0402 / 0603 / 0805 / 1206 / 1210 / 2010 / 2512
Derating Curve
Surge/Pulse protection is essential for all circuit designs. PWR series, size from 0402-2512, Tolerance 0.5%~5%, 1ohm~20Mohm. High power is available. It has outstanding pulse load capability, the superior pulse withstanding resistor is suitable for protection of electronic circuits against extreme pulses. Resistors withstand the pulse is required in the circuit where large current is instantaneously applied. Pulse means the overload of large power and with long duration (large energy) Anti-pulse resistors are prevent the damage even if large power is instantaneously applied

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.
Lightning Surge
Resistors are tested in accordance with IEC 60115-1 using both 1.2/50us and 10/700 pulse shapes. The limit of acceptance is a shift in resistance of less than 1% from the initial value.
