0102 / 0204 / 0207
Afnamecurve
Hoog niveau van MELF-metaalfilm precisieweerstand, klaar voor de maten 0102/0204/0207. Strikte toleranties van 0,1%, TC5/10/15/25/50/100ppm. Weerstandsbereik 0,1ohm~3,4Mohm.
De MELF is cilindrisch van vorm en heeft een metaal-elektrode zonder aansluitingen. De landpatroonformaten zijn hetzelfde als die van SMD-chipweerstanden.
Het wordt vervaardigd door een homogene film van NiCr op een hoogwaardig keramisch lichaam aan te brengen. De hoge kwaliteit van MELF-resistors biedt uitstekende elektrische en omgevingsstabiliteit, uitzonderlijke stabiliteit aangetoond gedurende de levensduur, bij bevochtigde omstandigheden en bij kortdurende overbelastingstests.
Korte doorlooptijd, effectieve kostenbeheersing, prijscompetitiviteit

Pulse Weerstand Capaciteit
The single impulse graph is the result of 50 impulses of rectangular shape applied at one-minute intervals. The limit of acceptance was a shift in resistance of less than 1% from the initial value. The power applied was subject to the restrictions of the maximum permissible impulse voltage graph shown.
Continue Puls
The continuous load graph was obtained by applying repetitive rectangular pulses where the pulse period was adjusted so that the average power dissipated in the resistor was equal to its rated power at 70°C. Again the limit of acceptance was a shift in resistance of less than 1% from the initial value.
Frequentiegedrag
Resistors are designed to function according to ohmic laws. This is basically true of resistors for frequencies up to 100kHz. At higher frequencies, there is an additional contribution to the impedance by an ideal resistor switched in series with a coil and both switched parallel to a capacitor. The values of the capacitance and inductance are mainly determined by the dimensions of the terminations and the conductive path length.
The environment surrounding components has a large influence on the behavior of the component on the printed-circuit board.
Bliksemstoot
Resistors are tested in accordance with IEC 60115-1 using both 1.2/50us and 10/700us pulse shapes. The limit of acceptance is a shift in resistance of less than 0.5% from the initial value.
