TCC0402X7R104K500AT是三环电子(CCTC) 推出的通用型多层陶瓷贴片电容(MLCC),属于小型化表面贴装元件,专为中低压电子电路的滤波、耦合、去耦等场景设计。型号中各字符的核心含义清晰可辨:
标称容值为100nF(0.1μF),精度等级为**±10%(K档)**,无需额外高精度筛选即可直接应用,满足多数通用电路对容值偏差的基础要求。
额定直流电压为50V,可承受短时间过压(通常为额定电压的1.5~2倍),适配50V以下中低压直流电路,避免高压击穿风险。
采用X7R陶瓷材料,温度特性符合国际通用标准:
介质损耗角正切值(tanδ)较低(通常<2% at 1kHz),适合高频信号耦合;同时具备较好的频率响应,可覆盖10kHz~100MHz的常用电子电路频段,满足多数消费电子与通信设备的信号传输需求。
采用0402英制封装(公制1005),典型尺寸为:
多层陶瓷叠层结构(镍电极+陶瓷介质),表面贴装设计(无引线),兼容标准SMT工艺(回流焊、波峰焊),焊接可靠性高,适合大规模自动化生产,降低产线不良率。
结合参数特点,该电容主要应用于以下领域:
三环电子(CCTC)是国内MLCC领域的主流厂商,该产品具备以下可靠性优势:
TCC0402X7R104K500AT是一款高性价比的通用MLCC,兼具小型化、宽温稳定、高可靠性等核心特点,覆盖中低压电子电路的多数通用需求,是消费电子、工业控制等领域的优选元件之一。

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.
