ERJ2GEJ1R0X是松下(PANASONIC)推出的0402封装贴片厚膜电阻器,属于小功率通用型电阻范畴。该产品以紧凑尺寸、稳定性能为核心特点,适配高密度电路设计需求,广泛应用于消费电子、工业控制等多领域,是实现电流采样、分压滤波、信号匹配等基础功能的可靠元件。
标称阻值1Ω,精度±5%(E24系列常用精度等级),满足大多数常规电路对电阻值的偏差要求,无需额外高精度校准即可适配基础功能场景。
额定功率100mW(0.1W),结合1Ω阻值可计算出最大持续工作电流约0.316A(公式:(I=\sqrt{P/R})),适合小电流回路的电阻限流、采样应用。
范围为-100ppm/℃+600ppm/℃,属于厚膜电阻的典型温度特性——虽不及薄膜电阻的高精度温漂,但在常规温度变化(如-20℃+85℃)下,阻值漂移量可控制在合理范围(例如25℃到85℃,60℃变化下最大漂移为(600ppm/℃×60℃=3.6%),仍在±5%精度内)。
-55℃~+155℃,覆盖了工业级、部分汽车级(辅助电路)及户外设备的温度需求,可在极端环境下稳定工作。
0402英制封装(对应公制约1.0mm×0.5mm),是贴片电阻中尺寸较小的规格之一,能有效降低电路板的占用面积,提升电路密度,适配小型化电子设备(如智能手机、可穿戴设备)。
采用厚膜印刷工艺制造,在陶瓷基底上印刷电阻浆料并烧结而成。该工艺具有以下优势:
ERJ2GEJ1R0X的参数特性使其适配多种基础电路场景:
作为松下旗下的贴片电阻产品,ERJ2GEJ1R0X继承了品牌在被动元件领域的技术积累:
该产品凭借紧凑尺寸、稳定性能与宽环境适应性,成为高密度电路设计中基础电阻应用的优选方案。

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.
