BOURNS CR0402-J/-000GLF是一款针对高密度PCB设计优化的厚膜贴片0Ω电阻,核心定位为替代传统插件跳线、实现电路低阻抗连接的基础元件。其小体积、宽温稳定的特性,广泛适配消费电子、工业控制、通信设备等领域的常规与恶劣环境应用,解决了传统跳线占用空间大、可靠性低的痛点。
在额定功率与25℃环境下,连续工作10000小时后,阻值变化率≤1%,满足工业设备5年以上使用寿命要求。
传统插件跳线需手工焊接,易出现虚焊、占用空间大;本产品可直接贴装于PCB,实现不同线路层/焊点的连接,提升生产效率与可靠性,常见于手机主板、平板电池保护板。
在4G/5G基站、路由器等射频设备中,用于接地或信号路径的低阻抗连接,减少射频信号损耗(寄生电阻<50mΩ可降低信号衰减),提升通信稳定性。
PLC、变频器等工业控制器中,作为滤波电路的旁路元件,抑制电磁干扰(EMI),避免信号失真影响设备运行。
适配汽车座舱、车身控制模块的低阻抗连接(如传感器信号路径),宽温特性满足汽车-40℃~+85℃的工作环境(需确认具体车规认证,本产品基础参数覆盖该温区)。
实际使用功率需低于额定功率的70%(即≤43.75mW),避免过热导致阻值漂移或封装损坏;若需更高功率,需选用0603或更大封装的0Ω电阻。
若需精密低阻抗(如电流检测电路),需确认实际寄生电阻是否满足需求(本产品±5%精度适合常规连接,精密场景建议选用激光微调0Ω电阻)。
本产品凭借小体积、宽温稳定、低阻抗的特性,成为高密度PCB设计中替代传统跳线的优选元件,覆盖从消费电子到工业控制的多场景需求,是BOURNS厚膜电阻系列中的经典基础款。

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.
