TCC0805X7R684K500DT是三环电子(CCTC) 推出的通用型贴片多层陶瓷电容(MLCC),专为低压直流/交流电路的滤波、耦合、旁路及储能场景设计。该产品采用0805(英制)/2012(公制)小型化贴片封装,兼顾高容量密度与宽温稳定性,适配消费电子、工业控制、通信等多领域的标准化电路需求,是替代传统铝电解电容、提升电路集成度的优选器件。
容值标称680nF(编码“684”,即68×10⁴pF),精度等级为**±10%(K档)**,满足民用及工业级电路对容值偏差的常规要求,无需额外复杂的匹配设计即可稳定工作。
直流额定电压为50V,覆盖绝大多数低压电子设备的电源轨(如12V、24V、48V系统);交流应用需遵循“交流峰值电压≤直流额定电压”的降额原则,确保长期可靠性。
介质材料采用X7R 温度特性,符合EIA标准:工作温度范围为**-55℃至+125℃**,在此区间内容值变化不超过±15%,相比Y5V等低成本介质,稳定性显著提升。
封装为0805(英制:0.08英寸×0.05英寸;公制:2.0mm×1.25mm),厚度约1.0mm(典型值),适配常规自动化贴片机作业精度,可直接集成于高密度PCB设计中。
0805封装是MLCC主流规格之一,体积小、重量轻,可有效降低整机尺寸与重量,尤其适合智能手机、可穿戴设备、小型通信模块等对空间敏感的产品。
采用多层陶瓷叠层工艺,将高介电常数的X7R介质层(εr≈2000-3000)与镍基内电极交替叠压,经高温烧结成型——既保证680nF的大容量密度,又避免单层电容的体积劣势;X7R介质的高介电常数是实现大容量的核心,同时兼顾温度稳定性。
外端电极采用三层结构(镍层+锡层+抗氧化层),焊接性符合IPC J-STD-002标准,适配回流焊、波峰焊等常规贴片工艺,且抗氧化性能优异,长期使用无脱焊、虚焊风险。
X7R介质的温度特性是该产品核心优势:
该产品因参数均衡,适配多领域场景:
三环电子(CCTC)是国内MLCC主流供应商,产品符合RoHS 2.0、REACH 环保标准,无铅无卤;该产品经过多项可靠性测试:
该产品以高性价比、宽温稳定及小型化优势,成为低压电路设计中替代传统电容的实用选择,适配多行业的标准化应用需求。

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.
