ERJ3EKF2211V是松下(PANASONIC)推出的0603封装厚膜贴片电阻,专为小体积、高精度、低功耗电子电路设计。其核心定位是满足消费电子、工业控制、小型医疗设备等领域对“紧凑空间+精准阻值+稳定性能”的双重需求,是替代传统插件电阻、提升电路集成度的理想选择。该产品基于成熟厚膜工艺制造,兼顾成本控制与性能可靠性,适用于批量标准化生产。
标称阻值为2.21kΩ,精度达**±1%**——即阻值范围稳定在2.1879kΩ~2.2321kΩ之间,可精准匹配分压电路、运算放大器反馈网络、传感器信号调理等需要中等阻值控制的场景,避免因阻值偏差导致的电路输出误差。
额定功率为100mW(0.1W),最大工作电压为75V。该功率等级适配低功耗电路(如电池供电的可穿戴设备、小型传感器模块),同时75V电压上限可覆盖多数民用/工业低压电路(5V~48V电源系统),无需额外降额设计即可稳定工作。
温度系数为**±100ppm/℃——即每变化1℃,阻值变化仅±0.01%;若环境温度变化100℃(如从-55℃到+45℃),阻值变化仅±0.1%,远优于普通碳膜电阻(通常±500ppm/℃以上),可保证宽温环境下电路性能稳定。
工作温度范围为-55℃~+155℃**,覆盖工业级宽温要求,可应用于户外低温设备、高温车间传感器、汽车辅助电路(非动力系统)等极端环境。
采用0603英制封装(对应公制1608,尺寸约1.6mm×0.8mm×0.5mm),体积仅为传统1/8W插件电阻的1/10左右,大幅提升PCB布局密度,适配高密度集成设计(如智能手机主板、智能手表传感器模块)。封装兼容主流SMT贴装设备,可实现高速批量生产,降低组装成本。
厚膜电阻采用“丝网印刷+烧结”工艺,相比薄膜电阻成本更低,相比碳膜电阻阻值稳定性更好(长期漂移率≤0.1%/1000小时),耐机械冲击(符合JIS C 5102标准)、耐湿度(40℃/90%RH环境下1000小时阻值变化≤0.5%),适合长期连续工作场景。
额定功率下连续工作1000小时,阻值变化≤0.2%;75V工作电压下无击穿、无漏电流超标,符合IEC 61000-4-2(ESD)等安全标准,可降低电路故障风险。
松下作为全球知名电子元器件制造商,ERJ3EKF2211V的生产过程严格遵循ISO 9001质量体系,产品符合RoHS 2.0(无铅环保)、REACH等国际环保标准,同时通过JIS C 5102、IEC 60068等可靠性认证。供货方面,该产品为松下标准产品线,全球供货稳定,可满足批量生产需求,且提供技术支持与售后保障。
该产品凭借“小体积、高精度、宽温稳定”的核心优势,成为众多电子设计中替代传统电阻的优选方案,可有效提升电路集成度与可靠性。

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.
