ERJ3GEYJ820V是松下(PANASONIC)针对常规电路设计推出的0603封装贴片厚膜电阻器,凭借稳定的电气性能、紧凑的封装尺寸及宽温适应性,广泛应用于消费电子、工业控制、通信等领域的基础电路场景。
该产品采用厚膜电阻工艺制造,通过在高纯度氧化铝陶瓷基底上印刷钌基电阻浆料并高温烧结而成,兼具成本优势与可靠性,属于松下ERJ系列常规精度贴片电阻的典型型号。核心用于电压分压、电流限流、信号匹配、负载偏置等非精密电路功能,无需额外校准即可适配多数量产设计需求。
标称阻值为82Ω,精度等级±5%,满足常规电路对阻值匹配的基本要求。例如:
温度系数为**±200ppm/℃**,即温度每变化1℃,阻值变化量为±82Ω×0.00002%=±0.0164Ω。在-55℃至+155℃的宽温范围内,阻值漂移可控,适合温度波动较大的环境(如户外工业设备、车载低温启动场景)。
采用0603封装(英制尺寸:0.06英寸×0.03英寸,对应公制1.6mm×0.8mm),体积小巧,适配高密度PCB布局,尤其适合便携式设备的小型化设计(如智能手机、智能穿戴)。
覆盖**-55℃至+155℃**,满足工业级环境的温度要求(如低温启动、高温运行),无需额外增加温度补偿电路,降低设计成本。
产品经过松下严格的可靠性验证,包括:
松下作为全球电子元器件领域的领先厂商,ERJ系列电阻采用标准化生产流程,原材料与工艺管控严格,产品符合IEC、JIS等国际标准,广泛应用于国内外主流电子厂商的量产产品中,可提供稳定的供应链支持与技术服务。

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.
