被动元件制造商,产品符合RoHS 2.0、REACH环保标准,通过ISO 9001质量管理体系认证。其厚膜电阻系列在消费电子、通信、工业领域应用广泛,品质稳定可靠,可降低电路设计的故障率。

综上,WR08X000PTL以小巧封装、宽温性能、可靠设计,成为常规电子电路中零欧姆短接、跳线及匹配场景的实用选择,适配多数中低端至工业级电路需求。

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
