ERJPA2F2201X是松下(PANASONIC)推出的耐电涌型厚膜贴片电阻,针对电子电路中瞬态过压/过流(电涌)风险场景设计,兼顾小体积、高精度与宽温适应性,广泛适配消费电子、汽车电子及工业控制等领域的高密度电路需求。
该电阻属于松下耐电涌厚膜电阻系列(ERJPA系列),采用厚膜工艺制备,核心定位为电涌敏感电路的防护型电阻——相比普通厚膜贴片电阻,其电涌耐受能力显著提升,可有效抑制静电放电(ESD)、雷击感应、电源瞬态波动等对电路的冲击,降低电子设备故障概率。
采用0402封装(英制尺寸:0.04英寸×0.02英寸,公制尺寸:长1.00±0.15mm×宽0.50±0.15mm×厚0.35±0.05mm),是当前贴片电阻中体积最小的封装之一,适合高密度PCB布局(如智能手机主板、小型化通信模块)。
封装工艺采用无铅焊接兼容设计,引脚焊盘与PCB的焊接可靠性符合J-STD-002标准,支持回流焊、波峰焊等常规贴片工艺。
该产品以小体积、耐电涌、宽温稳定为核心优势,成为高密度电路中电涌防护与信号调理的优选元件,适配多领域的电子设备设计需求。

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.
