TCC1206X5R685K250HT是三环电子(CCTC) 推出的多层陶瓷贴片电容(MLCC),属于通用型中容量被动元件,针对低中压直流电路设计,适配1206标准贴片封装。型号各部分含义清晰:
容值为6.8μF(685K),初始精度±10%,满足多数通用电路对容值偏差的需求——既避免过度冗余导致成本增加,也能保证滤波、耦合等功能的基本性能,无需额外校准。
额定直流电压为25V,覆盖中低压电路场景(如5V/12V系统的辅助电源、12V LED驱动等),高于常规10V以下电容的应用范围,可适配更多中功率设备。
采用X5R温度系数,符合国际电工委员会(IEC)标准:
1206封装(公制3216)是SMT产线的主流封装之一,尺寸紧凑(3.2mm×1.6mm),适配高密度电路板设计,焊接兼容性好,可通过回流焊、波峰焊等标准工艺批量生产。
X5R的温度特性使其在宽温环境下性能稳定:例如,在-20℃(冬季户外设备)或+70℃(夏季密闭机箱)下,容值变化不超过±15%,避免因温度波动导致电路性能下降(如电源滤波效果减弱、信号耦合失真)。
采用多层陶瓷叠层工艺,电极材料为镍基合金(无铅环保),端电极采用“镍层+锡层”三层结构,有效降低焊接虚焊风险;产品经过高温老化(125℃/1000h)、温度循环(-55℃~+85℃/500次)等可靠性测试,MTBF(平均无故障时间)符合工业级标准。
陶瓷叠层结构具有一定抗振动能力,可承受SMT过程中的机械应力,以及设备使用中的轻微振动(如车载电子、手持设备),减少开路、短路风险。
三环电子(CCTC)是国内被动元件领域的资深厂商,产品通过ISO9001质量管理体系、ISO14001环境管理体系认证,部分型号符合AEC-Q200汽车级标准(支撑车载场景)。其MLCC生产工艺成熟,同批次产品参数一致性高,可降低电路调试难度,适合批量采购。
该电容因“容量适中、温度稳定、电压适配广”,广泛应用于以下领域:
TCC1206X5R685K250HT是一款高性价比通用MLCC,平衡了容量、温度稳定性与成本,适配中低压电路的滤波、耦合、旁路等核心功能,可满足消费电子、工业控制、通信等多领域的批量生产需求,是替代进口同规格产品的可靠选择。

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.
