ERJ2RKF8063X 产品概述

一、产品简介

ERJ2RKF8063X 为松下(PANASONIC)系列贴片厚膜精密电阻,0402 封装,阻值 806 kΩ,精度 ±1%,额定功率 100 mW,额定工作电压 100 V。工作温度范围为 -55 ℃ 至 +155 ℃,温度系数(TCR)为 ±100 ppm/℃。该型号兼具小型化、高密度贴装与良好精度,适用于对体积和精度均有要求的电子设备中。

二、主要性能参数(速览)

  • 电阻类型:厚膜贴片电阻(精密级)
  • 阻值:806 kΩ(标称)
  • 精度:±1%
  • 额定功率:100 mW
  • 额定工作电压:100 V(最大工作电压)
  • 温度系数:±100 ppm/℃
  • 工作温度:-55 ℃ ~ +155 ℃
  • 封装:0402(约 1.0 × 0.5 mm)

补充计算(便于设计验证):

  • 在额定工作电压 100 V 时,器件耗散功率 P = V^2 / R ≈ 10000 / 806000 ≈ 0.0124 W(≈12.4 mW),远小于额定 100 mW。
  • 在不受电压限制时,根据额定功率计算可承受的最大电压 Vmax = sqrt(P · R) ≈ sqrt(0.1 · 806000) ≈ 284 V(但实际应用应以额定工作电压 100 V 为限)。

三、典型应用场景

  • 高阻抗电路:偏置网、漏电流测量、输入阻抗要求高的放大器前端。
  • 精密分压器与采样电路:在空间受限的便携式/便携医疗设备中用于构建电压采样点。
  • 仪器仪表与传感前端:需耐高温、长期稳定的阻值元件场合。
  • 高密度 PCB 与移动终端:0402 小封装便于实现高密度布局。

四、设计与使用建议

  • 功率与电压:尽管器件额定功率为 100 mW,但受限于封装及制造公差,建议在正常工作中留有裕量;电压不得超过 100 V。
  • 热管理:在高环境温度下应参考制造商的功率降额曲线进行降额设计;尽量避免在高温、高功耗下连续工作。
  • 焊接与制程:0402 为微小封装,推荐采用标准回流焊工艺,遵循 IPC/JEDEC 回流温度曲线,避免超温或重复多次回流。
  • PCB 布局:为降低热堆积及应力,尽量避免将高功耗器件密集排列,焊盘尺寸与过孔布局应符合厂商建议以保证可靠焊接。
  • 环境与清洗:厚膜电阻对常规清洗工艺耐受性良好,但酸性或强腐蚀性清洗剂应避免长期接触。

五、可靠性与品质提示

  • 长期稳定性依赖于制造工艺与使用环境,±100 ppm/℃ 的 TCR 表明在温度变化时阻值会产生可测的漂移,精密应用可考虑额外的温度补偿或使用低 TCR 器件。
  • 推荐在关键应用场景做样机验证,包含湿热、温度循环、焊接后阻值漂移等可靠性试验,以满足最终产品寿命与稳定性要求。

六、选型与采购注意事项

  • 确认具体产品编号、包装形式(卷带卷盘)与符合的环保/认证要求(如 RoHS)。
  • 在批量采购前建议获取并核对厂商完整数据手册(datasheet),尤其是功率降额曲线、焊接温度极限与机械尺寸图。
  • 若对温漂或噪声有更高要求,可与厂商或代理商沟通同系列中低 TCR 或金属膜/薄膜替代型号。

总结:ERJ2RKF8063X 为一款适合高阻值、空间受限场合的 0402 精密厚膜贴片电阻,具有 ±1% 精度与较宽的工作温度范围。在电压和热管理上留有裕量并按制造商的工艺建议使用,可在移动终端、测量与传感等多种应用中获得稳定表现。若用于关键精度或高可靠性场景,建议参照完整数据手册并进行必要的可靠性验证。

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
