新的钽电容器对称式设计将ESL(等效串联电感)减少到1nH,适合电信基础设施,互联网,服务器,以及军事和航空航天的应用。

AVX公司扩大了TPM系列包括D型和薄型Y型尺寸多阳极'镜面'配置钽电容器。TPM镜面钽电容采用小外形封装,提供低自感(ESL)和较低等效串联电阻(ESR),适合电信基础设施,互联网,服务器,以及军事和航空航天的应用。新的对称设计将ESL降低到1nH,是标准的D型尺寸元件的一半。


Low ESL enables a higher resonant frequency up to 500kHz (mirror D case), delivering more efficient filtering in DC/DC power switching converters. The new design also reduces the height of the new tantalum capacitors from 4.3mm (E case) to 3.1mm (D case) with further reductions down to 2.0mm maximum height (Y case).

低ESL在DC/DC电源开关转换器中提供更有效的滤波,使得共振频率高达500kHz(镜面D型)。新的设计还使钽电容的高度从4.3mm(E型)降低到3.1mm(D型),进一步降低至最高高度仅为2.0mm(Y型)。


The mirror anode configuration also enhances thermal power dissipation, enabling a higher ripple current to be achieved using only one capacitor. This allows a reduction in the number of capacitors, providing a downsizing of the power supply without compromising the output current ratings.

镜面阳极配置使得仅用一个电容就能得到较高的纹波电流,可以增强热功耗。其能够在不影响额定输出电流的情况下缩小电源,允许减少电容的数量。


Complying with RoHS requirements, TPM capacitors are designed for 3x reflow, 260°C peak temperature lead-free assembly systems, and feature an operating temperature range of between -55°C and +125°C.

根据RoHS的要求,TPM电容设计成3倍回流焊,峰值温度260°C的无铅装配系统,和具有-55°C 到 +125°C的操作温度范围。


Mirror TPM capacitors have been released in a D case size capacitance range of 220 to 1000mF, are rated at 2.5 to 10V and have an ESR range of 25-35mW. Higher voltage (up to 35 and 50V) devices under development will be especially attractive for telecommunication applications where design height is becoming an important parameter: capacitance values 10-22mF, ESR 65-140mW on a single 35-50V capacitor are difficult to attain within the 3.1mm maximum height using any other technology.

镜面TPM电容被制成D型尺寸,容量范围是220 到1000mF,额定电压2.5到10V和ESR范围是25-30mW。更高电压的(高达35和50V)元件还在开发过程中,其将特别适合电信应用,因为设计高度在电信领域中正成为一个重要的参数。采用其他技术很难在最高高度3.1mm的35-50V单电容中实现电容值为10-22mF,ESR为65-140mW。


Samples of even lower profile 2.0mm Y case 220mF 6.3V with ESR 35mW are already available upon request.

根据要求,超薄2.0mmY型220mF 6.3V ESR为35mW的样品也准备开始提供。


Typical pricing for the TPM mirror tantalum capacitor starts at $2.00 each in quantities of 1000 pieces with delivery from stock to 14 weeks.

TPM镜面钽电容的典型价格为每1000枚$2.00起价,14周内交货。
