FNF05JT-102 贴片厚膜电阻产品概述

一、产品基本定位与型号解析

FNF05JT-102是PSA信昌电陶推出的常规精度贴片厚膜电阻,定位于中低端电子设备的基础电阻应用,兼顾成本与稳定性能。型号字符对应核心参数:

  • FNF:PSA信昌电陶厚膜电阻系列标识;
  • 05:关联125mW额定功率的封装功率等级;
  • JT:精度等级代码(对应±5%);
  • 102:阻值编码(10×10²=1000Ω=1kΩ)。

二、核心技术参数及性能特性

该产品的参数设计匹配多数常规电路需求,关键指标如下:

  1. 阻值与精度:标称阻值1kΩ,精度±5%,无需额外校准即可满足信号调理、分压等非精密场景;
  2. 功率负载:额定功率125mW,0805封装典型功率等级,可承受瞬间脉冲过载(降额后长期负载建议≤100mW);
  3. 温度特性:温度系数±100ppm/℃(即温度每变1℃,阻值漂移±0.01%),结合-55℃~+155℃宽温范围,适配高低温交替环境;
  4. 材料工艺:厚膜烧结工艺,相比薄膜电阻成本更低,抗机械应力能力更强,适合批量生产。

三、封装与生产兼容性

采用0805贴片封装(英制0.08"×0.05",公制2.0mm×1.25mm),是行业应用最广泛的小型封装之一:

  • 贴装适配:兼容自动贴片机(SMT)高速生产,贴装精度±0.1mm,支持PCB高密度布局;
  • 焊接工艺:端电极镍/锡镀层,兼容回流焊、波峰焊,焊接强度≥10N(符合IPC标准);
  • 尺寸规范:焊盘推荐尺寸2.2mm×1.4mm,适配主流PCB设计软件的封装库。

四、典型应用场景

因性能参数覆盖广,FNF05JT-102可用于以下领域:

  1. 消费电子:手机、平板的信号滤波、电源分压、LED偏置电路;
  2. 工业控制:小型PLC、传感器信号调理、低压电源限流;
  3. 汽车电子:车载多媒体、车身控制模块(BCM)辅助电路(155℃高温适配部分发动机舱周边场景);
  4. 通信设备:路由器、交换机接口电路、电源滤波网络;
  5. 家电产品:智能家电控制板、显示模块分压电路。

五、可靠性与品质保障

PSA信昌电陶对该产品通过多项可靠性测试,确保长期稳定:

  • 环境测试:高温存储(+155℃/1000h)、温度循环(-55℃~+155℃/1000次)后,阻值变化≤±1%;
  • 电性能测试:2倍额定功率过载(5s)、100V耐电压(1min)无击穿;
  • 环保合规:符合RoHS 2.0、REACH标准,无铅无镉;
  • 批次一致性:自动化生产使阻值、功率批次偏差≤±0.5%,满足批量采购需求。

六、选型与使用注意事项

  1. 功率降额:长期工作负载功率不超过100mW(125mW×80%),避免高温衰减;
  2. 温漂匹配:精密仪器需选±1%精度或±50ppm/℃温系型号;
  3. 封装适配:确认PCB焊盘尺寸,避免贴装偏移;
  4. 品牌支持:PSA提供原厂技术文档及小批量样品服务,批量采购可定制阻值微调。

该产品以高性价比、宽温稳定的特点,成为常规电子电路的主流选型之一,适合对成本敏感但要求基础可靠性的批量应用。

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
