FRC0402J681 TS 厚膜贴片电阻产品概述

一、产品定位与核心特性

FRC0402J681 TS是FOJAN(富捷) 针对高密度、小功率电路推出的0402封装厚膜贴片电阻,核心定位为「常规电路通用型电阻」,兼顾性能稳定性与成本经济性。其核心特性包括:

  1. 小体积高密度:0402封装适配紧凑PCB布局,满足便携式设备、小型化模块的空间限制;
  2. 宽温稳定可靠:工作温度覆盖-55℃~+155℃,温度系数±100ppm/℃,宽温环境下阻值漂移极小;
  3. 精度适配主流:±5%精度(行业J档)覆盖80%以上常规电路需求,无需额外校准;
  4. 厚膜工艺优势:陶瓷基厚膜结构耐机械冲击、抗环境腐蚀,长期使用可靠性优于薄膜电阻。

二、关键参数详解

该电阻核心参数严格遵循电子元件行业标准,关键指标及实际意义如下:

  • 阻值与精度:标称阻值680Ω(三位数代码「681」,即68×10¹),±5%精度满足大多数分压、限流、滤波电路的匹配要求(如分压电路中无需高精度校准即可实现稳定输出);
  • 功率与电压:额定功率62.5mW,最大工作电压50V,适合小电流信号场景(计算可得最大持续电流≈9.5mA,满足一般传感器接口、音频电路需求);
  • 温度特性:温度系数(TCR)±100ppm/℃,即温度每变化1℃,阻值变化仅±0.068Ω,宽温下性能稳定;
  • 环境适应性:存储/工作温度-55℃~+155℃,符合工业级、汽车级辅助电路的环境要求。

三、封装与物理特性

采用0402英制贴片封装(公制1005),物理尺寸约1.0mm(长)×0.5mm(宽)×0.35mm(厚),焊盘间距约0.6mm,适配常规SMT贴装工艺(支持自动贴片机高速生产)。封装材料为陶瓷基厚膜结构,表面镀镍/镀锡,焊接兼容性好,且符合RoHS 2.0无铅环保标准。

四、典型应用场景

因小体积、稳定性能,该电阻广泛应用于以下领域:

  1. 消费电子:智能手机、平板、智能穿戴的信号分压、滤波网络(如音频接口、传感器接口电路);
  2. 工业控制:PLC模块、传感器信号调理电路(如温度传感器的分压参考,宽温特性适配工业现场);
  3. 汽车电子:车载辅助电路(如仪表盘背光调节、小功率传感器接口,满足-40℃~+125℃汽车级需求);
  4. 通信设备:路由器、交换机的射频前端小信号电路(高密度布局适配小型化通信模块)。

五、可靠性与品质保障

FOJAN对该电阻做了多重可靠性验证,确保长期使用稳定:

  • 工艺验证:厚膜工艺通过1000次高低温循环(-55℃~+155℃)、1000h湿热测试(85℃/85%RH),阻值漂移≤0.5%;
  • 机械测试:通过1000g机械冲击(1ms)、振动测试(20Hz~2000Hz),无开路/短路故障;
  • 批量管控:每批次抽样检测通过率≥99.9%,阻值分布符合正态分布,一致性强。

六、品牌与供货说明

FOJAN(富捷)专注被动元件研发生产15+年,产品覆盖电阻、电容、电感全系列,服务300+国内外电子厂商。FRC0402J681 TS采用卷盘包装(每盘10000pcs),常规订单供货周期7~15天,支持样品申请与小批量定制,紧急订单可加急处理。

该产品以「稳定可靠、成本可控」为核心优势,是常规电子电路中替代进口电阻的高性价比选择。

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
