ERJ2RKF2200X是松下(PANASONIC)推出的精密级厚膜贴片电阻器,属于松下经典ERJ系列贴片电阻产品。该型号以小封装、高精密、宽温适应性为核心特点,适配高密度PCB设计与极端环境应用场景。
型号命名逻辑参考松下贴片电阻规范:
该产品针对精密电路设计优化,关键指标如下:
此外,厚膜电阻结构赋予其低噪声特性(噪声电压约为碳膜电阻的1/3),适合对信号噪声敏感的电路(如传感器信号调理)。
采用0402英制封装,对应公制尺寸为1.0mm(长)×0.5mm(宽)×0.35mm(厚),是当前小型化电子设备的主流封装之一,可显著减少PCB占用面积,支持高密度布局(如手机主板、微型医疗仪器)。
兼容回流焊、波峰焊等标准贴片焊接工艺,焊接后焊点强度符合IPC-A-610标准;产品采用“陶瓷基板+电阻浆料+镍金电极”结构,机械强度高,抗振动(10g~2000Hz)、抗冲击(1000m/s²)性能满足工业设备振动测试要求。
ERJ2RKF2200X的参数特性适配多领域应用:
ERJ2RKF2200X凭借其高精密、小封装、宽温适应性,成为消费电子、工业控制等领域的高性价比贴片电阻选择。

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.
