AR03FTC1782 产品概述

一、概述

AR03FTC1782 是 Viking(光颉) 推出的高精度薄膜贴片电阻,封装为常见的 0603(约 1.6 mm × 0.8 mm)。该型号为 17.8 kΩ、±1% 精度、薄膜工艺,适合对温漂与稳定性有较高要求的小型化电子产品。额定功率为 62.5 mW(约 1/16 W),额定工作电压 50 V,工作温度范围宽 (-55 ℃ 至 +155 ℃),是精密测量与微型化电路设计的理想选择。

二、主要参数

  • 型号:AR03FTC1782
  • 品牌:Viking(光颉)
  • 阻值:17.8 kΩ
  • 精度:±1%
  • 功率:62.5 mW
  • 最高工作电压:50 V
  • 温度系数(TCR):±25 ppm/℃
  • 工作温度:-55 ℃ ~ +155 ℃
  • 封装:0603(约 1.6×0.8 mm)
  • 工艺:薄膜电阻

三、产品特性

  • 高精度:±1% 标称精度,适合对阻值要求严格的电路。
  • 低温漂:±25 ppm/℃ 的低 TCR,保证随温度变化的阻值稳定性,适合精密测量与参考电路。
  • 宽温度范围:-55 ℃ 至 +155 ℃,适应严苛环境与工业级应用。
  • 小型化封装:0603 体积小,适合高密度 PCB 布局与便携设备。
  • 薄膜工艺:具有良好的长期稳定性和噪声性能,优于一般厚膜产品。

四、典型应用

  • 精密测量仪器与传感器前端(ADC、放大器分压等)
  • 高频滤波与阻抗匹配电路
  • 工业控制和汽车电子(在符合系统要求的前提下)
  • 电源监控、电压采样与参考网络
  • 消费类小型电子产品的精密阻抗元件

五、使用建议与注意事项

  • 电压限制:实际使用时保证两端电压不超过 50 V,避免超过最大额定功率导致热失效。
  • 功率与散热:封装小、功率低,实际可耗功率依 PCB 散热及环境温度而异。高温环境下应按系统要求进行功率降额设计(derating)。
  • 焊接工艺:兼容常见的无铅回流焊流程。建议遵循 PCB 与元器件制造商的回流曲线,避免长时间高温暴露以保护电阻性能。
  • PCB 布局:采用对称焊盘并参考 IPC 推荐的 0603 焊盘设计,保持焊盘清洁,减少热梯度与机械应力对阻值稳定性的影响。
  • 环境与可靠性:储存与使用环境应避免腐蚀性气体与湿度引起的湿热应力,必要时采用密封或涂覆保护。

六、包装与采购

AR03FTC1782 提供适用于自动贴装的卷带包装(Reel),便于 SMT 自动化生产。采购时请确认供应商的规格书、检验报告与环境合规证书,以满足量产与质量追溯要求。

如需详细规格书(含机械尺寸、焊盘建议、功率降额曲线与可靠性测试数据),可联系 Viking(光颉) 或授权代理商获取原厂文档以用于设计验证与生产准备。

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
