ERJ2RKF2492X是松下(PANASONIC)推出的0402封装厚膜贴片电阻,针对小型化、高可靠性电子设备设计,核心参数覆盖24.9kΩ±1%阻值、100mW额定功率及宽温区适应性,适用于消费电子、工业控制、汽车辅助电路等多场景。
该型号属于松下厚膜电阻系列的通用精密型产品,采用厚膜丝网印刷烧结工艺:在氧化铝陶瓷基底上印刷钌基电阻浆料,经高温烧结形成致密电阻层,再覆盖玻璃保护层——兼具成本优势与性能稳定性。相比薄膜电阻,厚膜工艺更适合批量生产,抗机械应力(冲击、振动)能力更强;相比线绕电阻,0402封装实现体积极小化,适配高密度PCB设计。
采用0402英制封装(公制1005),尺寸为1.0mm(长)×0.5mm(宽)×0.3mm(厚),是小型化设备的核心适配封装,可显著降低PCB布局面积,提升设计密度。
该型号因小封装、宽温区及稳定性能,广泛应用于以下领域:
松下对该型号进行多项可靠性测试,符合IEC 60068等国际标准:
ERJ2RKF2492X凭借小封装、宽温区及稳定厚膜工艺,成为小型化电子设备中通用精密电阻的优选型号,平衡了性能、成本与可靠性需求。

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.
