Although the TCR of Bulk Metal ® Foil resistors is considered extremely low, this characteristic has been further refined over the years.The VFCP Series utilizes ultra precision Bulk Metal ® Z-Foil.The Z-Foil technology provides a significant reduction to the resistive element’s sensitivity to ambient temperaturevariations (TCR) and to self heating when power is applied (power coefficient).Along with the inherently low PCR and TCR, Z-Foil technology also provides remarkably improved load life stablility, low noise and availability of tight tolerance.The Flip Chip configuration provides a substantial PCB space saving of more than 35 % vs. a surface mount chip with wraparound terminations. The VFCP is available in any value within the specified resistance range.Our Application Engineering Department is available to advise and make recommendations. For non-standard technical requirements and special applications, please contact us.FEATURES•Temperature Coefficient of Resistance (TCR):± 0.05 ppm/°C typical (0 °C to + 60 °C)± 0.2 ppm/°C typical (- 55 °C to + 125 °C, +25 °C Ref.)•Tolerance: to ± 0.01 % (100 ppm) •Power Coefficient “ΔR due to self heating”5 ppm at Rated Power•Load Life Stability (70 °C for 2000 hours): ± 0.005 % (50 ppm)•Power Rating to: 600 mW at + 70 °C•Electrostatic Discharge (ESD) above 25 000 V•Resistance Range: 10Ω to 150 k Ω (for lower and higher values, please contact us)•Non Inductive, Non Capacitive Design •Short time overload ≤ 0.005 % (50 ppm)•Non hot spot design•Rise time: 1ns without ringing •Current Noise: - 40 dB•Voltage Coefficient < 0.1 ppm/V •Non Inductive: < 0.08 µH•Terminal Finishes available:Lead (Pb)-freeTin/Lead Alloy•Matched sets are available per request•Any value available within resistance range (e.g. 1K2345)•Prototype samples available from 48 hours.

0805电阻 功率
0805电阻功率1. 引言电阻是电子电路中常见的元件之一，用于限制电流、分压、分流等各种应用。
其中，0805电阻是一种表面贴装型号，其尺寸为0.08英寸×0.05英寸（2mm×1.25mm），被广泛应用于各种电子设备中。
本文将介绍0805电阻的功率特性及其相关知识。
2. 0805电阻的基本结构和工作原理0805电阻由导体材料和绝缘材料组成。
导体材料通常是金属或合金，如铜、镍、铬等；绝缘材料通常是陶瓷或有机高分子材料。
在制造过程中，导体材料被加工成薄片或薄膜，并与绝缘材料层层叠加，形成线性结构。
当通过0805电阻时，导体内部会发生电流通过，并产生一定的热量。
根据欧姆定律和功率公式（P=I²R），功率大小与通过电阻的电流以及电阻本身的阻值有关。
3. 0805电阻的功率特性3.1 额定功率0805电阻的额定功率是指在标准工作条件下，电阻能够稳定工作的最大功率。
额定功率一般由制造商在产品规格书中给出，单位为瓦特（W）。
超过额定功率使用0805电阻可能会导致电阻温度升高、损坏甚至发生火灾等严重后果。
3.2 温升系数温升系数是指0805电阻在额定功率下，温度上升的速度。
温升系数越小，表示电阻在相同功率下会产生较小的温升。
温升系数一般由制造商提供，并以ppm/℃（百万分之一/摄氏度）为单位。
3.3 高温环境下的功率降额0805电阻在高温环境中会因为散热不良而导致其承载能力降低。
根据MIL-STD-202标准，当环境温度超过0805电阻的最大允许工作温度时，其额定功率会随着环境温度的增加而降低。
3.4 瞬态功率瞬态功率是指0805电阻在短时间内承受的功率峰值。
当电阻所处的电路中出现瞬态电流时，其功率可能会瞬间增大，超过额定功率。
因此，在设计电路时需要考虑0805电阻的瞬态功率特性，以避免电阻损坏。
4. 选择0805电阻功率的注意事项4.1 根据应用场景选择额定功率在选择0805电阻时，需要根据具体应用场景和所需功率来确定额定功率。

0805电阻高度
0805电阻高度一、什么是0805电阻0805电阻是一种表面贴装技术（SMT）元件，常用于电子设备中。
它的尺寸为0.08英寸× 0.05英寸（2.0毫米× 1.25毫米），因此得名为0805。
该尺寸的电阻广泛应用于各种电路板，包括手机、计算机、汽车和消费类电子产品等。
二、0805电阻的特点1. 尺寸小巧由于0805电阻的尺寸相对较小，因此可以在紧凑的空间内安装更多的元件。
这使得它成为现代电子设备设计中不可或缺的组成部分。
2. 高精度0805电阻通常具有较高的精度，可达到1%或更高。
这意味着它们可以提供稳定且准确的电阻值，确保整个电路的正常运行。
3. 良好的热耐受性由于其材料和设计特点，0805电阻具有良好的热耐受性。
在高温环境下，它们能够保持稳定性能，并避免过热引发的损坏。
4. 良好的电性能0805电阻具有低电感和低电容的特点，这使得它们在高频和射频应用中非常适用。
它们能够提供准确的阻抗匹配，确保信号传输的稳定性和质量。
5. 易于自动化生产由于0805电阻采用表面贴装技术，可以通过自动化设备进行大规模生产和组装。
这降低了生产成本，并提高了产品的可靠性。
三、0805电阻的应用领域0805电阻广泛应用于各种电子设备和行业。
以下是它们常见的应用领域：1. 通信设备0805电阻被广泛用于手机、通信基站、卫星通信等设备中。
它们在调制解调器、天线、滤波器等模块中发挥重要作用，确保通信信号的稳定传输。
2. 计算机与网络设备0805电阻在计算机主板、显卡、路由器等设备中起到关键作用。
它们帮助控制电流流向，并提供准确的分压功能，以确保计算机和网络设备的正常运行。
3. 汽车电子0805电阻在汽车电子产品中广泛应用，包括发动机控制单元（ECU）、仪表盘、导航系统等。
它们能够提供稳定的电阻值，以确保汽车电子系统的可靠性和性能。
4. 消费类电子产品0805电阻也被广泛应用于消费类电子产品，如平板电视、音频设备、游戏机等。
