FS55X335K251EHG 是 PSA(信昌电陶)出品的一款贴片多层陶瓷电容(MLCC),额定电压 250V,标称电容 3.3µF,初始容差 ±10%,介质类型为 X7R,封装为 2220。该器件兼顾了中高电压承受能力与较大容量,适用于对体积、电压与电容密度有一定要求的电源滤波与能量储存场合。
2220 封装使器件在保持较大电容量的同时仍兼顾可贴装性。实际选型时请参考厂方机械图纸确认尺寸、公差及引脚形貌。建议在 PCB 设计时采用合适的过孔与焊盘设计,考虑贴片应力释放和焊点形状,降低裂纹风险。
如需样品或批量采购,请向 PSA(信昌电陶)经销渠道索取 FS55X335K251EHG 的完整数据手册与可靠性报告。选型时若需替代件,应重点比较在额定电压、容值、介质类型、封装尺寸和 DC 偏置特性下的实际曲线,确保在目标工作条件下满足电路要求。

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.
