FS46X105K251EFG是PSA(信昌电陶)推出的高压商用级贴片多层陶瓷电容(MLCC),针对中高压、宽温区电路场景优化设计,核心参数清晰明确:
该型号依托PSA成熟的MLCC生产工艺,具备以下核心优势:
宽温区稳定性
X7R介质是平衡容值稳定性与成本的主流选择,FS46X105K251EFG在-55℃至125℃范围内,容值变化控制在±15%以内,可有效避免环境温度波动导致的电路性能漂移,适配工业、车载(若符合车规)等复杂场景。
中高压可靠性
额定电压250V DC满足多数中高压电路需求,直流工作电压下无明显容值衰减;长期应用建议工作电压不超过200V DC(额定电压80%降额),进一步降低失效风险。
高频特性均衡
MLCC本身的低等效串联电阻(ESR)、低等效串联电感(ESL)特性,使该型号适合高频滤波、耦合、去耦等应用;1825封装优化了电极设计,在10MHz~100MHz频段内损耗稳定。
批量一致性
±10%的容值精度属于商用级标准,PSA通过严格的生产管控确保批量产品的容值、电压特性一致性,减少电路调试难度。
端电极与焊接
采用镍/锡(Ni/Sn)镀层端电极,兼容无铅回流焊工艺,焊接强度符合IPC标准;镀层抗硫化性能良好,降低存储/使用中的电极氧化风险。
包装方式
常规采用12mm编带卷盘包装,每盘10000片,适合SMT自动化贴装,编带张力、抗静电性能符合电子元器件包装规范。
FS46X105K251EFG的参数特性使其适配以下场景:
PSA(信昌电陶)是国内MLCC领域主流制造商,专注陶瓷电容研发10余年,FS46X105K251EFG的可靠性保障包括:
该型号凭借中高压、宽温区的性能优势,成为工业、消费电子等领域的实用型高压MLCC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.
