华新科(Walsin)作为全球知名被动元器件制造商,推出的0603B104K500CT是一款高性能多层陶瓷电容(MLCC),核心参数如下:
X7R介质是该电容的核心优势:在工业级温度范围(-55℃~+125℃)内,容值变化控制在±15%以内,可适配车载、户外设备等温度波动场景,避免因容值漂移导致电路性能波动。
额定电压50V满足中低压电路需求,华新科采用先进叠层工艺,介质层均匀性达微米级,通过温度循环(-55~125℃,1000次)、**湿度加载(85℃/85%RH,1000h)**等可靠性测试,长期使用故障率低。
0603封装体积小,可节省PCB空间30%以上,适配智能手机、智能穿戴等轻薄化产品的紧凑布局;同时支持高密度贴装(每平方厘米可贴装约1000颗),提升电路集成度。
多层陶瓷结构使等效串联电阻(ESR)≤50mΩ(1kHz下),等效串联电感(ESL)≤0.5nH,在10MHz~100MHz高频范围内仍保持良好滤波效果,适合射频、电源模块等场景。
实际工作电压建议不超过额定电压的80%(即40V),避免过压导致介质击穿,延长产品寿命。
若应用环境温度超出-55℃~+125℃,需更换为Y5V(宽容值但漂移大)或NP0(高精度但容值小)介质电容;若需更高精度(如±5%),可选择型号中带“J”代码的同系列产品。
华新科拥有40余年MLCC生产经验,产品通过IATF16949(汽车级)、ISO9001(工业级)认证,端电极采用镍锡镀层,焊接附着力达0.5N以上,降低生产不良率。0603B104K500CT作为成熟型号,广泛应用于全球300+客户的量产项目,是小型化电子设计的可靠选择。
总结:该电容平衡了容值精度、温度稳定性与封装密度,适合对可靠性要求较高的中低压电路,是工程师选型的高性价比方案。

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.
