VPG Foil Resistors VSMP系列電阻器

Vishay Precision Group的VSMP系列Z箔捲繞SMD晶片電阻器的外盒尺寸有0603、0805及1206，是業界首款在一個電阻器內提供高額定功率、優越負載壽命穩定性與極低TCR的設備。Vishay Precision Group的VSMP系列Z箔捲繞SMD晶片電阻器採用超精密的Bulk Metal®Z箔技術，在接通電源（功率係數）時可大大減小電阻元件對環境溫度變化(TCR)及自熱的靈敏度。VSMP系列電阻器採用了Z箔 技術，該技術可提供更優越的負載壽命穩定性、低噪音及緊密度容限。VSMP系列Z箔電阻器擁有全捲繞端接，可確保在製造過程中實現安全操作，並在多個熱循環過程中保持穩定性。VSMP系列箔捲繞SMD晶片電阻器包括TCR標準0.05 ppm/ºC（0ºC至+60ºC）、標準0.2 ppm/ºC（-55ºC至+125ºC，+25ºC ref.）；負載壽命穩定性為±0.005%（70ºC時），額定功率時為2000小時；電阻範圍：100Ω至5kΩ（外盒尺寸0603）及10Ω至125kΩ（外盒尺寸0805，1206）；允差值為±0.01%；功率係數「自熱導致的ΔR」：額定功率時為5ppm；+70ºC時額定功率為750mW（外盒尺寸0805、1206），+70ºC時為100mW（外盒尺寸0603）。

The Z-foil technology incorporated into the VSMP Series resistors also provides improved load life stability, low noise, and availability of tight tolerance. VSMP Series Z-foil resistors have a full wraparound termination which ensures safe handling during the manufacturing process and provides stability during multiple thermal cyclings.
