FRC1206F4703TS 厚膜贴片电阻产品概述

FRC1206F4703TS是FOJAN富捷推出的一款通用型厚膜贴片电阻,采用1206标准封装,针对中小功率电子电路的阻性需求设计,兼具成本优势与稳定性能,广泛适配消费电子、工业控制等多领域应用。

一、产品核心身份与定位

该型号属于厚膜贴片电阻范畴,聚焦常规精度(±1%)、中小功率(250mW) 的应用场景,既满足多数电子设备对阻值精度的基础要求,又能适配高密度PCB的表面贴装工艺,是电子设计中常用的阻性元件选型之一。

二、关键性能参数解析

1. 阻值与精度

额定阻值为470kΩ,精度等级±1%,可满足信号调理、分压电路等对阻值一致性要求不苛刻但需避免较大偏差的场景,避免因阻值误差导致电路性能波动(如分压比偏离设计值)。

2. 功率与电压容量

  • 额定功率:250mW(实际使用建议降额至80%以下,即≤200mW,避免长期过热加速老化);
  • 工作电压:200V(最大连续工作电压,需结合功率公式(P=U^2/R)计算实际功耗,避免过压击穿)。

3. 温度特性

  • 温度系数(TCR):±100ppm/℃,属于厚膜电阻的常规水平,能适应-55℃~+155℃的宽温范围,满足工业、车载等环境温度变化较大的场景;
  • 工作温度范围:-55℃~+155℃,覆盖极端低温(如户外设备冬季运行)与高温(如电源模块内部散热)环境,可靠性表现稳定。

三、封装与物理特性

采用1206英制封装(对应公制尺寸约3.2mm×1.6mm),贴片式结构,适配SMT(表面贴装技术)生产,体积小巧,适合高密度PCB布局(如智能手机、小型控制器等紧凑设备)。厚膜工艺确保产品成本适中,批量生产一致性好,适合大规模应用。

四、典型应用领域

结合性能参数,该电阻可覆盖以下场景:

  1. 消费电子:手机、平板的信号分压电路、LED驱动限流电阻;
  2. 工业控制:PLC输入输出接口的偏置电阻、传感器信号调理电路(如温度传感器的信号放大偏置);
  3. 汽车电子:车载小功率辅助电路(如仪表盘背光控制、胎压传感器接口,符合宽温要求);
  4. 通信设备:射频前端匹配电阻、电源模块分压电路(如4G/5G基站的辅助电源);
  5. 电源系统:开关电源的辅助绕组限流、电压反馈分压(适配200V以内的低压电源场景)。

五、品牌与可靠性保障

FOJAN富捷作为国内专业电子元器件制造商,该产品符合RoHS环保标准,无铅无镉,满足欧盟环保要求。厚膜电阻工艺成熟,批量一致性经过严格测试(如高温老化1000小时、湿热循环40℃/95%RH、焊接可靠性测试等),能满足长期稳定运行需求,适合工业级、商业级电子设备选型。

六、使用注意事项

  1. 功率降额:实际工作功率需低于额定值的80%,高温环境(如>125℃)需进一步降额(参考厂商提供的功率-温度曲线);
  2. 电压限制:连续工作电压不超过200V,脉冲电压需符合规格书要求(避免瞬间过压损坏);
  3. 焊接工艺:适配回流焊(峰值温度≤245℃,时间≤10秒)、波峰焊,避免手工焊接时烙铁温度过高(建议≤350℃)损坏电阻;
  4. 存储条件:建议存储于温度-40℃~+60℃、湿度≤60%的环境,避免受潮导致引脚氧化,影响焊接性能。

该型号以平衡的性能与成本优势,成为电子设计中通用阻性元件的可靠选择,可满足多数中小功率电路的基础需求。

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
