CRCW120610K0FKEAC是VISHAY(威世) 旗下经典厚膜贴片电阻系列的核心型号,针对工业级及通用精密电路场景设计,具备稳定电气性能、紧凑封装尺寸与宽温区适应性,是电子系统中小信号处理、分压滤波、负载匹配等环节的可靠选择。
该型号属于VISHAY CRCW系列厚膜贴片电阻,采用1206标准表面贴装封装,核心参数聚焦10kΩ阻值、±1%精度、250mW功率,定位为「通用精密型厚膜电阻」——既满足消费电子、通信设备等领域的常规精密需求,又通过宽温区、抗恶劣环境设计适配工业控制、汽车辅助电子等场景,平衡了性能与成本。
型号标识解析:
10kΩ为E96系列标准阻值(覆盖1%精度的主流阻值范围),±1%精度可满足大部分信号处理电路的分压、偏置需求——例如运算放大器的增益设定、传感器信号的比例放大,避免因阻值偏差导致电路性能偏移。
250mW(0.25W)是1206封装的典型功率上限,适配小信号电路(如微控制器I/O口负载、传感器信号调理)。在25℃环境下可满功率稳定工作,若电路功耗接近极限,可适当降额(如125℃时降额至125mW)以提升寿命。
±100ppm/℃指每变化1℃,阻值漂移±100×10⁻⁶。以工作温区-55℃~155℃计算,总阻值漂移为210℃×100ppm=2.1%,叠加±1%精度后,实际阻值偏差范围约±3.1%,远优于普通碳膜电阻,适合温度变化剧烈的场景(如户外工业设备)。
-55℃+155℃符合工业级温度标准(商业级一般为0℃70℃),可在极端环境下稳定工作(如低温存储设备、高温工业炉周边电路)。
公制尺寸3.2mm(长)×1.6mm(宽)×0.55mm(厚,典型值),重量约0.01g——体积紧凑,可大幅节省PCB布局空间,适配高密度电路设计(如智能手机主板、小型医疗设备)。
采用厚膜丝网印刷技术:将电阻浆料印刷在96%氧化铝陶瓷基片上,经1000℃以上高温烧结固化,表面覆盖玻璃釉保护层——具备抗机械冲击、抗化学腐蚀能力,电阻层均匀性好,参数一致性高。
无铅(Pb-free)设计,符合RoHS、REACH等环保指令;焊盘采用锡银铜合金(无铅),适配标准SMT回流焊、波峰焊工艺,无需特殊焊接设备。
该型号因性能均衡,覆盖多领域应用:
VISHAY通过1000小时高温负载测试,确保阻值漂移≤0.5%(典型值),可满足产品5年以上使用寿命需求。
VISHAY作为全球电子元器件龙头厂商,其厚膜电阻技术积累超过50年,CRCW系列具备:
该型号以高性价比、稳定性能成为电子设计中「通用精密厚膜电阻」的首选,可满足从消费电子到工业级的多场景需求。

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.
