TCC0603COG680J500CT是三环电子(CCTC) 推出的高频稳定型贴片多层陶瓷电容(MLCC),属于C0G(NP0)系列核心产品。该电容采用0603(英制0.06×0.03英寸)标准贴片封装,专为对容值稳定性、损耗特性要求严苛的电路设计,额定直流电压50V,标称容值68pF,精度±5%(J档),广泛适配消费电子、工业控制、通信等领域的高频/精密电路需求。
标称容值为68pF,精度等级为J档(±5%),无需额外匹配补偿即可满足多数精密电路对容值偏差的要求,有效避免滤波、耦合功能的参数漂移。
采用C0G(NP0)温度系数,容值随温度变化极小:在-55℃~125℃宽温范围内,容值变化率≤±30ppm/℃,且损耗角正切值(tanδ)典型值≤0.0002,是高频振荡器、滤波器的理想选择。
额定直流电压为50V DC,交流额定电压需按频率降额(如1kHz时约35V AC);绝缘电阻典型值≥10¹⁰Ω(25℃/1min),确保电路长期工作无漏电流干扰。
高频下低损耗特性显著:1MHz频率下Q值典型值≥1000,有效降低信号传输损耗,提升射频电路的信号纯度。
该产品采用0603贴片封装(公制尺寸:1.6mm×0.8mm×0.8mm),符合EIA标准,适配常规贴片生产线的贴装工艺。封装结构为多层陶瓷叠层+镍/锡镀层端电极,端电极尺寸(焊盘)为0.3mm×0.5mm,兼具抗机械应力与耐焊接热冲击能力。
因C0G的高稳定性与低损耗特性,主要应用于:
三环电子作为国内电容行业核心厂商,该产品通过以下认证与测试:
该产品平衡了高稳定性、小体积与可靠性,是高频精密电路的高性价比选择。

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.
