华新科(Walsin)作为全球被动元器件领域的核心供应商,其1206B104K500CT是一款通用型多层陶瓷电容(MLCC),针对中低频电路的滤波、耦合、旁路等基础需求设计,兼具成本优势与性能稳定性,广泛覆盖消费电子、工业控制等多场景应用。
1206B104K500CT属于华新科常规MLCC产品线,型号编码清晰对应核心参数:
该产品主打中低端通用场景,平衡了容值稳定性、成本与封装密度,是电子设计中最常用的电容型号之一。
容值为100nF(10⁻⁷F),精度±10%(K级),满足大多数通用电路对容值偏差的容忍度(如电源滤波、音频耦合无需极高精度)。若需更高精度(±5%),可选择同系列J级产品(如1206B104J500CT)。
额定电压50V DC,指长期工作时可承受的最大直流电压。实际应用中需注意:交流纹波电压叠加后的峰值电压不得超过50V,否则可能导致电容击穿或性能下降。该电压等级覆盖了多数低压电路(如5V/12V/24V系统的辅助电源)。
采用X7R介质,温度特性符合EIA标准:
相比Y5V(温度系数-30%~+80%)等低稳定度介质,X7R的容值随温度变化更平缓,适合环境温度波动较大的场景(如汽车仪表、工业传感器)。
X7R介质的介电损耗(tanδ)在1kHz下典型值≤5%,适合中低频(DC~10MHz)应用;高频下(>100MHz)损耗会显著增加,此时需改用NPO介质电容,但本产品不适用超高频场景。
该封装是表面贴装(SMD)的通用尺寸,兼容绝大多数贴片机,焊接工艺成熟(回流焊、波峰焊均适用)。
电极采用镍锡(Ni/Sn)镀层,无铅环保(符合RoHS 2.0标准),焊接可靠性高:
通常采用卷带包装(Tape & Reel),每盘数量2000/3000/5000个不等,适合自动化生产。
1206B104K500CT因成本低、性能稳定,广泛应用于以下场景:
若需替换1206B104K500CT,可优先选择同参数、同封装的产品:
若需调整参数:
综上,华新科1206B104K500CT是一款高性价比的通用MLCC,适合大多数中低频电子电路的滤波、耦合需求,是电子设计中不可或缺的基础元器件之一。
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.
