ERJ2RKF4302X是松下(PANASONIC)针对低功耗、高密度电路设计推出的0402封装厚膜贴片电阻,核心参数匹配工业级与消费电子的常规需求,以下从多维度展开详细概述。
ERJ2RKF4302X属于松下ERJ系列厚膜贴片电阻,型号编码明确对应产品特性:
核心参数清晰可查:
参数项 规格值 电阻类型 厚膜电阻 额定阻值 43kΩ 精度等级 ±1% 额定功率(25℃) 100mW 温度系数(TCR) ±100ppm/℃ 工作温度范围 -55℃~+155℃ 封装尺寸 0402(英制:1.0mm×0.5mm)厚膜电阻采用丝网印刷+高温烧结工艺制造,相比薄膜电阻(如镍铬合金薄膜)具有成本与性能的平衡优势:
ERJ2RKF4302X针对小功率场景优化了电阻膜层厚度,既保证100mW功率承载,又控制了封装尺寸。
0402封装(公制1005)是当前贴片电阻的主流小封装之一,尺寸仅为1.0mm(长)×0.5mm(宽)×0.3mm(厚),核心优势:
注:高温环境需按松下降额曲线使用,155℃时额定功率降至约25mW,需根据实际温度核算功率余量。
ERJ2RKF4302X的**±1%精度**属于工业级常用精度,可满足:
±100ppm/℃的温度系数,意味着温度每变化1℃,阻值变化≤0.01%。典型场景验证:
工作温度**-55℃~+155℃**覆盖多类场景:
松下厚膜工艺优化了电阻膜层与陶瓷基底的结合,耐受温度循环与湿度变化,降低故障率。
ERJ2RKF4302X的参数特性适配以下场景:
松下作为头部元器件厂商,产品符合严格标准:
综上,ERJ2RKF4302X是一款性价比高、适配性强的厚膜贴片电阻,适合对尺寸、精度、宽温有要求的低功耗电路设计。
Request for quote
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.
