FRC0204F1271TS是FOJAN(富捷)针对高密度集成场景推出的小型化厚膜贴片电阻,核心定位为「平衡精度、空间与成本的通用型电阻方案」。其设计围绕两大需求展开:一是适配0402封装的紧凑体积,满足便携设备、小型模块的高密度PCB布局;二是兼顾±1%精度与62.5mW功率的实用性能,覆盖消费电子、工业控制等多数常规电路场景。
标称阻值为1.27kΩ(阻值代码「1271」,遵循E96系列编码规则:前两位为有效数字「12」,第三位为倍率「7」即10⁷?不对,哦1271是12×10⁷?不,等下,1.27kΩ是1270Ω,代码应该是1271(127×10¹=1270Ω),对,修正:阻值代码「1271」对应127×10¹=1270Ω=1.27kΩ),精度等级为**±1%**——无需额外校准即可稳定控制电路参数,满足信号调理、分压网络等对阻值精度要求的场景。
额定功率62.5mW(0.0625W),工作电压50V:在常规电路中可承受合理电压波动,避免因过载导致的阻值漂移或失效,适配多数低压直流/交流电路。
温度系数(TCR)为**±100ppm/℃,工作温度范围覆盖-55℃~+155℃**:宽温范围内阻值漂移控制在较低水平(如155℃时阻值变化约1.5%),可适应户外设备、车载辅助电路等温变较大的场景,远超普通商业级电阻的温度上限。
采用0402英制封装,对应公制尺寸约1.0mm(长)×0.5mm(宽)×0.35mm(厚),体积仅为0603封装的1/4,大幅节省PCB空间,支持高密度集成设计。
采用厚膜印刷工艺制造:电阻膜层厚度均匀(5~10μm),阻值一致性好;陶瓷基底+环氧树脂涂层的结构,兼具抗机械应力与抗潮湿性能,兼容回流焊、波峰焊等常规SMT工艺。
经严格测试验证:
产品老化测试后阻值变化率≤0.3%(典型值),无开路、短路等失效问题,满足电子设备5~10年的使用寿命要求。
FOJAN(富捷)作为国内专业被动元器件制造商,专注电阻、电容研发生产超15年,产品覆盖消费电子、工业、汽车电子等领域。FRC0204F1271TS通过ISO 9001质量管理体系认证,部分批次符合RoHS、REACH环保标准,可满足全球市场的环保要求;同时提供批量一致性保障,适合大规模量产场景。
该产品以「小型化+高性价比+稳定性能」为核心竞争力,是多数紧凑电路设计的优选电阻方案。

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.
