ERA3VEB1003V是松下针对高精度、高密度电子设计推出的薄膜贴片电阻,核心定位为「小功率高稳定型」。其优势集中在三个关键维度:
标称阻值为100kΩ(即10^5Ω),精度±0.1%意味着实际阻值范围在99900Ω~100100Ω之间,偏差控制在100Ω以内。这种精度可避免因电阻误差导致的信号失真(如A/D转换精度下降、放大器增益偏移)。
温度系数(TCR)为**±25ppm/℃,即每变化1℃,阻值变化约2.5Ω**(100kΩ×25×10^-6)。若环境温度从-55℃升至155℃(温差210℃),阻值总变化仅525Ω,远低于普通电阻的2100Ω以上变化量。
覆盖**-55℃~+155℃**,满足工业级、汽车级(部分场景)的极端温度需求,可在高温车间、低温户外设备中长期可靠工作。
采用0603贴片封装(英制编号,对应公制尺寸1.6mm×0.8mm,厚度≈0.5mm),具备以下实用特性:
ERA3VEB1003V的性能特点使其适配多个高精度领域:
松下对该产品的可靠性管控严格:
作为松下薄膜电阻系列的核心产品,ERA3VEB1003V延续了品牌的高品质基因:
该产品以「高精度+高稳定+小体积」的组合,成为精密电子设计中替代普通电阻的优选方案。

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.
