TDK 型号 C1005C0G1H101JT000F 为贴片多层陶瓷电容(MLCC),规格为 0402(公称尺寸 1.0×0.5mm),容量 100pF,公差 ±5%(J),额定电压 50V,介质类型为 C0G(亦称 NP0)。该系列属于温度特性稳定的一级介质,满足高精度和高稳定性电路的需求。器件符合无铅与 RoHS 要求,适用于常温回流焊工艺。
C0G 介质具有极低的温度系数(典型 0±30 ppm/°C),在 -55°C 到 +125°C 范围内容量变化极小,电压系数也可忽略,老化率接近零,介电损耗低,等效串联电阻(ESR)和等效串联电感(ESL)均较小,适合高频和射频场合使用。0402 小封装在提供较好寄生参数的同时,具有很高的安装密度,但单颗能量承载与电压冲击能力有限,应注意实际工况下的电压和机械应力。
0402 极小封装易发生“立碑”或焊接不良,建议采用对称焊盘设计、控制焊膏用量与回流曲线、使用精确的贴装设备。回流峰值温度按器件与工艺规范(一般 ≤260°C)控制。PCB 布局上,去耦电容应尽量靠近被去耦芯片的电源引脚并短路回地,必要时增加过孔以降低回路阻抗。避免在 PCB 焊接后板弯或机械应力集中处贴装,以防开裂。
如需更高容量或更小尺寸可考虑 X7R/Y5V 等介质,但会牺牲温度与电压稳定性。若要求更低损耗或高频性能,可在 0201/0402 中选择同系列 C0G/NP0 产品。选型时重点核对频率范围、温度范围、额定电压与焊接工艺相容性,确保满足电气与可靠性要求。若需样品或批量资料,可参考 TDK 官方数据手册以获取完整的性能曲线与封装信息。

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.
