松下ERJ2RKF5361X是一款针对小型化高精度电路设计的厚膜贴片电阻,凭借紧凑的0402封装、稳定的电气性能及宽温适应性,成为消费电子、工业控制、汽车电子等领域的高性价比解决方案。以下从核心参数、封装特性、应用场景等维度展开详细概述。
该电阻聚焦小功率通用高精度需求,以厚膜工艺为基础,兼顾体积小型化与性能稳定性,主要解决传统插件电阻无法满足的高密度组装场景问题,同时满足一般工业及消费类设备对阻值精度、温度稳定性的基本要求,无需额外校准即可实现稳定的电路功能。
ERJ2RKF5361X的标称阻值为5.36kΩ,精度等级为**±1%**,属于工业级通用高精度范畴。该精度可满足大多数电路的设计需求,例如分压电路的比例控制、运算放大器的反馈网络、电源限流保护等场景,避免因阻值误差导致的电路性能偏差。
温度系数(TCR)为**±100ppm/℃,即温度每变化1℃,阻值变化±0.01%。结合-55℃~+155℃**的工作温度范围,当环境温度从25℃(基准温度)变化到155℃时,阻值最大变化量为±1.3%,叠加初始±1%精度,总误差控制在±2.3%以内,可稳定应对高低温环境下的电路性能要求。
采用0402封装(英制尺寸:0.04″×0.02″,公制约1.0mm×0.5mm),是目前小型化电子设备中常用的贴片封装之一。厚膜工艺的封装结构具有以下优势:

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
