FRC0402F1200TS是FOJAN(富捷)推出的一款0402封装贴片厚膜电阻,专为小体积、低功耗电子设备设计,核心参数精准覆盖常规电路的匹配需求:
该产品参数经出厂严格校准,一致性符合行业标准,可直接替代同类进口/国产0402封装电阻。
采用0402英制封装(对应公制尺寸1.0mm×0.5mm),体积紧凑,适合高密度贴装设计——可在单位面积内实现更多电路布局,满足智能穿戴、小型通信设备等对空间严格要求的场景。封装引脚采用镀锡工艺,焊接兼容性好,适配无铅回流焊、波峰焊等主流贴装工艺。
基于厚膜丝网印刷工艺制造,具备三大核心优势:
±1%的阻值精度可满足多数电路的阻抗匹配需求(如分压电路、信号衰减电路);±100ppm/℃的温度系数在宽温范围内表现稳定——以155℃为例,相对于25℃基准温度,阻值变化仅为120Ω×100ppm×130℃=1.56Ω,仍在±1%精度区间内,无需额外温度补偿。
62.5mW额定功率适配低功耗电路(如传感器信号调理、LED驱动辅助电路);50V最大工作电压可避免小信号电路中因电压波动导致的击穿问题,提升电路可靠性。
-55℃~+155℃的工作温度范围覆盖了工业控制、汽车电子次级电路的典型环境(如汽车发动机舱附近、户外工业传感器节点),无需额外降温/保温措施即可稳定工作。
FOJAN对该产品进行了多项可靠性测试,确保长期使用稳定性:
产品符合IEC 61000-4-2(静电放电)、IEC 61000-4-3(射频电磁场辐射)等电磁兼容标准,可适配复杂电磁环境。
实际使用功率建议不超过额定功率的70%(即≤43.75mW),避免过热导致阻值漂移;高温环境(>125℃)下,降额比例需提升至50%(≤31.25mW)。
严格遵循最大工作电压50V的限制,若电路电压波动可能超50V,需串联TVS管等保护元件。
0402封装体积小,贴装时需注意:
未开封产品存储在-20℃~+30℃、湿度≤60%的环境中,开封后建议12个月内使用完毕,避免引脚氧化影响焊接质量。
FRC0402F1200TS凭借紧凑封装、稳定性能及宽温适应性,成为小体积电子设备的优选电阻元件,可满足多领域的常规应用需求。

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.
