ERJPA2J101X是松下(PANASONIC)推出的一款通用型厚膜贴片电阻,针对电子电路中基础阻值需求设计,以小体积、宽温稳定为核心优势,适配多种消费电子、工业控制及小型家电场景。以下从核心参数、性能特点、应用场景等维度展开概述。
ERJPA2J101X的核心参数聚焦通用电路的基础需求,关键指标清晰适配常见设计场景:
该产品定位为“高性价比通用小体积电阻”,无需高精度或高功率需求的设计中,可替代同参数竞品,降低BOM成本。
100Ω是电子电路的“基础阻值标杆”,常见于分压网络、LED限流(小电流LED)、运算放大器偏置等场景。±5%的精度无需额外校准,可满足消费电子、小型家电等对精度要求不苛刻的设计,同时避免了高精度电阻的成本溢价。
额定功率200mW意味着最大允许功耗为0.2W,实际使用需同时满足功率+电压双限制:
±200ppm/℃的温度系数表示:温度每变化1℃,阻值变化0.02%。以-55℃至+155℃全温区为例,阻值最大变化量仅4.2Ω(100Ω×210℃×200ppm),仍在±5%精度范围内,确保工业现场、高温环境下电路性能稳定。
ERJPA2J101X采用0402封装,尺寸约1.0mm×0.5mm×0.35mm,具备两大核心优势:
结合参数与性能,ERJPA2J101X的适配场景覆盖多领域:
作为松下旗下产品,ERJPA2J101X具备可靠的品质背书:
综上,ERJPA2J101X是一款性价比突出的通用厚膜贴片电阻,以小体积、宽温稳定、成本可控为核心优势,适配多种电子设计场景,是工程师基础电阻选型的可靠选择。

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.
