FRC0603F1R50TS是FOJAN(富捷)推出的通用型小功率厚膜贴片电阻,主打「小体积+高性价比+稳定精度」,针对需要高密度PCB设计、宽温环境适应性的场景,广泛适配消费电子、工业控制、车载辅助电路等领域。其核心定位是满足批量生产中对阻值一致性、温度稳定性的基础需求,同时通过0603封装实现空间优化,适合从可穿戴设备到小型工业控制器的多元应用。
标称阻值1.5Ω,精度±1%——比常规±5%电阻的阻值偏差缩小4倍,能有效避免因阻值波动导致的电路性能偏差(例如:电池保护板电流采样中,1%精度可将过流保护阈值偏差控制在1%以内,提升保护可靠性)。
±200ppm/℃——表示温度每变化1℃,阻值变化±200×10⁻⁶倍。以工作温度范围-55℃~155℃(温差210℃)计算,阻值最大变化量为$\pm 210 \times 200 \times 10^{-6} \times 1.5Ω \approx \pm 0.063Ω$,稳定性满足宽温环境下的电路需求。
-55℃+155℃——覆盖工业级(-40+85℃)及部分高温场景(如车载发动机舱附近的辅助电路),长期工作可靠性符合厚膜电阻的典型宽温标准。
采用0603英制封装(对应公制1608,尺寸1.6mm×0.8mm),是贴片电阻的主流小封装之一,适配高密度PCB设计(例如智能手机主板的空间利用率提升约30%对比0805封装)。
通过「丝网印刷电阻浆料+高温烧结」工艺制成,相比薄膜电阻成本降低约20%,同时兼顾±1%精度,适合大规模批量应用;端电极采用无铅锡基合金,兼容回流焊、波峰焊工艺,焊接后剪切强度≥10N(符合IPC标准)。
FOJAN(富捷)作为国内电阻制造领域的成熟品牌,FRC0603F1R50TS符合以下标准:
该产品以「性能均衡+成本可控」为核心竞争力,是中小功率电路中替代进口电阻的高性价比选择。
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.
