ERJ2RKF5113X是松下(PANASONIC)推出的一款小功率高精度厚膜贴片电阻,针对高密度小型化电路设计,核心参数适配多类电子设备的基础无源需求。以下从核心身份、参数特性、工艺封装、应用场景等维度展开具体概述。
ERJ2RKF5113X属于松下ERJ系列厚膜贴片电阻,封装为0402(英制尺寸0.04in×0.02in,公制1005),是一款面向消费电子、小型工业控制等领域的基础电阻器件。其核心定位是小体积+高精度+宽温适应性,兼顾成本与性能,适合对空间敏感且需稳定阻值的电路场景(如分压网络、信号反馈回路)。
标称阻值511kΩ(即511×10³Ω),精度等级±1%——这一精度高于常规±5%通用电阻,可避免因阻值偏差导致的信号失真或控制精度下降,适配运算放大器反馈、电压分压等对误差敏感的电路。
±100ppm/℃——表示温度每变化1℃,阻值变化±0.01%。例如,温度从25℃升至125℃(变化100℃),阻值变化约±1%,与精度等级匹配,保证宽温范围内性能稳定。
-55℃+155℃——覆盖工业级(-40℃85℃)、汽车级(-40℃125℃)甚至部分高温场景(如靠近热源的电路),环境适应性优于常规商业级(0℃70℃)电阻。
体积仅1.0mm×0.5mm,是小型化贴片电阻的主流封装之一,可显著降低PCB布局空间,适配智能手机、可穿戴设备等对尺寸要求苛刻的产品。其焊接兼容性强,支持无铅回流焊工艺,符合环保要求。
采用丝网印刷钌系电阻浆料在氧化铝陶瓷基底上烧结而成:
结合参数与工艺特性,ERJ2RKF5113X适用于以下场景:
松下作为全球电子元器件龙头,ERJ系列电阻通过RoHS(无铅)、REACH等环保认证,部分型号符合IATF16949汽车电子标准;生产工艺严格遵循ISO9001质量管理体系,产品一致性好,被苹果、华为、三星等知名品牌广泛采用,品质得到市场验证。
ERJ2RKF5113X凭借小体积、高精度、宽温适应性等特点,成为高密度电路设计中不可替代的基础无源器件,适配多领域电子设备的性能需求。

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.
