FRC0402F4700TS是富捷电子(FOJAN)推出的0402封装厚膜贴片电阻,专为小型化、高密度PCB设计的电路场景打造。其核心优势在于小体积下兼顾基础精度与环境适应性,广泛适配以下领域:
该电阻体积仅1.0mm×0.5mm,能有效节省PCB布局空间,满足当前电子设备“轻薄化”的设计趋势。
作为厚膜贴片电阻的典型代表,FRC0402F4700TS的电气参数精准覆盖基础应用需求,关键参数如下:
标称阻值470Ω(编码“4700”),精度等级±1%,满足大部分常规电路的阻值控制要求(如分压电路的电压精度、限流电路的电流稳定性)。对于精度要求更高的场景,可通过多电阻并联/串联校准,但基础应用无需额外操作。
温度系数(TCR)±100ppm/℃,即温度每变化1℃,阻值变化±0.01%;温度变化100℃时,阻值变化±1%,符合一般工业级电路的温度稳定性要求(如户外小型设备的环境波动场景)。
-55℃~+155℃,覆盖低温环境(如北方户外设备)与高温环境(如小型家电内部散热区域),无需额外散热设计即可稳定工作。
FRC0402F4700TS采用0402封装(公制1005),具体物理参数如下:
厚膜电阻的膜层采用高温烧结工艺,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好,是平衡成本与性能的优选方案。
FRC0402F4700TS通过多项可靠性测试,满足工业级应用要求:
此外,厚膜电阻的膜层具有较强的抗机械应力能力,在PCB弯曲(如可折叠设备)场景下仍能保持稳定性能。
FRC0402F4700TS由富捷电子(FOJAN) 生产,该品牌是国内专注于被动元器件的知名厂商,产品覆盖电阻、电容、电感等全系列,广泛应用于华为、小米、美的等主流客户的供应链中。
富捷电子的品质保障体系包括:
FRC0402F4700TS是一款高性价比的0402封装厚膜贴片电阻,兼顾小体积、基础精度与环境适应性,适合各类小型化电子设备的常规电路设计,是电子工程师平衡成本与性能的可靠选择。
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.
