FRC0402F4R70TS是富捷(FOJAN)推出的0402封装厚膜贴片电阻,针对高密度PCB设计优化,兼顾精度、稳定性与成本,适配多领域低功耗电路需求。核心属性如下:
标称4.7Ω±1%精度,满足信号分压、电流采样等基础精密需求,避免阻值偏差导致电路性能波动,适配大多数常规工业/消费电子场景。
额定功率62.5mW,对应工作电压50V,最大工作电流约1.25mA(I=P/U),适配低功耗电路的电流控制(如电池供电终端、传感器信号调理)。
±200ppm/℃表示温度每变化1℃,阻值漂移≈0.02%。在-55℃~+155℃宽温范围内,阻值变化可控,满足极端温变环境(如北方户外设备、车载高温模块)的稳定需求。
覆盖低温(-55℃)与高温(+155℃),适配汽车电子、工业自动化等对温区要求苛刻的领域,无需额外加散热设计。
体积仅≈1.0mm×0.5mm,是贴片电阻中紧凑规格,可显著缩小PCB布局面积,提升电路集成度,适合智能手机、可穿戴设备等轻薄化产品。
采用丝网印刷+高温烧结工艺,相比薄膜电阻成本更低,且抗过载能力强、长期稳定性好;兼容回流焊/波峰焊,适配自动化生产,降低制造成本。
封装采用耐高温环氧树脂,隔离湿气/灰尘;焊接端镀锡处理,确保焊接牢固,无虚焊脱落风险,提升潮湿环境下的使用寿命。
结合参数特性,该产品主要用于:
该产品通过多项行业测试,确保复杂环境下稳定工作:
富捷(FOJAN)是国内被动元件老牌厂商,具备千万级月产能,产品符合RoHS 2.0、REACH环保标准(无铅无卤);提供批量供货保障,针对不良品免费退换,降低客户采购风险。
FRC0402F4R70TS凭借小封装、宽温范围、稳定精度与成本优势,成为多领域电路设计的优选被动元件。
Request for quote
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.
