FMF06FTHR005-LH是PSA(信昌电陶)推出的低阻值高精度贴片电流采样电阻,核心功能是实现电力电子系统中的电流监测、分流检测与反馈控制,是过流保护、功率调节、状态监测的关键被动元件。其应用覆盖多领域:
该产品围绕“低阻、高精度、稳定可靠”设计,核心参数适配主流电流采样需求:
标称阻值5mΩ(毫欧级),是大电流采样的理想选择——100A电流下,电阻压降仅0.5V,既避免过高功耗(如100A持续工作时功耗0.5W,远低于1W额定值),又便于ADC采样(无需高压放大电路)。额定功率1W,可承受短时间过载(如电机启动峰值电流),满足动态负载场景。
采用1206(英制)贴片封装(尺寸3.2mm×1.6mm),符合主流SMT生产线要求,支持高速自动化贴装,降低生产工艺复杂度,适配高密度PCB设计。
PSA针对该产品的可靠性进行了针对性优化,确保复杂工况下的稳定性:
采用厚膜电阻技术,电阻体与96%氧化铝陶瓷基底结合牢固,抗机械应力能力强;电阻浆料均匀印刷,激光调阻实现高精度阻值控制。
封装设计优化了热传导路径,热量可快速通过PCB散出,避免局部过热导致阻值漂移或失效。
PSA(信昌电陶)是国内专注被动元件研发生产超20年的企业,产品覆盖汽车电子、工业控制、新能源等领域,核心优势:
采用高纯度金属电阻浆料(镍铬系)与优质陶瓷基底,确保阻值一致性与长期稳定性;
从浆料印刷、烧结到激光调阻、测试均实现全自动化,减少人为误差,每批次阻值离散度控制在±0.2%以内;
每只产品经过100%阻值测试、功率老化测试(1.2倍额定功率下24小时)、温漂测试,出厂合格率100%。
FMF06FTHR005-LH凭借低阻、高精度、宽温稳定与贴片适配性,成为新能源、电机驱动、电源系统等领域的高性价比电流采样方案。PSA的制造工艺与可靠性保障,使其可替代进口同类产品,满足国内中高端电子设备的国产化需求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
