FRL0603JR400TS 产品概述

一、产品简介

FRL0603JR400TS 为 FOJAN(富捷)出品的贴片厚膜电阻,封装为 0603(约 1.6 × 0.8 mm)。标称阻值 400 mΩ(即 0.4 Ω),精度 ±5%(J),额定功率 100 mW,额定工作电压 100 V。温度系数(TCR)为 ±300 ppm/℃,工作温度范围 -55 ℃ 至 +155 ℃。该型号适用于空间受限且需测量或限制小电流的表面贴装电路。

二、主要参数(要点)

  • 阻值:400 mΩ(0.4 Ω)
  • 精度:±5%(J)
  • 功率:100 mW(额定)
  • 工作电压:100 V
  • 温度系数:±300 ppm/℃(典型)
  • 工作温度:-55 ℃ ~ +155 ℃
  • 封装:0603(贴片)
  • 工艺:厚膜电阻

三、电性能示例计算

  • 最大允许直流电流(理论):I_max = sqrt(P/R) = sqrt(0.1 / 0.4) ≈ 0.5 A(在额定功率与适宜散热条件下)。
  • 最大压降(在 I_max 下):V = I·R ≈ 0.5 A × 0.4 Ω = 0.2 V。
  • TCR 换算:±300 ppm/℃ 对应阻值随温度每升高 1 ℃ 变化约 0.12 mΩ(0.00012 Ω)。
    以上数值用于选型与热设计时作为参考,实际允许电流应参考电路散热与封装环境并按厂商降额曲线处理。

四、典型应用场景

  • 低电流电流检测(精度要求不高的电流取样)
  • 便携设备与消费类电子的小信号限流或分流器件
  • 电源管理、偏流设定、电流监测回路
  • 需要小体积、表面贴装的热敏/电阻网络中作为分流元件

五、装配与使用建议

  • 推荐使用标准无铅回流焊工艺,遵循器件厂商的回流温度曲线;避免超时、高温冲击。
  • PCB 焊盘设计与焊膏量要适配 0603 尺寸,保证良好热传导与焊接可靠性。
  • 对于持续接近额定功率的工况,应考虑散热和降额(高温时功率需按厂方曲线线性降额至环境温度上限)。
  • 避免在安装或使用过程中施加过大的机械应力、弯曲或剪切力,清洗时使用推荐溶剂以免损伤电阻层。

六、可靠性与采购要点

FRL0603JR400TS 采用厚膜工艺,具有良好的可批量生产性能与稳定性。订购时请确认阻值、精度和封装规格,并索取最新的产品数据表与温度/功率降额曲线以便精确设计。若用于关键测量场合,建议进行样件测试验证其在目标环境下的长期漂移和温度响应。

总结:FRL0603JR400TS 是一款适合小体积、低功率电流取样与限流的厚膜 0603 贴片电阻,选型时应关注功率降额、热管理及安装工艺以保证可靠性与测量精度。

Sourcing availability signal

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
