WR08X0000FTL是华新科(Walsin)推出的厚膜零欧姆表面贴装电阻器,本质是替代传统跳线的低阻连接元件。它采用0805英制封装(对应公制2012尺寸),专为自动化贴片生产设计,解决了传统跳线手工焊接效率低、可靠性差的问题,同时保留了低阻连接的核心功能,是PCB设计中常用的“隐形跳线”。
标称0Ω,精度±1%——并非绝对零电阻(实际寄生电阻极小),±1%的精度确保不同批次或温度下,阻值波动可忽略,不会影响电路连接的低阻特性。
125mW额定功率,对应最大承载电流1.5A——这是实际使用中更具参考性的参数(P=I²R,寄生电阻下,1.5A电流不会导致功率过载),适合小到中电流的连接场景。
150V直流/交流耐压——避免过压击穿,可满足大多数低压电路的安全需求(如消费电子、工业控制的常规电压范围)。
温度系数-200+400ppm/℃,工作温度-55℃+155℃——工业级宽温范围,适应从低温户外设备到高温电源模块内部的稳定工作,温度变化对阻值的影响在可接受范围内。
0805(2.0mm×1.2mm)——标准表面贴装尺寸,兼容主流PCB设计软件的封装库,焊接工艺适配回流焊、波峰焊,良率高。
0805封装是电子行业通用标准,具有以下适配优势:
华新科作为全球知名被动元器件制造商,在厚膜电阻领域工艺成熟:
WR08X0000FTL覆盖多领域:
WR08X0000FTL是高性价比的厚膜零欧贴装电阻,凭借华新科的可靠品质、工业级宽温特性、标准封装适配性,成为替代传统跳线的首选元件,广泛应用于消费电子、工业控制、车载电子等领域,有效提升电路设计灵活性与生产效率。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
