TCC0603X7R332K251CT是三环电子(CCTC) 推出的通用型多层陶瓷贴片电容(MLCC),针对中高压、小型化电路场景设计。型号中各字符对应核心参数:
该产品属于工业级通用MLCC,兼顾小型化、中高压耐受能力与温度稳定性,适配多领域电路需求。
容值为3.3nF(332),精度±10%(K档)。此参数覆盖大部分通用电路的滤波、去耦需求,既避免过高精度带来的成本冗余,又能满足工业级电路对容值稳定性的基本要求(如电源纹波抑制、信号耦合)。
额定电压250V,高于0603封装常见的100V、16V等级,可直接应用于中压场景(如24V~250V直流/交流电源)。实际使用建议降额至80%(≤200V),避免过压导致陶瓷介质击穿。
采用X7R温度系数,定义为:
相比Y5V(容值变化±20%~-82%),X7R的温度稳定性更优,适合对温度敏感的电路(如汽车电子辅助模块、工业传感器);相比NPO(COG,容值变化±0.05%),X7R容值密度更高,适配小型化需求。
0603封装(1.6mm×0.8mm×0.8mm典型厚度)体积紧凑,适合高密度PCB设计(如智能插座、路由器电源模块),焊接兼容性符合IPC J-STD-020标准。
X7R属于铁电陶瓷,介电常数(εr)约2000~4000,容值密度是NPO的10倍以上,在0603小封装下实现3.3nF/250V的参数平衡。陶瓷介质无极性,无需区分正负极,安装更便捷。
经三环电子严格测试:
三环电子是国内MLCC龙头企业,专注陶瓷电容研发生产20余年,产品通过ISO 9001、IATF 16949(汽车级)、RoHS 2.0、REACH等认证,供应全球30+国家/地区客户。
产品采用无铅无卤工艺,符合欧盟环保指令,避免对人体和环境的潜在危害,适配出口产品设计。
TCC0603X7R332K251CT是一款高性价比的通用中压MLCC,兼顾小型化、温度稳定性与可靠性,适配工业、消费电子、通信等多领域场景。三环电子的成熟工艺与认证体系,确保产品在恶劣环境下长期稳定工作,是替代进口中压MLCC的可靠选择。

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.
