ERJ2RKF1300X是松下(PANASONIC)推出的0402封装厚膜贴片电阻,专为高密度贴装、宽温环境下的稳定应用设计,兼顾阻值精度、功率承载能力与长期可靠性,广泛适配消费电子、工业控制、汽车电子等领域的小功率电路需求。
标称阻值为130Ω,精度等级**±1%**,可直接用于无需更高精度(如0.1%)的分压网络、电流采样、信号匹配等场景,减少后期校准成本。
额定功率100mW(0.1W),适用于小电流(如≤27.8mA,由P=I²R计算)电路的限流、分压,避免大电流过载导致的电阻失效。
温度系数为**±100ppm/℃**,表示温度每变化1℃,阻值变化约±0.013Ω(130Ω×100ppm),在宽温范围内阻值漂移控制在低水平,适合温度变化剧烈的环境。
覆盖**-55℃至+155℃**,超出工业级(-4085℃)与汽车级(-40125℃)常规要求,可应对户外、车载、高温工业设备等严苛场景。
厚膜膜层具备较好的抗浪涌能力(瞬间过压下阻值变化≤0.5%),长期负载稳定性符合松下内部标准:1000小时额定功率负载试验后,阻值变化≤0.5%。
采用0402英制封装,对应公制尺寸约:
焊盘设计符合IPC-A-610标准,适配回流焊、波峰焊工艺(波峰焊需注意引脚浸润性);小型化设计可有效节省PCB空间,适合便携式设备(如智能手表、无线耳机)及高密度电路板(如服务器主板、通信模块)的贴装需求。
ERJ2RKF1300X凭借小型化封装、高阻值精度、宽温稳定性及松下的可靠性工艺,成为多领域小功率电路的优选厚膜贴片电阻,可平衡性能与成本,满足不同场景下的实用需求。

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.
