VISHAY(威世)作为全球电子元器件领域的龙头企业,以高可靠性、精密制造和宽应用覆盖著称,其CRCW系列厚膜贴片电阻是工业级通用电阻的经典代表。CRCW040247K5FKED是该系列中一款小封装、低功耗的核心型号,型号命名遵循行业标准:
该产品采用表面贴装技术(SMT),适配自动化生产流程,是高密度PCB设计的理想选择。
CRCW040247K5FKED的参数经过平衡优化,满足多数通用场景的稳定需求:
标称阻值47.5kΩ,精度±1%——这是工业级电路的常用精度等级,无需额外校准即可用于信号调理、分压、限流等场景,保证电路性能一致性。
62.5mW(约0.063W)——符合0402封装的典型功率等级,适用于低功耗信号电路(如传感器接口、小信号放大),避免大电流导致的过热问题。
最大连续工作电压50V——需严格控制电路电压不超过此值,防止电阻击穿或性能退化;脉冲电压需参考VISHAY官方脉冲功率曲线(若应用场景涉及脉冲信号)。
±100ppm/℃——表示温度每变化1℃,阻值变化±47.5μΩ(47.5kΩ×100ppm)。在-55℃~+155℃的宽温范围内,阻值变化量可控,适合环境温度波动较大的应用(如工业现场、车载环境)。
-55℃至+155℃——覆盖工业级和部分汽车电子的温度要求,可在极端环境下稳定工作(如户外设备、高温车间)。
该产品采用0402厚膜贴片封装,具有以下特点:
CRCW040247K5FKED的参数特性使其适用于以下场景:
作为通用型厚膜贴片电阻,CRCW040247K5FKED是替代同类进口/国产电阻的高性价比选择,广泛应用于消费电子、工业控制、通信等领域。
综上,CRCW040247K5FKED凭借VISHAY的品质保障、平衡的参数特性和小封装优势,成为工业级通用电阻的优选型号,适用于多数低功耗、高密度的电子设计场景。
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.
