CGA0603X7R103K250JT是HRE芯声品牌推出的通用型多层陶瓷电容(MLCC),采用小型化0603封装,兼顾温度稳定性、容值精度与成本优势,广泛适配消费电子、工业控制等多领域电路需求。以下从核心属性、性能参数等维度展开详细说明。
该型号属于HRE芯声常规X7R系列MLCC,核心定位为中温稳定型通用电容——既满足多数电路对容值偏差的基本要求,又具备较宽温度适应范围,区别于高精度NPO系列(温度特性优但容值窄)和高容值Y5V系列(温度特性差但成本低)。其型号命名对应核心参数:
标称容值10nF,精度±10%(K级),满足90%以上通用电路对容值偏差的要求(如电源滤波、信号耦合无需高精度)。X7R特性使其容值随温度、电压变化幅度远小于Y5V,可避免电路性能波动。
额定直流电压25V,是0603封装MLCC的常规电压等级(高于10V/16V,低于50V)。需注意:
采用X7R温度系数,工作范围**-55℃~+125℃**,容值变化≤±15%(行业标准)。可稳定工作于高温环境(如车载电子、工业现场)或低温环境(如户外设备),无需额外温控设计。
0603封装公制尺寸为1.6mm(长)×0.8mm(宽)×0.8mm(厚)(常规值),适合高密度PCB布局(如手机主板、智能手表模块),有效节省空间。
焊盘符合IPC-A-610标准,支持回流焊、波峰焊:
符合RoHS 2.0(无铅、无镉、无汞)及REACH SVHC要求,可用于全球多数市场电子产品。
该型号因平衡体积、温度特性与成本,广泛应用于:
额定电压+125℃下工作1000小时,容值变化≤±10%,绝缘电阻≥1GΩ,满足5~10年使用周期。
存储温度**-55℃~+150℃**,相对湿度≤60%,开封后3个月内使用(避免引脚氧化)。
综上,CGA0603X7R103K250JT是性价比突出的通用MLCC,适合对温度稳定性有要求、体积受限的电路设计,是HRE芯声中低端市场主力型号之一。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
