ERJ2RKF1652X 产品概述

一、产品简介

ERJ2RKF1652X 为 PANASONIC(松下)系列 0402 封装厚膜贴片电阻,标称阻值 16.5 kΩ,精度 ±1%,额定功率 100 mW,工作温度范围 -55 ℃ 至 +155 ℃。该器件采用常规厚膜工艺,体积小、可靠性高,适合高密度贴装和空间受限的应用场合。

二、主要电气参数

  • 阻值:16.5 kΩ(1% 精度)
  • 额定功率:100 mW(在厂家规定基准温度下)
  • 最高允许工作电压(器件等级):100 V(器件绝缘/耐压等级)
  • 温度系数(TCR):±100 ppm/℃
  • 工作温度:-55 ℃ ~ +155 ℃
  • 封装:0402(≈1.0 mm × 0.5 mm)

注:额定功率与最大允许电压需要同时考虑。基于功率限制,可计算出在不超过 100 mW 的条件下的最大安全电压及电流:

  • 最大安全电压(按 P = V^2 / R):Vmax ≈ √(0.1 W × 16500 Ω) ≈ 40.6 V
  • 最大安全电流(按 P = I^2 × R):Imax ≈ √(0.1 W / 16500 Ω) ≈ 2.46 mA
    因此,尽管器件标注的耐压可达 100 V,但持续施加近 100 V 会使耗散功率远超额定值,应以功率限制得出的 ~40.6 V 为长期使用参考。

三、关键性能与使用注意

  • 精度 ±1% 可满足多数分压、采样与偏置网络的中高精度要求;TCR ±100 ppm/℃ 表明温度漂移中等,温差较大时(例如 25 ℃ → 125 ℃)阻值变化约为 ±1%。
  • 0402 小封装有利于高密度布局,但热容小、散热条件有限,贴片后的环境温度与 PCB 散热能力会直接影响允许功率,建议在设计时考虑功率降额。
  • 对于噪声、稳定性与长时间漂移,如需更高稳定性或低噪声要求,应选择薄膜或金属膜精密电阻系列。

四、典型应用

适用于便携设备、消费电子、通信设备、信号处理、ADC/DAC 前端的分压与采样电阻、偏置/上拉/下拉电阻、滤波/阻抗匹配网络等多种场景。宽温度范围使其可用于工业级应用,但若需汽车级资格(AEC-Q)请确认具体产品认证。

五、焊接与储存建议

  • 采用推荐的 0402 焊盘和回流焊工艺,遵循厂方或 IPC 焊接曲线进行无铅回流;避免重复高温回流导致阻值漂移或热应力损伤。
  • 储存应避免潮湿、高温及强腐蚀性气体环境,长期存放建议封装卷盘密封防潮并在规定期限内使用。

六、选型与设计建议

  • 设计时优先按功率降额与实际工作温度计算允许电压/电流,必要时留有余量以提高可靠性。
  • 若电路中存在瞬态高压,应评估脉冲能量并考虑并联限流/保护措施,或选择更大功率/更高稳定性的器件。
  • 在对温度漂移与精度要求更严格的应用(如高精密采样)可考虑选用更低 TCR 与更高稳定性的薄膜电阻件。

总体而言,ERJ2RKF1652X 在体积、精度与温度适应性之间提供了良好平衡,适合空间受限且对精度有中高要求的电子设计。

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
