Metal Film Precision MELF Resistor - CSRV Series

Metal Film Precision MELF Resistor - CSRV Series

High level of MELF metal film precision resistor, ready for the size of 0102/0204/0207. Tight tolerance of 0.1%, TC5/10/15/25/50/100ppm. Resistance range 0.1ohm~3.4Mohm.
The MELF is cylindrical in shape and with metal electrode Leadless face resistor. Land pattern sizes are the same as SMD chip resistors.
It is manufactured by depositing a homogeneous film of NiCr onto a high-grade ceramic body. High quality of MELF resistors offer excellent electrical and Environmental Stability, exceptional stability demonstrated over life, biased humidity, and short time overload testing.Resistor-CSRV derating curve

Pulse Withstanding Capacity
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.

Continuous Pulse
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.

Frequency behavior
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.

Lightning Surge
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.
