ERJ2RKF80R6X 产品概述

一、产品简介

ERJ2RKF80R6X 为 PANASONIC(松下)系列厚膜贴片电阻,封装尺寸为 0402(公制 1005)。标称阻值 80.6Ω,精度 ±1%(E96 系列),额定功率 0.1W(100mW),温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃ 至 +155℃。该型号以小体积、高稳定性和工业级温度范围为特点,适用于空间受限且需要中等精度阻值的各种电子设备。

二、主要电气与热特性

  • 阻值:80.6Ω,±1%(适合精密分压、偏置等场合)。
  • 额定功率:100 mW(在规定的环境与散热条件下)。
  • 温度系数:±100 ppm/℃,指示随温度变化的阻值漂移量,适合对温漂有中等要求的应用。
  • 额定工作电压:50 V(产品规范标称值),但实际工作电压需同时满足功耗限制(见下节说明)。

三、功率与工作电压说明(关键提示)

标称额定功率为 0.1W,因此在使用时应确保施加电压与电流不会使器件超过功耗极限。根据 P = V^2 / R,可计算不超过额定功率的最大连续电压:

  • 最大连续电压 Vmax ≈ sqrt(P × R) ≈ sqrt(0.1 × 80.6) ≈ 2.84 V。
    对应最大连续电流约 Imax ≈ Vmax / R ≈ 35 mA。
    因此即便器件标注“工作电压 50V”,在实际电路中仍必须受限于功率关系,避免过压导致过热或失效。

四、环境与可靠性

  • 工作温度范围 -55℃ 到 +155℃,适合汽车电子(非车规最高等级)、工业控制、通信及仪器仪表等宽温场合。
  • 厚膜工艺在长时漂移、热循环和机械应力下表现稳定,但仍建议按制造商试验规范(如温度循环、湿热、耐焊接热)进行确认以满足具体应用的可靠性要求。

五、封装与安装注意事项

  • 0402 小尺寸便于高密度贴装,但对回流焊热曲线、焊接时间和焊膏量敏感。建议使用兼容无铅回流工艺并参考 PANASONIC 的回流曲线建议。
  • 焊接后避免强烈弯曲基板或机械挤压,以防电阻体开裂或焊点破坏。
  • 存储与搬运应避免潮湿、污染和静电环境,尽量使用原厂卷带(Tape & Reel)包装并在规定时限内回流焊接。

六、典型应用

  • 精密分压器、基准网络、偏置/限流电阻。
  • 移动设备、消费类电子、通信设备、传感器前端及测试测量仪器中对尺寸与精度有要求的场合。
  • 在高电压但低功耗的隔离网络中可作为阻值元件(注意功率限制)。

七、选型与替代建议

  • 若系统存在较高功耗或较大浪涌电流,应考虑更大封装(如 0603/0805)或更高功率等级(≥1/4W)的元件。
  • 若要求更低温漂可选用薄膜或金属膜电阻,TCR 可低至 ±25 ppm/℃ 或更好。
  • 采购时核对批次、RoHS/无铅合规以及松下的具体型号编码与规格表,以确保与设计要求一致。

以上为 ERJ2RKF80R6X 的要点说明。针对具体电路的热设计与长期可靠性评估,建议结合整板热仿真与实际环境测试进行最终验证。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
