ARG02FTC4702 产品概述
一、产品简介
ARG02FTC4702 为 Viking（光颉）系列薄膜贴片电阻，封装为 0402（公称尺寸约 1.0×0.5 mm），阻值 47 kΩ，精度 ±1%，标称功率 62.5 mW，工作电压 50 V，温度系数（TCR）±25 ppm/℃。器件工作温度范围为 -55℃ 至 +155℃，适用于对体积、稳定性和温漂有较高要求的小尺寸电子设计。
二、主要参数（要点）
- 类型：薄膜电阻（SMD）
- 阻值：47 kΩ
- 精度：±1%
- 标称功率：62.5 mW（0402）
- 最大工作电压：50 V
- 温度系数：±25 ppm/℃
- 工作温度范围：-55℃ ~ +155℃
- 封装：0402
- 品牌：Viking（光颉）
三、性能特点
- 低温漂：±25 ppm/℃ 的 TCR 提供良好的温度稳定性，适合精密分压、滤波与检测电路。
- 高精度：±1% 公差保证阻值一致性，减少电路校准工作量。
- 良好抗噪声特性：薄膜工艺本征噪声低于普通碳膜电阻，利于低电平信号处理。
- 小型高密度：0402 封装有利于 PCB 面积受限的产品实现高密度布局。
四、使用与计算建议
- 最大连续电流：受限于最大工作电压及阻值，按额定电压 50 V 计算，最大电流约 I = V/R = 50/47000 ≈ 1.06 mA；按功率限制，理论电流上限为 sqrt(P/R) ≈ 1.15 mA，但仍以额定电压与厂家规定为准。
- 功率热降额：在高温或散热条件差的场合需进行功率降额，推荐遵循使用环境的热阻与 PCB 散热设计，避免长期在额定功率下高温工作。
- 焊接工艺：建议采用业界通用的无铅回流焊工艺并遵循厂家温度曲线，避免长时间过高温度或反复热循环。
五、推荐应用场景
适用于精密模拟电路、电压分压、ADC 输入网络、传感器前端、便携设备与通讯终端中对体积与稳定性有要求的场合；亦可用于量产化消费电子与工业控制产品中作为通用精密电阻件。
六、可靠性与选型提示
薄膜材料与小尺寸封装在长期漂移、耐湿性和机械应力下表现良好，但在严苛环境下仍建议进行样品验证。若需特定认证（如可靠性试验报告或环保合规证书），请向供应商索取相应资料以确认满足项目要求。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
