TCC0805X7R683K101DT 是 CCTC(三环)推出的一款贴片多层陶瓷电容器(MLCC),规格为 0805 封装、容值 68nF(0.068µF)、容差 ±10%(K)、额定电压 100V、介质等级 X7R。该系列面向电源去耦、滤波和旁路等一般电子应用,兼顾体积、耐压与成本,在中高电压电源和模拟电路中具有良好的性价比。
X7R 为二类陶瓷介质,具有较大的介电常数,能够在较小体积下实现较高容值,但相对于 C0G/NP0,X7R 在温度和电压下的电容变化较明显,因此适用于去耦和滤波等对精度要求不极端的场合。
CCTC(三环)作为元器件供应商,在 MLCC 的可靠性测试上通常包括温度循环、热冲击、耐压测试、绝缘阻抗和蒸汽回流等项目。实际设计时应查阅厂方数据手册获取详细的电气曲线(如 DC-bias 曲线、频率响应、耐压与绝缘数据)以及封装尺寸图和推荐焊盘尺寸,确保在目标应用环境下满足寿命和可靠性要求。
总结:TCC0805X7R683K101DT 在体积小、耐压高(100V)且容值适中的条件下,适合用于常规电源去耦和中高压滤波场景。设计中需重点关注 X7R 的直流偏置和温漂特性,并遵循厂方焊接与储存要求以保证长期稳定性与可靠性。若需精确的电气曲线或样品测试数据,建议索取厂方数据手册或样品进行验证。

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.
