精密電路中選擇采樣電阻時的首要考慮因素應該是精密電阻器的穩(wěn)定性，因為現(xiàn)在的精密儀表中的IC都具有自校準功能，所以采樣電阻的精度已經(jīng)不是首要考慮的因素了，而如果采樣電阻穩(wěn)定性不高，自校準后，采樣電阻偏移就會導致自校準功能失去意義，儀表也就偏離了其精度要求。

The 1st important point of sample resistor selection is the stability instead of tolerance, since the tolerance could drift out of spec if the precision resistors are not stable!

Thunder Precision Resistor has been making ultra precision resistors with ultra high stability and reliability.

金屬膜精密電阻的主體通常為圓柱形；線繞精密電阻則有圓柱形、扁柱形和長方框架形幾種；金屬箔精密電阻則常呈方塊形或片形。線繞精密電阻的匝數(shù)較多時，往往采用無感繞制法繞制，正向繞制的匝數(shù)和反向繞制的匝數(shù)相同，以盡量減小分布電感。長方框架形的線繞精密電阻通常是設備制造廠根據(jù)需要專門定制的，常用于儀器儀表。

Thunder Precision resistor makes ultra precision resistors especially metal film resistors and resistor networks with tolerance less than 0.01%!
