FRC0402F3742TS 产品概述

一、产品简介

FRC0402F3742TS 是 FOJAN(富捷)推出的一款贴片厚膜电阻,封装为 0402(约 1.0 mm × 0.5 mm),阻值 37.4 kΩ,精度 ±1%。该器件属于低功耗、微型化的 SMD 元件,设计用于要求体积小、稳定性好的表面贴装电路。典型型号标识为 FRC0402F3742TS,适合批量贴装与自动化生产。

二、主要技术参数

  • 电阻类型:厚膜电阻(Thick film SMD resistor)
  • 阻值:37.4 kΩ
  • 精度:±1%
  • 额定功率:62.5 mW(常温下)
  • 额定工作电压:50 V
  • 温度系数(TCR):±100 ppm/℃(典型)
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 封装:0402(约 1.0 mm × 0.5 mm)
  • 安装方式:表面贴装(SMT)

说明:根据功率与阻值的物理关系,从功率上计算的理论最大允许电压为 V = sqrt(P·R) ≈ 48.3 V。产品标称工作电压为 50 V,实际使用时请以数据手册和电路热控条件为准,并在高温环境下进行功率降额。

三、主要特点与优势

  • 体积极小:0402 封装适合高密度布板和微型化设计,有利于便携式与消费电子产品的空间优化。
  • 精度可靠:±1% 精度满足常用模拟电路、分压器和精密偏置网络的要求。
  • 宽温适应性:-55 ℃ 至 +155 ℃ 的工作温度适合工业级应用环境。
  • 良好的一致性与可重复性:厚膜工艺成熟,适合大批量生产与成本敏感型设计。
  • 贴片工艺兼容:适用于常规无铅回流焊流程,便于 SMT 自动化贴装。

四、典型应用场景

  • 精密分压与偏置电阻网络
  • 传感器前端、AD/DA 采样网络中的参考与阻抗匹配
  • 移动终端、可穿戴设备和便携电子产品的低功耗电路
  • 工业控制、通信设备中占板面积受限的阻值元件
  • 高密度混合信号板(模拟/数字混合)中的去耦和阻抗设定

五、封装与装配建议

  • 推荐遵循 0402 标准焊盘尺寸和过孔布局,以保证良好的焊接强度与热传导。
  • 使用符合元件温度等级的无铅回流焊曲线进行焊接,避免超过最大温度应力。
  • 在靠近高热源(如功率器件)处布局时,应考虑功率降额与散热路径,避免长期过温运行。
  • 高电压应用请在布局时增加爬电距离与绝缘防护,避免表面泄露或击穿。

六、可靠性与质量控制

FOJAN 厚膜电阻经过片上可靠性测试,能满足常见的温度循环、湿热和机械应力试验要求。TCR ±100 ppm/℃ 表明在温度变化时阻值变化可控;长期漂移主要受厚膜材料与封装工艺影响,建议在关键精度场合进行实际环境下的提前验证。若需更严格的可靠性保证或认证信息,请向供应商索取完整的检验报告与可靠性试验数据。

七、选型与采购提示

  • 型号示例:FRC0402F3742TS(FOJAN,0402,37.4 kΩ,±1%)
  • 典型包装形式为盘带(Tape & Reel),便于 SMT 贴片机送料;TS 后缀通常表示卷装形式。
  • 在批量采购前建议索取样品并完成电路验证,确认回流焊兼容性与环境应力下的性能稳定性。
  • 如需更高精度、更低 TCR 或特殊认证(如汽车级 AEC-Q),请联系厂商或授权分销商获取替代产品或定制方案。

结语:FRC0402F3742TS 以其微小封装、良好精度与宽温特性,适用于对体积与稳定性有较高要求的电子产品设计。针对具体应用的热管理和电压降额建议在设计初期予以充分考虑,以确保长期稳定运行。若需完整数据手册或批量供货信息,请联系 FOJAN 或其授权代理。

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
