ERJ3EKF2003V是松下(PANASONIC)推出的厚膜贴片电阻,核心参数精准匹配多场景应用需求,具体如下:
±1%的精度避免了阻值偏差对电路参数的影响,例如在传感器信号调理中,可确保微弱模拟信号的分压/限流精准度;厚膜工艺赋予其长期稳定性——高温老化后阻值变化率≤±0.5%,减少了设备维护成本。
-55℃至+155℃的工作范围覆盖了汽车发动机舱(高温)、户外通信基站(低温)等极端场景;±100ppm/℃的温度系数意味着在125℃时,阻值变化仅约±0.7%,远低于多数应用的误差容忍度。
100mW额定功率匹配小信号电路(如射频前端、传感器反馈),150V最大工作电压兼容中等电压的分压、限流设计,无需额外降额即可满足常规应用需求。
0603封装(1.6mm×0.8mm×0.45mm)支持自动化回流焊/波峰焊,适配高密度PCB设计,节省电路板空间,适合智能手机、可穿戴设备等便携式产品。
在温度、压力传感器的信号调理中,用于精准分压/限流,避免因阻值偏差导致的测量误差;宽温范围适配工业现场的温度波动(如车间-20℃至60℃环境)。
适用于汽车仪表盘指示灯驱动、车身控制模块(BCM)反馈回路;-55℃至+155℃的温度范围可应对发动机舱附近的高温,满足汽车级IATF16949认证要求。
0603封装适配智能手机、平板电脑的高密度PCB,用于电源管理模块的分压检测、音频电路的信号衰减;100mW功率匹配小电流信号处理需求。
在基站、路由器的射频小信号电路中,用于阻抗匹配、信号衰减;厚膜工艺的稳定阻值有助于提升射频信号传输质量,减少信号失真。
标准英制0603封装(公制1608),尺寸紧凑且一致性高,支持自动化生产,贴装效率是传统插件电阻的3倍以上,降低了生产制造成本。
采用丝网印刷+高温烧结工艺:将电阻浆料印刷在氧化铝陶瓷基底上,经1000℃以上烧结形成致密电阻层,具有阻值范围宽、抗脉冲能力强、成本适中的特点;相比薄膜电阻,在200kΩ大阻值下仍保持性能一致性。
松下通过严格的浆料配方(自主研发低噪声电阻浆料)、烧结温度控制,确保每批次产品的阻值精度、温度系数偏差≤±0.2%;出厂前经过100%阻值测试、高温老化(85℃/1000h),符合工业级可靠性要求。
产品通过ISO9001、IATF16949质量体系认证,满足汽车电子、工业控制的严苛可靠性要求;松下的全球供应链体系确保供货稳定性。
符合欧盟RoHS指令(无铅、无镉、无汞)、REACH法规,适配全球绿色电子产品设计,避免出口限制风险。
ERJ3EKF2003V凭借平衡的精度、宽温适应性与小型化设计,成为工业控制、汽车电子、消费电子等领域小功率电路的优选厚膜贴片电阻,可满足不同场景的可靠性与成本需求。
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.
