华新科0402X105K100CT是一款多层陶瓷贴片电容(MLCC),品牌为华新科(Walsin),封装规格为0402(公制1005)。其核心电气参数清晰对应型号标识:
该电容属于通用型MLCC,兼顾小型化与性能稳定性,是小型电子设备中高频应用的被动元件。
0402封装是贴片电容的典型小型化封装,英制尺寸为0.04英寸(长)×0.02英寸(宽),转换为公制后为1.0mm×0.5mm,厚度约0.5mm(批次略有差异)。采用无引脚贴片结构,焊盘直接与PCB焊接,适配高密度电路板设计,可有效节省空间。电容重量约0.01g,对设备整体重量影响极小,适合对体积、重量有严格要求的便携类产品。
除核心参数外,该电容的关键电气性能包括:
X5R材质的温度特性定义为:工作温度范围-55℃~+85℃,容值变化±15%。相比Y5V材质(容值变化±20%+85%),X5R的容值稳定性显著提升,可适应温度波动较大的场景(如户外物联网节点、汽车电子周边电路)。在-40℃+85℃的常用温度区间内,容值变化通常控制在±10%以内,保证电路性能一致性。
该电容的小体积、稳定性能使其适用于多种小型化设备:
华新科作为全球知名被动元件厂商,该产品具备以下优势:
该电容凭借小体积、稳定性能与可靠品质,成为小型电子设备中电源滤波、去耦的常用选择。

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.
