CRWC0402165KFKED是VISHAY(威世)推出的0402封装厚膜贴片电阻,属于CRCW系列通用型贴片电阻产品,主打小型化、高可靠性与精准阻值,适用于对空间紧凑性和电气性能稳定性要求较高的电子电路设计。
该电阻采用厚膜工艺制造,结合0402(英制)/1005(公制)小封装设计,兼具成本优势与性能稳定性,是VISHAY针对消费电子、工业控制、通信等领域开发的成熟产品。核心定位为通用型精准贴片电阻,可替代同参数其他品牌产品,满足大多数小型化电路的阻值与功率需求。
标称阻值为165kΩ,精度等级**±1%**,优于普通±5%精度电阻,适合信号分压、运算放大器反馈网络、滤波电路等需准确阻值匹配的场景,可减少电路参数误差累积。
温度系数**±100ppm/℃**,表示温度每变化1℃,阻值变化约0.01%。在工作温度范围(-55℃~+155℃)内,最大阻值变化量为2.1%,结合±1%精度,极端温度下总阻值偏差±3.1%,满足宽温环境稳定性要求。
采用0402封装(尺寸≈1.0mm×0.5mm),是贴片电阻最小规格之一,适合高密度PCB布局(如智能手机主板、可穿戴设备模块),有效节省电路空间。
宽温范围**-55℃+155℃**,覆盖工业级(-40℃+85℃)、汽车级(部分场景)及航空航天应用温度需求,可在极端环境下稳定工作。
厚膜工艺通过丝网印刷、烧结制造,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好,抗过载能力适中,适合长期稳定运行。
VISHAY作为全球被动元件龙头,CRCW系列电阻经严格可靠性测试(高温存储、温度循环、湿度、机械振动等),符合IEC、JEDEC标准,长期性能稳定。无铅无卤,符合RoHS环保要求,适配绿色电子产品设计。
总结:CRWC0402165KFKED是一款小封装、精准度、宽温适应性的厚膜贴片电阻,兼具成本优势与可靠性,广泛适用于消费电子、工业、通信等领域的小型化电路设计。

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.
