华新科0805B103K101CT多层陶瓷电容器产品概述
一、产品核心基本信息
0805B103K101CT是华新科（Walsin） 推出的一款通用型多层陶瓷电容器（MLCC），型号编码清晰对应核心参数：
- 「0805」：英制封装尺寸（0.08英寸×0.05英寸），对应公制2012（2.0mm×1.2mm）；
- 「B」：华新科常规MLCC系列标识；
- 「103」：容值编码（10×10³ pF = 10nF）；
- 「K」：容值精度（±10%）；
- 「101」：额定电压编码（10×10¹ V = 100V）；
- 「CT」：封装/生产批次辅助标识。
该产品兼顾成本与性能，是中低压电子电路的主流选择。
二、关键性能特性解析
2.1 温度系数与宽温适应性
采用X7R温度系数，是平衡稳定性与成本的经典方案：
- 工作温度范围：-55℃ ~ +125℃；
- 容值变化率：全温区≤±15%（25℃基准），优于Y5V/Y5P等低成本电容，适配工业、汽车周边等宽温场景。
2.2 电压与功率适配性
额定电压100V满足多数中低压需求：
- 建议工作电压降额至≤80V（额定值80%），避免长期过压导致老化失效；
- 直流偏置下容值变化小（X7R特性），比高介电常数电容更适合直流偏置电路。
2.3 精度与高频特性
- 容值精度±10%，满足消费电子、工业控制等非超高精度需求（滤波、耦合、去耦）；
- 陶瓷介质高频损耗低，截止频率高，可有效抑制10MHz以下高频噪声。
三、封装与尺寸规格
0805封装是电子行业最常用的表面贴装封装，典型尺寸参数（单位：mm）：
项目 典型值 公差 长度（L） 2.0 ±0.2 宽度（W） 1.2 ±0.2 厚度（T） 0.5 ±0.1 引脚间距 1.0 ±0.1封装采用多层陶瓷叠层结构，内部镍基电极+外部镀锡/镍端子，兼容无铅回流焊，符合RoHS 2.0、REACH环保标准。
四、典型应用场景
该产品因性价比突出，广泛应用于：
- 消费电子：手机、平板的电源滤波（BMS）、音频耦合；
- 工业控制：PLC、传感器模块的信号去耦、电源滤波；
- 通信设备：路由器、交换机的中频滤波、电源模块去耦；
- 汽车电子（周边）：车载导航、中控屏的辅助电路滤波；
- 电源模块：DC-DC/AC-DC转换器的输入输出滤波。
五、质量与可靠性保障
华新科通过多项可靠性测试：
- 环境测试：125℃/1000h高温存储、-55℃~125℃/1000次温度循环；
- 电气测试：绝缘电阻≥10⁹Ω、损耗角正切tanδ≤0.02@1kHz；
- 符合IEC 60384-1、AEC-Q200（可选汽车级）等标准，失效率低，长期稳定。
六、应用注意事项
- 降额设计：高温（125℃）下确认容值变化；工作电压≤80V；
- 安装工艺：回流焊峰值温度≤245℃（时间≤10s），避免机械应力导致陶瓷开裂；
- 精度适配：需极高精度（振荡电路）选NPO，X7R仅适合滤波耦合；
- 静电防护：生产过程需ESD防护，避免静电损伤。
该产品是中低压宽温场景的高性价比选择，可满足多数电子设备的基础滤波耦合需求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
